		const ion::gfx::ShaderInputRegistryPtr &	registry,
		const ShaderSourceComposerPtr &	vertex_source_composer,
		const ShaderSourceComposerPtr &	fragment_source_composer
	)

Creates and returns a ShaderProgram with the passed name using the passed composers and registry.

References ion::base::Allocatable::GetAllocatorForLifetime(), and ion::base::kMediumTerm.

const AllocatorPtr& ion::base::Allocatable::GetAllocator ( ) const

inlineinherited

Returns the Allocator that was used for the instance.

This will be NULL if the instance was declared on the stack or created with normal placement new.

Convenience function that returns the Allocator to use to allocate an object with a specific lifetime.

Return our allocator, or the default allocator if the instance was declared on the stack.

int ion::base::Shareable::GetRefCount ( ) const

inlineinherited

GetRefCount() is part of the interface necessary for SharedPtr.

Referenced by ion::base::Notifier::RemoveReceiver().

const ShaderProgramPtr ion::gfxutils::ShaderManager::GetShaderProgram ( const std::string & name )

Returns a ReferentPtr to a ShaderProgram that has the passed name.

If no program with the passed name exists, returns a NULL ShaderProgramPtr.

Definition at line 208 of file shadermanager.cc.

void ion::gfxutils::ShaderManager::GetShaderProgramComposers	(	const std::string &	name,
		ShaderSourceComposerPtr *	vertex_source_composer,
		ShaderSourceComposerPtr *	fragment_source_composer
	)

Gets the composers used to construct the named program's shaders.

Either of the passed pointers may be NULL. If the named program does not exist then the passed composers will be set to NULL.

Definition at line 217 of file shadermanager.cc.

const std::vector< std::string > ion::gfxutils::ShaderManager::GetShaderProgramNames ( )

Gets a vector of the names of the shader programs created through the manager.

Definition at line 213 of file shadermanager.cc.

void ion::base::Allocatable::operator delete ( void * ptr )

inlineinherited

Define the delete operator to use specialized functions dealing with an Allocator.

Definition at line 109 of file allocatable.h.

void ion::base::Allocatable::operator delete	(	void *	ptr,
		AllocationLifetime	lifetime
	)

inlineinherited

Windows requires these (or it issues C4291 warnings).

Definition at line 112 of file allocatable.h.

void ion::base::Allocatable::operator delete	(	void *	ptr,
		const AllocatorPtr &	allocator
	)

inlineinherited

Definition at line 113 of file allocatable.h.

void ion::base::Allocatable::operator delete	(	void *	ptr,
		void *	ptr2
	)

inlineinherited

The placement delete operator does nothing, as usual.

Definition at line 118 of file allocatable.h.

void* ion::base::Allocatable::operator new ( size_t size )

inlineinherited

The standard no-parameter new operator uses the default Allocator.

Definition at line 84 of file allocatable.h.

void* ion::base::Allocatable::operator new	(	size_t	size,
		AllocationLifetime	lifetime
	)

inlineinherited

This overloaded version of the new operator uses the AllocationManager's default Allocator for the specified lifetime.

Definition at line 88 of file allocatable.h.

void* ion::base::Allocatable::operator new	(	size_t	size,
		const AllocatorPtr &	allocator
	)

inlineinherited

This overloaded version of the new operator takes the Allocator to use directly as a parameter.

If the Allocator pointer is NULL, this uses the default Allocator.

Definition at line 95 of file allocatable.h.

void* ion::base::Allocatable::operator new	(	size_t	size,
		const AllocatorPtr &	allocator,
		void *	ptr
	)

inlineinherited

Special operator new for using placement new with Allocatables.

Definition at line 100 of file allocatable.h.

void* ion::base::Allocatable::operator new	(	size_t	size,
		void *	ptr
	)

inlineinherited

The placement new operator is defined conventionally.

void ion::gfxutils::ShaderManager::RecreateAllShaderPrograms ( )

Reconstructs all shaders from their composers.

Definition at line 225 of file shadermanager.cc.

void ion::gfxutils::ShaderManager::RecreateShaderProgramsThatDependOn ( const std::string & dependency )

Reconstructs all shaders that depend on the named dependency.

The passed dependency name could be a filename or some other identifier that a ShaderSourceComposer will recognize.
