TXFAHostTransport

Unit: HPDFXFAHost

Declaration

TXFAHostTransport= function(const Request: TXFAHostRequest;
  out Response: TXFAHostResponse; out Diagnostic: string): Boolean of object;

Behavior

The application implements this synchronous callback to perform or stage an explicit host request and return its typed response

Return False with Diagnostic to reject the request; exceptions also fail the enclosing document transaction

A dispatched request participates in failure completion even when the callback rejects, throws or returns an invalid response

Do not reenter the runtime or mutate its document from this callback
