Instance Methods¶

initialize( renderer, instance )¶

@public @override

@param {number} renderer @param {Instance} instance

createPainter()¶

Creates an instance of our Node's "painter" type. @private

@returns {*} - Whatever node.painterType is will be the type.

onWebGLContextChange()¶

Callback for when the WebGL context changes. We'll reconstruct the painter. @public

onAddToBlock( webGLBlock )¶

@public

@param {WebGLBlock} webGLBlock

onRemoveFromBlock( webGLBlock )¶

draw()¶

dispose()¶

Disposes the drawable. @public @override

markPaintDirty()¶

A "catch-all" dirty method that directly marks the paintDirty flag and triggers propagation of dirty information. This can be used by other mark* methods, or directly itself if the paintDirty flag is checked. @public

It should be fired (indirectly or directly) for anything besides transforms that needs to make a drawable dirty.
