Class Documentation

struct erpcgen::AstWalker::bottom_up

Specifier type to select bottom-up handler using ADL.

struct erpcgen::AstWalker::top_down

Specifier type to select top-down handler using ADL.

Constructor & Destructor Documentation

erpcgen::AstWalker::AstWalker ( const std::string &  inputFile )

inlineexplicit

Constructor.

This function initializes object attributes.

Parameters

[in]

inputFile

Parsed file name.

Member Function Documentation

template<typename D >

void AstWalker::dispatch ( AstNode *  node )

protected

This function invoke the appropriate handler method for the node's token type..

This function call handle functions for AstNode, which is specified with node token. The template argument D specifies whether the top-down or bottom-up handler should be called, by passing either of the top_down or bottom_up typenames.

Parameters

[in]

node

Node to handle.

Exceptions

internal_error

Thrown if handle function return new node, which want replace given node, but given node is root.

void AstWalker::walk(AstNode * node)

void AstWalker::startWalk ( AstNode *  node )

virtual

This function walk the AstNode depth-first and invoke handler methods.

Parameters

[in]

node

The root node of the tree to walk.

void AstWalker::dispatch(AstNode * node)

void AstWalker::walk(AstNode * node)

void AstWalker::walk ( AstNode *  node )

protectedvirtual

This function walk the AstNode depth-first and invoke handler methods.

This function call for dispatch given node before and after calling walk function for node children.

Parameters

[in]

node

The root node of the tree to walk.
