public Message(Expression select, Expression terminate, Expression errorCode)
select
- the expression that constructs the message (composite of the select attribute
and the contained sequence constructor)terminate
- expression that calculates terminate = yes or no.errorCode
- expression used to compute the error codepublic Expression getSelect()
public void setSelect(Expression select)
public Expression getTerminate()
public void setTerminate(Expression terminate)
public Expression getErrorCode()
public void setErrorCode(Expression errorCode)
public java.lang.Iterable<Operand> operands()
Expression
If the expression is a Callable, then it is required that the order of the operands returned by this function is the same as the order of arguments supplied to the corresponding call() method.
