Detailed Description

ShaderHandler serves files related to shaders, their dependencies, and the shader editor.

Shader-related pages have a proc-like structure. For example, if there are shaders shader1 and shader2 (with respective dependencies shader1_v_source, shader1_f_source, and shader2_v_source, shader2_f_source), are registered with the ShaderManager, then the following paths are valid (note that the paths are relative to the handler's root): / - List of shaders /shader1 - Lists info log and shader stages /shader1/|info log| - shader1's link info log /shader1/vertex - Lists dependencies and info log /shader1/vertex/|info log| - shader1's vertex shader info log /shader1/vertex/shader1_v_source - Text of shader1_v_source /shader1/fragment/|info log| - shader1's fragment shader info log /shader1/fragment/shader1_f_source - Text of shader1_f_source /shader2 - Lists info log and shader stages /shader2/|info log| - shader2's link info log /shader2/vertex - Lists dependencies and info log /shader2/vertex/|info log| - shader2's vertex shader info log /shader2/vertex/shader2_v_source - Text of shader2_v_source /shader2/fragment/|info log| - shader2's fragment shader info log /shader2/fragment/shader2_f_source - Text of shader2_f_source

/shader_editor serves the shader editor. It allows run-time editing of shaders by modifiying their dependencies directly. See the online help on the served page for more information.

const std::string ion::remote::ShaderHandler::HandleRequest	(	const std::string &	path,

	)

overridevirtual

The HandleRequest() function is passed the path (relative to its base path) of the file or directory to serve, and any query arguments associated with the request.

The handler should return an empty string if it cannot handle the request. The handler may optionally set a specific content type to be returned in the response headers. If the handler does not set a content type then a suitable one will be chosen based on the extension of the requested file.

Note: if a handler is registered to serve just a single filename then the path passed to it will be "", since that is the relative path from a file to itself.

Implements ion::remote::HttpServer::RequestHandler.
