public abstract class BuiltIn
extends DataTypeImpl
implements BuiltInDataType

NOTE: ALL DATATYPE CLASSES MUST END IN "DataType". If not, the ClassSearcher will not find them. Base class for built-in Datatypes. A built-in data type is searched for in the classpath and added automatically to the available data types in the data type manager. NOTE: Settings are immutable when a DataTypeManager has not been specified (i.e., null).

isEquivalent

public boolean isEquivalent(DataType dt)

Description copied from interface: DataType

Check if the given datatype is equivalent to this datatype.

The precise meaning of "equivalent" is datatype dependent.

Description copied from interface: DataType

Set the categoryPath associated with this datatype

Specified by:

setCategoryPath in interface DataType

Overrides:

setCategoryPath in class AbstractDataType

Parameters:

path - the new path

Throws:

DuplicateNameException - if an attempt to place this datatype into the specified category resulted in a name collision. This should not occur for non-DB DataType instances.

setName

public final void setName(String name)
                   throws InvalidNameException

Description copied from interface: DataType

Sets the name of the datatype

Specified by:

setName in interface DataType

Overrides:

setName in class AbstractDataType

Parameters:

name - the new name for this datatype.

Throws:

InvalidNameException - if the given name does not form a valid name.

Specified by:

setNameAndCategory in interface DataType

Overrides:

setNameAndCategory in class AbstractDataType

Parameters:

path - the new category path.
