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

Subclasses of BaseStep in org.apache.commons.workflow.base

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 BaseStep in org.apache.commons.workflow.core

Subclasses of BaseStep in org.apache.commons.workflow.core

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	BreakStep Locate the closest surrounding Iterator, set the nesting control to false, and transfer control to the Iterator.
class	CallStep Pop the top value from the evaluation stack, which must be an Activity, and initiate a "subroutine call" to execute this Activity before resuming the current one.
class	ConstructStep Create a new object of the specified class, using the constructor that accepts the arguments specified by the associated Descriptor objects.
class	ContinueStep Locate the closest surrounding Iterator, set the nesting control to true, and transfer control to the Iterator.
class	DuplicateStep Push a new copy of the top item on the evaluation stack onto the stack.
class	ExitStep Signal our Context that we have completed the current Activity.
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	LoadStep Load a class with the specified name from the specified class loader, and push the corresponding java.lang.Class object onto the evaluation stack.
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	PopStep Pop the top value from the evaluation stack and throw it away.
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	StringStep Push the specified String value onto the top of the evaluation stack.
class	SuspendStep Signal our Context to suspend execution until control is returned.
class	SwapStep Swap the positions of the top two values on the evaluation stack.
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.

Subclasses of BaseStep in org.apache.commons.workflow.io

class	DisplayStep For each associated Descriptor, print the value of the specified Java object to standard output.
class	GetStep Retrieve the contents of a specified URL resource, and push the contents as a String object onto the evaluation stack.
