end

public void end()

Ends the DSL.

isActive

public boolean isActive()

Returns true if the DSL has been started.

getKind

public ShaderKind getKind()

getOptions

isBuiltin

public boolean isBuiltin()

Returns:

true if we are at built-in level

isModule

public boolean isModule()

Returns:

true if we are processing include files

getTypes

public BuiltinTypes getTypes()

Returns the BuiltinTypes used by DSL operations in the current thread.

getSymbolTable

public SymbolTable getSymbolTable()

Returns the current SymbolTable.

 int end,
 String msg)

warning

 String msg)

warning

public void warning(int start,
 int end,
