Detailed Description

A parser for the Bond scripting language.

The Parser parses the contents of a TokenCollection generated from a Lexer that has scanned Bond source code. Its output is a parse tree of objects that derive from ParseNode. The concrete type of the root node is TranslationUnit. The parse tree can then be used as input to a SemanticAnalyzer and CodeGenerator. A single Parser can be used to parse several collections of Tokens.

When writing a tool that requires a compiler front end, the interactions between the front end components, namely a Lexer, a Parser and a SemanticAnalyzer, can be managed by a FrontEnd.

Constructor & Destructor Documentation

Parser() [1/2]

Bond::Parser::Parser ( Allocator & allocator, CompilerErrorBuffer & errorBuffer, ParseNodeStore & store )

inline

Constructs a Parser object.

Parameters

allocator	The memory allocator from which ParseNodes are allocated.
errorBuffer	Buffer where error messages are pushed when syntax errors are encountered.
store	Store of owning pointers to the ParseNodes created by this Parser. The ParseNodes are destroyed when the store is destroyed. They reference the Tokens from which they were parsed, so the TokenCollections must outlive the store.

Parser() [2/2]

Bond::Parser::Parser ( const Parser & other )

delete

Member Function Documentation

GetErrorBuffer()

const CompilerErrorBuffer & Bond::Parser::GetErrorBuffer ( ) const

inline

Returns the buffer where error messages are pushed.

GetParseNodeStore()

ParseNodeStore & Bond::Parser::GetParseNodeStore ( )

inline

Returns the store of owning pointers to the ParseNodes created by this Parser.

operator=()

Parser & Bond::Parser::operator= ( const Parser & other )

delete

Parse() [1/2]

TranslationUnit * Bond::Parser::Parse

(

TokenCollection &

collection

)

Parses a sequence of Tokens and generates a parse tree.

Parameters

Parse() [2/2]

(

TokenStream &

stream

)

Parses a sequence of Tokens and generates a parse tree.

Parameters

stream

The stream of Tokens to be parsed.

Returns

A parse tree of ParseNodes rooted with a TranslationUnit.
