Method Detail

getInstance

public static CharArrayValueHandler getInstance()
Singleton instance.


map

public Column[] map(ValueMapping vm,
                    String name,
                    ColumnIO io,
                    boolean adapt)
Deprecated. 

Description copied from interface: ValueHandler
Map the given value and return all mapped columns, or simply return an array of unmapped default columns. The columns should have at least their Name and JavaType properties set.

name - use as a base to form column name(s); the column names of unmapped columns will automatically be made to fit database limitations
io - I/O information about mapped columns; you do not have to set this information if returning templates
adapt - whether to adapt the mapping or schema

map

public Column[] map(ValueMapping vm,
                    DBIdentifier name,
                    ColumnIO io,
                    boolean adapt)

toDataStoreValue

public Object toDataStoreValue(ValueMapping vm,
                               Object val,
                               JDBCStore store)
Description copied from interface: ValueHandler
Translate the given value to its datastore equivalent. If this value occupies multiple columns, return an object array with one element per column. For relation id columns, return the state manager the column depends on.

Specified by:
toDataStoreValue in interface ValueHandler
Overrides:
toDataStoreValue in class AbstractValueHandler

toObjectValue

public Object toObjectValue(ValueMapping vm,
                            Object val)
Description copied from interface: ValueHandler
Translate the given datastore value into its Java equivalent. If the value occupies multiple columns, the given object will be an object array with one entry per column. This method is only called if ValueHandler.objectValueRequiresLoad(org.apache.openjpa.jdbc.meta.ValueMapping) returns false.

Specified by:
toObjectValue in interface ValueHandler
Overrides:
toObjectValue in class AbstractValueHandler
