Uses of Descriptors in org.apache.commons.workflow.base

Classes in org.apache.commons.workflow.base that implement Descriptors

class	BaseBlock BaseBlock is a convenient base class for more sophisticated Block implementations.
class	DescriptorStep DescriptorStep is a convenient base class for more sophisticated Step implementations that already support the APIs provided by BaseStep, and also implement the Descriptors interafce.

Uses of Descriptors in org.apache.commons.workflow.core

Classes in org.apache.commons.workflow.core that implement Descriptors

class	AndStep Evaluate properties specified by the associated Descriptors, and transfer control to the specified step if ALL of them are true (if boolean) or not null (if Object).
class	ConstructStep Create a new object of the specified class, using the constructor that accepts the arguments specified by the associated Descriptor objects.
class	GetStep For each associated Descriptor, make a copy of the specified Java object and push it on to the evaluation stack, in the order that descriptors are listed.
class	GotoStep Unconditionally transfer control to the specified step.
class	IfAnyStep Evaluate properties specified by the associated Descriptors, and execute the nested Steps if and only if ANY of them evaluate to a positive result.
class	IfNotAnyStep Evaluate properties specified by the associated Descriptors, and execute the nested Steps if and only if ALL of them evaluate to a negative result.
class	IfNotStep Evaluate properties specified by the associated Descriptors, and execute the nested Steps if and only if ANY of them evaluate to a negative result.
class	IfStep Evaluate properties specified by the associated Descriptors, and execute the nested Steps if and only if they ALL evaluate to a positive result.
class	InvokeStep Call the specified method of the specified bean in the specified scope, passing arguments as specified by associated Descriptor objects.
class	NotAndStep Evaluate properties specified by the associated Descriptors, and transfer control to the specified step if ALL of them are false (if boolean) or null (if Object).
class	NotOrStep Evaluate properties specified by the associated Descriptors, and transfer control to the specified step if ANY of them are false (if boolean) or null (if Object).
class	OrStep Evaluate properties specified by the associated Descriptors, and transfer control to the specified step if ANY of them are true (if boolean) or not null (if Object).
class	PutStep For each associated Descriptor, pop the top value from the evaluation stack, and store it as specified by that Descriptor, in the order that descriptors are listed.
class	RemoveStep For each associated Descriptor, remove the corresponding Java object from our Context, in the order that descriptors are listed.
class	WhileAnyStep Repeatedly evaluate the properties specified by the associated Descriptors, and execute the nested Steps if and only if ANY of them evaluate to a positive result.
class	WhileNotAnyStep Repeatedly evaluate the properties specified by the associated Descriptors, and execute the nested Steps if and only if ALL of them evaluate to a negative result.
class	WhileNotStep Repeatedly evaluate the properties specified by the associated Descriptors, and execute the nested Steps if and only if ANY of them evaluate to a negative result.
class	WhileStep Repeatedly evaluate the properties specified by the associated Descriptors, and execute the nested Steps if and only if ALL of them evaluate to a positive result.
