Detailed Description

This is a specialization on Geom for containing a primitive intended to represent a TextGlyph.

Its sole purpose is to maintain the geom count on the glyph, so we can determine the actual usage count on a dynamic glyph (and thus know when it is safe to recycle the glyph).

Definition at line 27 of file geomTextGlyph.h.

Member Function Documentation

◆ add_glyph()

void GeomTextGlyph::add_glyph ( const TextGlyph * glyph )

Adds a glyph to the list of glyphs referenced by this Geom.

Definition at line 178 of file geomTextGlyph.cxx.

◆ copy_primitives_from()

bool GeomTextGlyph::copy_primitives_from ( const Geom * other )

virtual

Copies the primitives from the indicated Geom into this one.

This does require that both Geoms contain the same fundamental type primitives, both have a compatible shade model, and both use the same GeomVertexData. Both Geoms must also be the same specific class type (i.e. if one is a GeomTextGlyph, they both must be.)

Returns true if the copy is successful, or false otherwise (because the Geoms were mismatched).

Reimplemented from Geom.

Definition at line 107 of file geomTextGlyph.cxx.

References Geom::copy_primitives_from().

◆ count_geom()

void GeomTextGlyph::count_geom ( const Geom * other )

Records the reference count of the other Geom within this Geom, as if the primitives were copied in via copy_primitives_from() (but does not actually copy any primitives).

This is particularly necessary for GeomTextGlyph's reference counting mechanism.

Does nothing if the other Geom is not a GeomTextGlyph.
