AdvancedCriteria (SmartClient Enterprise Server API 12.1p (2024-11-05))

java.lang.Object
- com.isomorphic.criteria.AdvancedCriteria

```
public class AdvancedCriteria
extends java.lang.Object
```
AdvancedCriteria is a format for representing search criteria which may include operators on field values such as "less than", or may include sub-clauses such as several criteria applied to fields joined by an "OR" operator.
The server-side AdvancedCriteria handling feature is only available with the Power and Enterprise Editions of SmartClient; the Pro Edition is limited to ordinary criteria handling on the server side)
AdvancedCriteria objects can be created directly in java. For example:
```
 AdvancedCriteria criteria = new AdvancedCriteria(DefaultOperators.And, new Criterion[]{
   new SimpleCriterion("countryCode", "contains", "C"),
   new SimpleCriterion("countryName", "startsWith", "C")
 });
 
```
In addition to building a raw AdvancedCriteria object as described above, the DataSource.parseAdvancedCriteria(Map) and Evaluator.parseAdvancedCriteria(Map) methods may be used to create AdvancedCriteria based on simple fieldName / value mappings.
Also an AdvancedCriteria instance can be retrieved from a DSRequest via DSRequest.getAdvancedCriteria() These same AdvancedCriteria objects can be directly created server side, and applied to a DSRequest via DSRequest.setAdvancedCriteria(AdvancedCriteria).

  - convertRelativeDates
```
public void convertRelativeDates()
```
    Converts any relative dates in this AdvancedCriteria into absolute dates with now as the relative point in time. Note that this API is not able to distinguish between "date" and "datetime" fields, so it may not convert values as you expect. If this causes a problem in your use case, consider using AdvancedCriteria.convertRelativeDates(DataSource)
    See DataSource.convertRelativeDates(Criterion) for more information on relative date conversion.
    
    See Also:
    
    DataSource.convertRelativeDates(Criterion)
  - convertRelativeDates
```
public void convertRelativeDates(DataSource ds)
```
    Converts any relative dates in this AdvancedCriteria into absolute dates with now as the relative point in time. See DataSource.convertRelativeDates(Criterion) for more information on relative date conversion. Note that this API is able to distinguish between "date" and "datetime" fields, unlike AdvancedCriteria.convertRelativeDates().
    
    See Also:
    
    DataSource.convertRelativeDates(Criterion)
  - convertRelativeDates
```
public void convertRelativeDates(java.util.Date baseDate)
```
    Converts any relative dates in this AdvancedCriteria into absolute dates with now as the relative point in time. See DataSource.convertRelativeDates(Criterion) for more information on relative date conversion. Note that this API is not able to distinguish between "date" and "datetime" fields, so it may not convert values as you expect. If this causes a problem in your use case, consider using AdvancedCriteria.convertRelativeDates(Date, DataSource) or DataSource.convertRelativeDates(Criterion, Date, DataSource)
    
    Parameters:
    
    baseDate - the point in time to convert the relative dates against. If null, it will be defaulted to now.

    DataSource.convertRelativeDates(Criterion)
  - convertRelativeDates
```
public void convertRelativeDates(java.util.Date baseDate,
                                 DataSource ds)
```
    Converts any relative dates in this AdvancedCriteria into absolute dates with now as the relative point in time. See DataSource.convertRelativeDates(Criterion) for more information on relative date conversion. Note that this API is able to distinguish between "date" and "datetime" fields, unlike AdvancedCriteria.convertRelativeDates(Date). This API always uses the server's local timezone to determine what is meant by concepts such as "the staert of today" or "the end of tomorrow"
    
    Parameters:
    
    baseDate - the point in time to convert the relative dates against. If null, it will be defaulted to now.
    
    ds - the DataSource associated with this AdvancedCriteria. The dataSource definition is used to determine whether a Java Date value should be treated as a logical "date" or a "datetime".
    
    See Also:
    
    DataSource.convertRelativeDates(Criterion, Date, DataSource)
  - convertRelativeDates
```
public void convertRelativeDates(java.util.Date baseDate,
                                 DataSource ds,
                                 boolean useEmbeddedTZ)
```
    Converts any relative dates in this AdvancedCriteria into absolute dates with now as the relative point in time. See DataSource.convertRelativeDates(Criterion) for more information on relative date conversion. Note that this API is able to distinguish between "date" and "datetime" fields, unlike AdvancedCriteria.convertRelativeDates(Date). This API can potentially use the client's timezone to determine what is meant by concepts such as "the start of today" or "the end of tomorrow", if the client supplies its timezone in the relativeDate definition. See DataSource.convertRelativeDates(Criterion, Date, DataSource, boolean) for important information about using the client timezone when converting relative dates.
    
