Constructor Detail

StandardExpressionObjectFactory

public StandardExpressionObjectFactory()

Method Detail

getAllExpressionObjectNames

public Set<String> getAllExpressionObjectNames()

Description copied from interface: IExpressionObjectFactory

Return the complete list of expression objects that can be created by this factory.

This list will be used for determining if a factory might actually be asked to build an object, so it should contain all possible objects to be built by the factory.

Specified by:

getAllExpressionObjectNames in interface IExpressionObjectFactory

Returns:

the list of objects this factory can build.

isCacheable

public boolean isCacheable(String expressionObjectName)

Description copied from interface: IExpressionObjectFactory

Returns whether a specific expression object can be cached and reused for all expressions in the same template execution or not.

Note this cacheable flag refers only to reuse of the object in expressions in expressions executed during a single template execution.

Specified by:

isCacheable in interface IExpressionObjectFactory

Parameters:

expressionObjectName - the name of the expression object.

Returns:

true is the object is to be considered cacheable, false if not.

buildObject

public Object buildObject(IExpressionContext context,
                          String expressionObjectName)

Description copied from interface: IExpressionObjectFactory

Build the requested object.

Specified by:

buildObject in interface IExpressionObjectFactory

Parameters:

context - the context being used for processing the template.

expressionObjectName - the name of the expression object to be built.

Returns:

the built object, or null if the object could not be built.
