class ToolViewsVisible  from IGESDraw

    ---Purpose : Tool to work on a ViewsVisible. Called by various Modules
    --           (ReadWriteModule, GeneralModule, SpecificModule)

uses ViewsVisible from IGESDraw,
     IGESReaderData, ParamReader, IGESWriter, EntityIterator,
     DirChecker,     ShareTool,   Check,      CopyTool,   IGESDumper, Messenger from Message

raises DomainError

is

    Create returns ToolViewsVisible;
    ---Purpose : Returns a ToolViewsVisible, ready to work


    ReadOwnParams (me; ent : mutable ViewsVisible;
    	    	   IR : IGESReaderData; PR : in out ParamReader)
    	raises DomainError  is static;
    ---Purpose : Reads own parameters from file. <PR> gives access to them,
    --           <IR> detains parameter types and values

    WriteOwnParams (me; ent : ViewsVisible;
    	    	    IW : in out IGESWriter)  is static;
    ---Purpose : Writes own parameters to IGESWriter


    OwnShared  (me; ent : ViewsVisible;
    	        iter : in out EntityIterator)  is static;
    ---Purpose : Lists the Entities shared by a ViewsVisible <ent>, from
    --           its specific (own) parameters shared not implied (the Views)

    OwnImplied (me; ent : ViewsVisible;
    	        iter : in out EntityIterator)  is static;
    ---Purpose : Lists the Entities shared by a ViewsVisible <ent>, from
    --           its specific (own) implied parameters : the Displayed Entities


    DirChecker (me; ent : ViewsVisible) returns DirChecker  is static;
    ---Purpose : Returns specific DirChecker

    OwnCheck   (me; ent : ViewsVisible;
    	        shares  : ShareTool; ach : in out Check)  is static;
    ---Purpose : Performs Specific Semantic Check


    OwnCopy    (me; entfrom : ViewsVisible; entto : mutable ViewsVisible;
    	        TC : in out CopyTool)  is static;
    ---Purpose : Copies Specific Parameters shared not implied, i.e. all but
    --           the Displayed Entities

    OwnRenew   (me; entfrom : ViewsVisible; entto : mutable ViewsVisible;
    	        TC : CopyTool)  is static;
    ---Purpose : Copies Specific implied Parameters : the Displayed Entities
    --           which have already been copied

    OwnWhenDelete (me; ent : ViewsVisible)  is static;
    ---Purpose : Clears specific implied parameters, which cause looping
    --           structures; required for deletion


    OwnDump (me; ent : ViewsVisible;
    	     dumper  : IGESDumper;  S : Messenger from Message; own : Integer)
        is static;
    ---Purpose : Dump of Specific Parameters

    OwnCorrect (me; ent : mutable ViewsVisible) returns Boolean is static;
    ---Purpose : Sets automatic unambiguous Correction on a ViewsVisible
    --           (all displayed entities must refer to <ent> in directory part,
    --           else the list is cleared)
