getObjectType

public java.lang.Class<java.util.Map> getObjectType()

Description copied from class: AbstractFactoryBean

This abstract method declaration mirrors the method in the FactoryBean interface, for a consistent offering of abstract template methods.

Specified by:

getObjectType in interface FactoryBean<java.util.Map<java.lang.Object,java.lang.Object>>

Specified by:

getObjectType in class AbstractFactoryBean<java.util.Map<java.lang.Object,java.lang.Object>>

Returns:

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

See Also:

FactoryBean.getObjectType()

createInstance

protected java.util.Map<java.lang.Object,java.lang.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<java.util.Map<java.lang.Object,java.lang.Object>>

Returns:

the object returned by this factory
