Definition at line 396 of file shadersourcecomposer.cc.

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.

const std::vector< std::string > ion::gfxutils::IncludeComposer::GetChangedDependencies ( )

overridevirtualinherited

Determines if any dependencies have changed (e.g., if a file has changed on disk since the last call to Get(Source|DependencySource)()) and updates them.

Returns a vector containing the names of the dependencies that have changed.

Implements ion::gfxutils::ShaderSourceComposer.

Definition at line 378 of file shadersourcecomposer.cc.

const std::string ion::gfxutils::IncludeComposer::GetDependencyName ( unsigned int id ) const

overridevirtualinherited

Returns the name of a dependency identified by the passed id.

The id is an integral value used by OpenGL to identify a shader file. Returns an empty string if the id is unknown or if there are no dependencies.

Implements ion::gfxutils::ShaderSourceComposer.

Definition at line 400 of file shadersourcecomposer.cc.

const std::vector< std::string > ion::gfxutils::IncludeComposer::GetDependencyNames ( ) const

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

inlineinherited

Windows requires these (or it issues C4291 warnings).

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,

inlineinherited

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

	)

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.

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