public InterfaceMapping()

Method Details

initialize

public void initialize(org.datanucleus.metadata.AbstractMemberMetaData mmd,
 Table table,
 org.datanucleus.ClassLoaderResolver clr)

Initialisation.

Overrides:

initialize in class ReferenceMapping

Parameters:

mmd - MetaData for the field/property

table - datastore container (table)

clr - ClassLoader resolver

setImplementationClasses

public void setImplementationClasses(String implementationClasses)

Set the implementation classes. If the field defined what the implementation classes are, this mapping will only use it

Parameters:

implementationClasses - the implementation classes string

getObject

public Object getObject(org.datanucleus.ExecutionContext ec,
 ResultSet rs,
 int[] pos)

Method to retrieve an object of this type from the ResultSet.

Overrides:

getObject in class ReferenceMapping

Parameters:

ec - ExecutionContext

rs - The ResultSet

pos - The parameter positions

Returns:

The object
