public class XmlDataType
extends AbstractLengthDataType<Document>

The data associated with 'XML' values (Document). At the moment this class is empty, but of course we forsee the possibility for restrictions on doc-type.

Constructor Detail

XmlDataType

public XmlDataType(String name)

Constructor for xml data type.

Parameters:

name - the name of the data type

Method Detail

getLength

public long getLength(Object value)

Description copied from class: AbstractLengthDataType

In this method should be implemented how to calculate such a length for a certain value of this datatype. There does not exist a generic interface for this, so the implementation will cast to the expected type (String, byte[]..)

Specified by:

getLength in interface LengthDataType<Document>

Specified by:

getLength in class AbstractLengthDataType<Document>

castForSearch

public String castForSearch(Object value,
                            Node node,
                            Field field)

Description copied from interface: DataType

Sometimes the the representation of the value is a bit different in the database, or has a different type. So when constraining a search on the value, casting is done by this. This may default to DataType.cast(Object, Node, Field).

Specified by:

castForSearch in interface DataType<Document>

Overrides:

castForSearch in class BasicDataType<Document>
