Ens.BPL.Scope

class Ens.BPL.Scope extends Ens.BPL.Activity

This class represents a sequence of activities to be performed. Errors occuring with the scope block are caught and redirected to the a fault handler. The fault handler can, if desired, invoke a compensation handler which is a named block of code which is intended to compensate for the fault. Transfer of control flow to a catch block can also be achieved by using the Throw activity,naming the catch block to be invoked.

Methods

private method %OnNew(initvalue As %RawString) as %Status [ Language = objectscript ]
Inherited description: This callback method is invoked by the %New() method to provide notification that a new instance of an object is being created.

If this method returns an error then the object will not be created.

It is passed the arguments provided in the %New call. When customizing this method, override the arguments with whatever variables and types you expect to receive from %New(). For example, if you're going to call %New, passing 2 arguments, %OnNew's signature could be:

Method %OnNew(dob as %Date = "", name as %Name = "") as %Status If instead of returning a %Status code this returns an oref and this oref is a subclass of the current class then this oref will be the one returned to the caller of %New method.

method GenerateCode(pCompiler As Ens.BPL.Compiler) as %Status [ Language = objectscript ]
method GenerateXML(pStream As %BinaryStream) as %Status [ Language = objectscript ]