    Parameters:
    
    baseDate - the point in time to convert the relative dates against. If null, it will be defaulted to now.
    
    ds - the DataSource associated with this AdvancedCriteria. The dataSource definition is used to determine whether a Java Date value should be treated as a logical "date" or a "datetime"
    
    useEmbeddedTZ - If true, the conversion will use the timezone embedded in the relativeDate definition sent up by the client (if the client sent that information). This allows the server to perform date conversions that match what the client would have done, even if the server and the client are configured for different timezones

  - decodeClientCriteria
```
public static AdvancedCriteria decodeClientCriteria(java.lang.String clientCriteria)
                                             throws java.lang.Exception
```
    Decodes a client side criteria which has been serialized for storage. Criteria are expected to be serialized as JSON, specifically using the "logicalDateConstructor" mode of the client-side JSONEncoder class.
    
    Parameters:
    
    clientCriteria - a string of the encoded/serialized criteria to decode.
    
    Returns:
    
    the advanced criteria representation of the client criteria.
    
    Throws:
    
    java.lang.Exception - if there is a problem parsing the client criteria.

  - getFieldCriterions
```
public java.util.Set getFieldCriterions(java.lang.String fieldName)
```
    Returns all criterions matching the given fieldName.
    
    Parameters:
    
    fieldName - - name of field to search value for.
    
    Returns:
    
    all criterions matching fieldName. The Set will be empty if no matches were found.
  - getCriteriaAsMap
```
public java.util.Map getCriteriaAsMap()
```
    Convert AdvancedCriteria into Map object.
    
    Returns:
    
    AdvancedCriteria represented as Map.
  - fromCollections
```
public static AdvancedCriteria fromCollections(java.lang.Object criteria)
```
    Creates an AdvancedCriteria object from Java collections.
    You may pass collections reflecting simple or advanced criteria to this method.
    If criteria were passed as simple Criteria this method will convert them to the more general AdvancedCriteria format by turning them into an AND Criterion containing one or more "equals" Criteria.
    Note that AdvancedCriteria will only be able to be executed by the built-in server DataSources (JPA, Hibernate, SQL) in Power Edition and above.
    
    Parameters:
    
    criteria - - criteria in java collections (nested maps) format
    
    Returns:
    
    The resulting advanced criteria
  - fromCollections
```
public static AdvancedCriteria fromCollections(java.lang.Object criteria,
                                               java.lang.String operator)
```
    Creates an AdvancedCriteria object from Java collections.
    You may pass collections reflecting simple or advanced criteria to this method.
    If criteria were passed as simple Criteria this method will convert them to the more general AdvancedCriteria format by turning them into an AND Criterion containing one or more Criteria with the operator specified by the operator argument to this method.
    Note that AdvancedCriteria will only be able to be executed by the built-in server DataSources (JPA, Hibernate, SQL) in Power Edition and above.
    
    Parameters:
    
    criteria - - criteria in java collections (nested maps) format
    
    operator - - default operator to use
    
    Returns:
    
    The resulting advanced criteria
  - fromCollections
```
public static AdvancedCriteria fromCollections(java.lang.Object criteria,
                                               OperatorBase operator)
```
    Creates an AdvancedCriteria object from Java collections.
    You may pass collections reflecting simple or advanced criteria to this method.
    If criteria were passed as simple Criteria this method will convert them to the more general AdvancedCriteria format by turning them into an AND Criterion containing one or more Criteria with the operator specified by the operator argument to this method.
    Note that AdvancedCriteria will only be able to be executed by the built-in server DataSources (JPA, Hibernate, SQL) in Power Edition and above.
    
    Parameters:
    
    criteria - - criteria in java collections (nested maps) format
    
    operator - - default operator to use
    
    Returns:
    
    The resulting advanced criteria
  - toCollections
```
public static java.util.Map toCollections(Criterion criterion)
```
    The "collections" format of AdvancedCriteria is a simple Java representation of criteria that is equivalent to the typical JavaScript / JSON representation.
    Each normal Criterion is represented as a Java Map with "fieldName" and "operator" keys, and a possible "value" or "start" and "end" keys based on the OperatorValueType com.smartgwt.client.types.OperatorValueType.
    A Criterion which is a logical operator ("and", "or", "not") has a key "criteria" which contains sub-criteria as a List of Maps.
    This is a useful format for serialization, although note that serializing to JSON will not correctly round-trip Date objects without further processing, since JSON has no way of directly serializing dates.
    Use AdvancedCriteria.fromCollections(Object) to create an AdvancedCriteria object from the result of this method.
    
    Parameters:
    
    criterion - The passed criterion.
    
    Returns:
    
    AdvancedCriteria represented as Map.
  - asCriterion
```
public Criterion asCriterion()
```
    Convert AdvancedCriteria into Criterion format.
    
    Returns:
    
    AdvancedCriteria represented as Criterion.
