DSOperationType (Smart GWT EE API 14.0p (2026-01-20))

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

All Implemented Interfaces:

ValueEnum, java.io.Serializable, java.lang.Comparable<DSOperationType>
```
public enum DSOperationType
extends java.lang.Enum<DSOperationType>
implements ValueEnum
```
One of the four basic operations that can be performed on DataSource data: "fetch", "add", "update", "remove". Elsewhere called CRUD operations, where CRUD stands for "create", "retrieve", "update", "delete", which correspond to "add", "fetch", "update" and "remove" in Smart GWT terminology. See DataSourceOperations for a full description.
There are also additional, non-CRUD operations explained below.

Enum Constant Summary

Enum Constant and Description
`ADD` Store new records
`CLIENTEXPORT` Upload formatted client data and export it to Excel, XML and other formats.
`CUSTOM` perform some arbitrary custom logic that is not a CRUD operation.
`DOWNLOADFILE` Like "viewFile", but the HTTP header Content-Disposition is used to suggest that the browser show a save dialog.
`FETCH` Fetch one or more records that match a set of search criteria.
`GETFILE` Use the DataSource as a `source for files`.
`GETFILEVERSION` Use the DataSource as a `source for files`.
`HASFILE` Use the DataSource as a `source for files`.
`HASFILEVERSION` Use the DataSource as a `source for files`.
`LISTFILES` Use the DataSource as a `source for files`.
`LISTFILEVERSIONS` Use the DataSource as a `source for files`.
`REMOVE` Remove (delete) an existing record
`REMOVEFILE` Use the DataSource as a `source for files`.

`SAVEFILE` Use the DataSource as a `source for files`.
`STORETESTDATA` Takes a List of Maps and stores the data in Admin Console XML test data format
`UPDATE` Update an existing record
`VALIDATE` Run server-side validation for "add" or "update" without actually adding or updating anything.
`VIEWFILE` Retrieve a file stored in a binary field in a DataSource record, and allow the browser to choose whether to view it directly or prompt the user to save.

- Enum Constant Detail
  - FETCH
```
public static final DSOperationType FETCH
```
    Fetch one or more records that match a set of search criteria.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "fetch".
  - ADD
```
public static final DSOperationType ADD
```
    Store new records
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "add".

```
public static final DSOperationType UPDATE
```

```
public static final DSOperationType REMOVE
```
    Remove (delete) an existing record
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "remove".
  - CUSTOM
```
public static final DSOperationType CUSTOM
```
    perform some arbitrary custom logic that is not a CRUD operation. Format of the inputs and outputs is unconstrained, and the operation will be ignored for cache sync purposes by ResultSets. See DataSource.performCustomOperation().
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "custom".
  - VALIDATE
```
public static final DSOperationType VALIDATE

    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "validate".
  - VIEWFILE
```
public static final DSOperationType VIEWFILE
```
    Retrieve a file stored in a binary field in a DataSource record, and allow the browser to choose whether to view it directly or prompt the user to save. See BinaryFields.

  - DOWNLOADFILE
```

```
public static DSOperationType[] 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:

  - valueOf
```
public static DSOperationType 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
