Method Detail

addExecutionEntity

public void addExecutionEntity(ExecutionEntity entity)

Adds an ExecutionEntity in the list of entities to be executed

Parameters:

entity - the ExecutionEntity to add

initialize

public void initialize(Element xml,
                       BootstrappingConfiguration conf)
                throws Exception

Sets the execution entities contained inside this ExecutionType object. The entities are given in the form of an XML document fragment, which is parsed and transformed to objects.

Parameters:

xml - the XML describing the execution entities wrapped into this ExecutionType

conf - the active BootstrappingConfiguration object

Throws:

Exception

getEntitiesToBeExecuted

public List<ExecutionEntity> getEntitiesToBeExecuted()

Returns the list of ExecutionEntitys contained in this ExecutionType

Returns:

the list of entities to be executed by this ExecutionType

evaluate

public EvaluationResult evaluate(String expression)

Description copied from class: ExecutionEntity

Evaluates the given expression on the execution tree rooted at the current object and returns a Node representing the result

Specified by:

evaluate in interface Evaluable

Specified by:

evaluate in class ExecutionEntity

Parameters:

expression - the expression to evaluate, in "a.b.c..." notation

Returns:

the Node object that represents the result

initializeWithDataInScope

public void initializeWithDataInScope(org.gcube.common.core.scope.GCUBEScope scope)
                               throws Exception

Description copied from class: ExecutionEntity

Finds the DataTypes that could be possibly used as inputs for this entity as well as each sub-entity contained in it. The possible inputs for each entity are stored in a list inside the entity itself, so this method does not need to return anything. Furthermore, this method checks if the desirable output of this entity already exists in the given scope, and if it does, the entity's goal is defined as being already 'fulfilled' (the entity does not need to be executed).

Specified by:

initializeWithDataInScope in class ExecutionEntity

Parameters:

scope - the scope in which the entity will be executed

Throws:

Exception

cancel

public void cancel()

Description copied from class: ExecutionEntity

Cancels the execution of this execution entity. If the entity is not currently executing, calling this method has no effect.

Specified by:

cancel in class ExecutionEntity

clone

public Object clone()
             throws CloneNotSupportedException

Overrides:

clone in class ExecutionEntity

Throws:

CloneNotSupportedException
