ps - The Prepared Statement

param - Param numbers in the PreparedStatement for this object

value - The OID value to use

getObject

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

Accessor for the OID object from the result set

Overrides:

getObject in class SingleFieldMapping

Parameters:

ec - ExecutionContext managing this object

rs - The ResultSet

param - Array of param numbers for this object

Returns:

The OID object

getJavaType

public Class getJavaType()

Description copied from class: JavaTypeMapping

Accessor for the java type being mapped. This is the java type that the mapping represents. Some examples :

• if the field is of type "MyClass" then the mapping will be OIDMapping (or subclass) the javaType will be OID, and the type will be MyClass.
• if the field is of type "int" then the mapping will be IntegerMapping, the javaType will be Integer, and the type will be int.

The "java type" is the java-type name used in the plugin.xml mapping file

Specified by:

getJavaType in class JavaTypeMapping

Returns:

The java type
