Get the IDL type for a particular element within a CORBA object's IDL interface.

Usage

idlElementType(server, element)

Arguments

server A CORBA object - either (nested) name or IOR - or the (fully qualified) name of an IDL interface
element the name of the element of interest within the IDL interface - an attribute or operation.

Description

This indicates whether the IDL interface of the CORBA object or identified specifically by name is an operation, an attribute or something else including non-existant. This can be used

Details

If a CORBA object is specified, either by name or explicitly by an IOR, the interface it implements is queried. If no such object is found, we assume the identifier is the name of the IDL interface. At this point, we query the Interface Repository for the IDL interface corresponding to this name and lookup the element within it. Its type is available to the C++ code from the object returned to us by the repository.

Value

If the element in the interface is an operation, the value 2 is returned. If it is an attribute, the value 1 is returned. Otherwise, -1 is returned.

Note

This is used in S when we try to handle the syntactically convenient server$name and we do not know whether this will be followed by a () or not. Hence, if name refers to an attribute, we want to evaluate it and retrieve the attribute's value. Otherwise, we create a reference to the function so that when it is invoked, it turns into an appropriate call to .Corba.

  # Ask about the element "sleep" in the
  # interface directly.
 idlElementType("RSExamples::Sleep","sleep")

  # Now try it on a server object that implements this.

 idlElementType("Sleeper","sleep")
