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)
This callback method is invoked by the %New method to
provide notification that a new instance of an object is being created.
method GenerateCode(pCompiler As Ens.BPL.Compiler)
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 GenerateXML(pStream As %BinaryStream)
method Validate(ByRef pStatus As %Status, pContext As Ens.BPL.ValidationContext)
