java.lang.Object
- java.lang.Enum<MultipleFieldStorage>
- - com.smartgwt.client.types.MultipleFieldStorage

All Implemented Interfaces:

ValueEnum, java.io.Serializable, java.lang.Comparable<MultipleFieldStorage>
```
public enum MultipleFieldStorage
extends java.lang.Enum<MultipleFieldStorage>
implements ValueEnum
```
Options for how values are stored for a field that is multiple:true. See DataSourceField.multipleStorage.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`JSON` values are serialized to JSON.
`NONE` no transformation is applied to values; server-side field value remains a Java List when passed to the execute(Fetch\|Add\|Update\|Remove) method of the server-side DataSource class
`SIMPLESTRING` values are saved as a simple delimeter-separated string.

- Enum Constant Detail
  - SIMPLESTRING
```
public static final MultipleFieldStorage SIMPLESTRING
```
    values are saved as a simple delimeter-separated string. Delimeter can be configured via DataSourceField.multipleStorageSeparator. An empty array is stored as "", and null as the database null value.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "simpleString".
  - JSON
```
public static final MultipleFieldStorage JSON
```
    values are serialized to JSON. Empty array as a distinct value from null (it appears as the text "[]").
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "json".
  - NONE
```
public static final MultipleFieldStorage NONE
```
    no transformation is applied to values; server-side field value remains a Java List when passed to the execute(Fetch|Add|Update|Remove) method of the server-side DataSource class
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "none".

  - values
```
public static MultipleFieldStorage[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (MultipleFieldStorage c : MultipleFieldStorage.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static MultipleFieldStorage valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - getValue
```
public java.lang.String getValue()
```
    Specified by:
    
    getValue in interface ValueEnum
