public DateMapping()
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 : 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
