Class ExecutionTrace

java.lang.Object

com.whitestein.lsps.engine.ExecutionTrace

All Implemented Interfaces:

Serializable

public final class ExecutionTrace
extends Object
implements Serializable

Object of this class is return value of ProcessAgent invocation. ExecutionTraceElement describe individual steps performed during the ProcessAgent invocation. For example, when ProcessAgent is invoked (by ProcessService.startInterpretModelInstance(long, boolean)) and interpretation of the model proceeds to some custom task, the custom task implementation can create new ExecutionTraceElement through which information relevant for caller may be passed. This approach is used to implement nextTodo mechanism. BaseTodoTask creates new ExecutionTraceElement (actually a subclass TodoExecutionTraceElement) with information about newly created todos.

Method Detail

addExecutionTraceElement

public void addExecutionTraceElement(ExecutionTraceElement ete)

Parameters:

ete - Adds new ExecutionTraceElement.

getExecutionTraceElements

public List<ExecutionTraceElement> getExecutionTraceElements()

Returns:

Returns list of ExecutionTraceElement which describes individual execution steps.

getFirstExecutionTraceElement

public <T extends ExecutionTraceElement> T getFirstExecutionTraceElement(Class<T> clazz)

Type Parameters:

T -

Parameters:

clazz -

Returns:

Returns first instance of ExecutionTraceElement of given type.

getLastExecutionTraceElement

public <T extends ExecutionTraceElement> T getLastExecutionTraceElement(Class<T> clazz)

Type Parameters:

T -

Parameters:

clazz -

Returns:
