Method Detail

getJavaType

public java.lang.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

getDefaultLengthAsString

protected int getDefaultLengthAsString()

Specified by:

getDefaultLengthAsString in class TemporalMapping

getSampleValue

public java.lang.Object getSampleValue(ClassLoaderResolver clr)

Description copied from class: JavaTypeMapping

Return a sample value of the mapping type to be used for internal evaluation of type/conversion. TODO Delete when we drop legacy support

Overrides:

getSampleValue in class JavaTypeMapping

Parameters:

clr - ClassLoader resolver

Returns:

The sample value.

newLiteral

public ScalarExpression newLiteral(QueryExpression qs,
                                   java.lang.Object value)

Description copied from class: JavaTypeMapping

Creates a literal from an value for use in TJDO-style JDOQL. This implementation just throws a NucleusException.

Overrides:

newLiteral in class JavaTypeMapping

Parameters:

qs - The Query statement

value - The object

Returns:

A Scalar Expression TODO Remove this when we drop legacy query mechanism
