Detailed Description

A single parameter index whose accessors require each use to make explicit the parameter index encoding needed.

Member Typedef Documentation

SerialType

typedef uint32_t clang::ParamIdx::SerialType

A type into which ParamIdx can be serialized.

A static assertion that it's of the correct size follows the ParamIdx class definition.

Constructor & Destructor Documentation

ParamIdx() [1/2]

clang::ParamIdx::ParamIdx ( )

inline

Construct an invalid parameter index (isValid returns false and accessors fail an assert).

Definition at line 272 of file Attr.h.

ParamIdx() [2/2]

clang::ParamIdx::ParamIdx ( unsigned  Idx, const Decl *  D  )

inline

Parameters

Idx	is the parameter index as it is normally specified in attributes in the source: one-origin including any C++ implicit this parameter.
D	is the declaration containing the parameters. It is used to determine if there is a C++ implicit this parameter.

deserialize()

static ParamIdx clang::ParamIdx::deserialize ( SerialType  S )

inlinestatic

Construct from a result from serialize.

getASTIndex()

unsigned clang::ParamIdx::getASTIndex ( ) const

inline

Get the parameter index as it would normally be encoded at the AST level of representation: zero-origin not including any C++ implicit this parameter.

This is the encoding primarily used in Sema. However, in diagnostics, Sema uses getSourceIndex instead.

getLLVMIndex()

unsigned clang::ParamIdx::getLLVMIndex ( ) const

inline

Get the parameter index as it would normally be encoded at the LLVM level of representation: zero-origin including any C++ implicit this parameter.

This is the encoding primarily used in CodeGen.

Definition at line 340 of file Attr.h.

References isValid().

getSourceIndex()

unsigned clang::ParamIdx::getSourceIndex ( ) const

inline

Get the parameter index as it would normally be encoded for attributes at the source level of representation: one-origin including any C++ implicit this parameter.

This encoding thus makes sense for diagnostics, pretty printing, and constructing new attributes from a source-like specification.

isValid()

bool clang::ParamIdx::isValid ( ) const

inline

Is this parameter index valid?
