static SyntaxPtr GlslSyntax::create ( )

inlinestatic

Definition at line 24 of file GlslSyntax.h.

const string& GlslSyntax::getConstantQualifier ( ) const

inlineoverridevirtual

Get the qualifier used when declaring constant variables. Derived classes must define this method.

Implements Syntax.

Definition at line 28 of file GlslSyntax.h.

const string& GlslSyntax::getInputQualifier ( ) const

inlineoverridevirtual

Returns a type qualifier to be used when declaring types for input variables. Default implementation returns empty string and derived syntax classes should override this method.

Reimplemented from Syntax.

Reimplemented in VkSyntax.

Definition at line 26 of file GlslSyntax.h.

const string& GlslSyntax::getOutputQualifier ( ) const

inlineoverridevirtual

Returns a type qualifier to be used when declaring types for output variables. Default implementation returns empty string and derived syntax classes should override this method.

Reimplemented from Syntax.

Definition at line 27 of file GlslSyntax.h.

const string& GlslSyntax::getSourceFileExtension ( ) const

inlineoverridevirtual

Return the file extension used for source code files in this language.

Implements Syntax.

Definition at line 30 of file GlslSyntax.h.

const string& GlslSyntax::getUniformQualifier ( ) const

inlineoverridevirtual

Get the qualifier used when declaring uniform variables. Default implementation returns empty string and derived syntax classes should override this method.

Reimplemented from Syntax.

Definition at line 29 of file GlslSyntax.h.

bool GlslSyntax::remapEnumeration	(	const string &	value,
		const TypeDesc *	type,
		const string &	enumNames,
		std::pair< const TypeDesc *, ValuePtr > &	result
	)		const

overridevirtual

Given an input specification attempt to remap this to an enumeration which is accepted by the shader generator. The enumeration may be converted to a different type than the input.

Reimplemented from Syntax.

bool GlslSyntax::typeSupported ( const TypeDesc * type ) const

overridevirtual

Query if given type is suppored in the syntax. By default all types are assumed to be supported.

Reimplemented from Syntax.
