class gxp.plugins.TMSSource(config)

Plugin for using TMS layers with gxp.Viewer instances. The plugin issues a Capabilities request to create a store of the TMS’s tile maps. It is currently not supported to use this source type directly in the viewer config, it is only used to add a TMS service dynamically through the AddLayers plugin.
