Method Detail

close

public void close()
Description copied from interface: Generator
Closes the generator. After invocation the state is unavailable.

Specified by:
close in interface java.io.Closeable
Specified by:
close in interface Generator<E>
Overrides:
close in class AbstractGenerator<E>

generate

public ProductWrapper<E> generate(ProductWrapper<E> wrapper)
Description copied from interface: Generator
Returns an instance of the generic type E, using the ProductWrapper instance provided as argument. The wrapper may wrap a null value as a regular generator product. If the generator is not available (any more), it returns null instead of the ProductWrapper instance.


getGeneratedType

public java.lang.Class<E> getGeneratedType()
Description copied from interface: Generator
Declares the type of the objects returned by the generate() method.


init

public void init(GeneratorContext context)
          throws InvalidGeneratorSetupException
Specified by:
init in interface Generator<E>
Overrides:
init in class AbstractGenerator<E>
Throws:
InvalidGeneratorSetupException

reset

public void reset()
Specified by:
reset in interface org.databene.commons.Resettable
Overrides:
reset in class AbstractGenerator<E>

toString

public java.lang.String toString()
Overrides:
