Methods
Modifier and Type	Method and Description

`java.lang.String`	`getFieldId(java.lang.Enum<?> value)` Return the field name for a given enum value.
`java.lang.String`	`getFieldId(java.lang.String className, java.lang.String fieldName)` This is similar to `ClientOracle.getFieldId(Class, String)` but does not search supertypes.

    Specified by:
    
    createCommandSink in class ClientOracle
    
    Parameters:
    out - the OutputStream to which the output will be written
    
    Returns:
    a CommandSink
    
    Throws:
    
    java.io.IOException - if the CommandSink cannot write to the OutputStream

  - getCastableTypeData
```
public CastableTypeData getCastableTypeData(java.lang.Class<?> clazz)
```
    Description copied from class: ClientOracle

                          java.lang.String fieldName)
```
    Description copied from class: ClientOracle
    
    Given a base type and the unobfuscated field name, find the obfuscated name for the field in the client. This will search superclasses as well for the first matching field.
    
    Specified by:
    
    getFieldId in class ClientOracle
  - getFieldId
```
public java.lang.String getFieldId(java.lang.Enum<?> value)
```
    Description copied from class: ClientOracle
    
    Return the field name for a given enum value.
    
    Specified by:

```
    Description copied from class: ClientOracle
    
    This is similar to ClientOracle.getFieldId(Class, String) but does not search supertypes. It is intended to be used to access "magic" GWT types.
    
    Specified by:
    
    getFieldId in class ClientOracle
  - getFieldName
```
