public class StatementExecution

extends java.lang.Object

The class used to define a template transformation's program.

See Also:

A StatementExecution object is used to define the statement that is going to be invoked during a template transformation's execution at a specific time in the execution (program counter) and the sequence of arguments that is going to be used for the statement's invocation. StatementExecution objects can be created through a CompositeTransformation object.

protected static java.util.ArrayList	getStatementExecutionsForTransformation(int transId) Returns all the StatementExecution objects of the specified composite transformation.
int	getTransId() Returns the transformation identifier of the composite transformation this StatementExecution belongs to.
void	print()
protected void	remove() Removes this StatementExecution from the TTR.
void	setArgumentSequence(TemplateArgumentSequence args) Sets the TemplateArgumentSequence of this StatementExecution
void	setStatement(Statement stmnt) Sets the Statement of this StatementExecution.
