Return true if a field of my type can be assigned the given non-null value, false otherwise.

Specified by:

accepts in interface DataType

Specified by:

accepts in class BaseDataType

Parameters:

value - non-null value

supportsSuccessor

public boolean supportsSuccessor()

Description copied from interface: DataType

Returns true if the DataType.successor(java.lang.Object)method is supported, false otherwise.

Specified by:

supportsSuccessor in interface DataType

Overrides:

supportsSuccessor in class BaseDataType

successor

public Object successor(Object value)
                 throws IllegalArgumentException
