Detailed Description

Cache and reuse program object.

Member Function Documentation

destroyInstance()

void destroyInstance ( )

static

purges the cache.

It releases the retained instance.

registerCustomProgram()

uint64_t registerCustomProgram	(	std::string_view	vsName,
		std::string_view	fsName,
		VertexLayoutKind	vlk = VertexLayoutKind::Invalid,
		bool	force = false )

register a custom program

Returns

the id of custom program, 0: fail, the id can use by loadProgram

loadProgram() [1/2]

Program * loadProgram

(

uint64_t

progId

)

load a builtin/or custom program:

Parameters

id	the id of program to load, the id value returned by registerCustomProgram or builtin programType, whe the id < ProgramType:BUILTIN_COUNT, this function is identical to 'getBuiltinProgram'

loadProgram() [2/2]

Program * loadProgram	(	std::string_view	vsName,
		std::string_view	fsName,
		VertexLayoutKind	vlk = VertexLayoutKind::Invalid )

Load a program with vsName, fsName as CUSTOM immediately without register.

Parameters

vsName	the vertex shader name: custom/xxx_vs
fsName	the fragment shader name: custom/xxx_vs
vlk	the builtin vertex layout type used for loading program

Returns

Program* (nullable)

Remarks

the returend program type always ProgramType::CUSTOM_PROGRAM

unloadProgram()

void unloadProgram

(

Program *

program

)

Unload a program object from cache.

Parameters

program

Specifies the program object to move.
