-- Description: Wave option file child package for reading the tree created
-- after parsing the wave option file. It provides functions to
-- find in the tree which signals are to be displayed or not
with Grt.Types; use Grt.Types;
package Grt.Wave_Opt_File.Tree_Reading is
pragma Preelaborate;
-- Returns the top element of the tree corresponding to the index given, but
-- only if the name given matches with it. Otherwise returns null
function Get_Top_Cursor (Name : Ghdl_C_String; Index : Tree_Index_Type)
return Elem_Acc;
-- If there is an element in the parent element given that match the name
-- given, returns it, otherwise returns null
function Get_Cursor
(Name : Ghdl_C_String; Parent : Elem_Acc; Is_Signal : Boolean := False)
return Elem_Acc;
-- Returns true if the element given is not null, which means it exists in
-- the tree of the VHDL elements to be displayed
function Is_Displayed (Cursor : Elem_Acc) return Boolean;
-- Read the whole tree and check if every element was found in design
procedure Check_If_All_Found;
end Grt.Wave_Opt_File.Tree_Reading;
