Method Detail

setSourceMap

public void setSourceMap(Map sourceMap)

Set the source Map, typically populated via XML "map" elements.

setTargetMapClass

public void setTargetMapClass(Class targetMapClass)

Set the class to use for the target Map. Can be populated with a fully qualified class name when defined in a Spring application context.

Default is a linked HashMap, keeping the registration order. If no linked Map implementation is available, a plain HashMap will be used as fallback (not keeping the registration order).

getObjectType

public Class getObjectType()

Description copied from class: AbstractFactoryBean

This abstract method declaration shadows the method in the FactoryBean interface. This is necessary to make the getEarlySingletonInterfaces implementation in this class work on Sun's JDK 1.3 classic VM, which can't find the method when executing getEarlySingletonInterfaces else.

Specified by:

getObjectType in interface FactoryBean

Specified by:

getObjectType in class AbstractFactoryBean

Returns:

the type of object that this FactoryBean creates, or null if not known at the time of the call

See Also:

FactoryBean.getObjectType(), AbstractFactoryBean.getEarlySingletonInterfaces()

createInstance

protected Object createInstance()

Description copied from class: AbstractFactoryBean

Template method that subclasses must override to construct the object returned by this factory.

Invoked on initialization of this FactoryBean in case of a singleton; else, on each AbstractFactoryBean.getObject() call.

Specified by:

createInstance in class AbstractFactoryBean

Returns:

the object returned by this factory

AbstractFactoryBean.getObject()
