class Ens.BPL.Context
extends Ens.BPL.Node
is an object that is available to a BPL business process anywhere inside the element.
context is a general-purpose container for any data that needs to be persisted during the life cycle of
the business process. You define each data item as a property on the context object when creating the BPL
business process as follows in the example
• method %OnNew(initvalue As %RawString)
as %Status
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
• method GenerateXML(pStream As %BinaryStream)
as %Status
• method Validate(ByRef pStatus As %Status, pContext As Ens.BPL.ValidationContext)
as %Status
