DataTypeRegistry

public DataTypeRegistry(DataTypeRegistry parent)
                 throws DataTypeException

Parameters:

parent -

Throws:

DataTypeException

Method Detail

getDefaultRegistry

public static DataTypeRegistry getDefaultRegistry()

Get the default DataTypeRegistry containing the built-in data types.

Returns:

registerDataType

public DataType registerDataType(DataType dataType,
                                 boolean replaceExisting)
                          throws DataTypeException

Register a new DataType implementation into this registry.

Parameters:

dataType -

replaceExisting -

Returns:

Throws:

DataTypeException

deregisterDataType

public DataType deregisterDataType(DataType dataType)
                            throws DataTypeException

Remove the given DataType instance from this registry. Note that you cannot deregister data types from the default registry.

Parameters:

dataType -

Returns:

Throws:

DataTypeException

hasDataType

public boolean hasDataType(String id)

Search this registry (and its ancestors) looking for a data type with the given id.

Parameters:

id -

Returns:

getDataType

public DataType getDataType(String id)
                     throws DataTypeException

Get the DataType instance with the given id from this registry (or its ancestors).

Parameters:

id -

Returns:

Throws:

DataTypeException

getDataType

public DataType getDataType(String id,
                            String serializedVariantInfo,
                            ClassLoader loader)
                     throws DataTypeException

Get the DataType instance with the given id from this registry (or its ancestors) and create a new variant of the base data type using the provided serializedVariantInfo.

Parameters:

id -

serializedVariantInfo - Variant information obtained from a prior call to DataTypeVariantInfoSerializer.serializeVariantInfo()
