class ExternalRefFileIndex from IGESBasic  inherits IGESEntity

        ---Purpose: defines ExternalRefFileIndex, Type <402> Form <12>
        --          in package IGESBasic
        --          Contains a list of the symbolic names used by the
        --          referencing files and the DE pointers to the
        --          corresponding definitions within the referenced file

uses

        HAsciiString from TCollection,
        HArray1OfHAsciiString     from Interface,
        HArray1OfIGESEntity from IGESData

raises DimensionMismatch, OutOfRange

is

        Create returns mutable ExternalRefFileIndex;

        -- Specific Methods pertaining to the class

        Init (me : mutable; aNameArray : HArray1OfHAsciiString;
              allEntities : HArray1OfIGESEntity)
        raises DimensionMismatch;
        ---Purpose : This method is used to set the fields of the class
        --           ExternalRefFileIndex
        --       - aNameArray  : External Reference Entity symbolic names
        --       - allEntities : External Reference Entities
        -- raises exception if array lengths are not equal
        -- if size of aNameArray is not equal to size of allEntities

        NbEntries (me) returns Integer;
        ---Purpose : returns number of index entries

        Name (me; Index : Integer) returns HAsciiString from TCollection
        raises OutOfRange;
        ---Purpose : returns the External Reference Entity symbolic name
        -- raises exception if Index <= 0 or Index > NbEntries()

        Entity (me; Index : Integer) returns IGESEntity
        raises OutOfRange;
        ---Purpose : returns the internal entity
        -- raises exception if Index <= 0 or Index > NbEntries()
