// Title: TLM Export Classes
//------------------------------------------------------------------------------
// The following classes define the TLM export classes.
//------------------------------------------------------------------------------


//------------------------------------------------------------------------------
//
// CLASS: uvm_*_export #(T)
//
// The unidirectional uvm_*_export is a port that ~forwards~ or ~promotes~
// an interface implementation from a child component to its parent.
// An export can be connected to any compatible child export or imp port.
// It must ultimately be connected to at least one implementation
// of its associated interface.
//
// The interface type represented by the asterisk is any of the following
//
//|  blocking_put
//|  nonblocking_put
//|  put
//|
//|  blocking_get
//|  nonblocking_get
//|  get
//|
//|  blocking_peek
//|  nonblocking_peek
//|  peek
//|
//|  blocking_get_peek
//|  nonblocking_get_peek
//|  get_peek
//
// Type parameters
//
// T - The type of transaction to be communicated by the export
// 
// Exports are connected to interface implementations directly via 
// <uvm_*_imp #(T,IMP)> ports or indirectly via other <uvm_*_export #(T)> exports.
//
//------------------------------------------------------------------------------


// Function: new
// 
// The ~name~ and ~parent~ are the standard <uvm_component> constructor arguments.
// The ~min_size~ and ~max_size~ specify the minimum and maximum number of
// interfaces that must have been supplied to this port by the end of elaboration.
//

//|                uvm_component parent,
//|                int min_size=1,
