Member Enumeration Documentation

Type

enum Rose::BinaryAnalysis::SymbolicExpressionParser::Token::Type

Token types.

Enumerator
NONE	End of input.
LTPAREN	Left parenthesis.
RTPAREN	Right parenthesis.
BITVECTOR	Numeric constant.
SYMBOL	Symbol. Symbols are basically anything but white space, comments, and the other token types.

Constructor & Destructor Documentation

Token() [1/3]

Rose::BinaryAnalysis::SymbolicExpressionParser::Token::Token ( )

inline

Constructs an end-of-input token with no position information.

Definition at line 77 of file SymbolicExpressionParser.h.

Token() [2/3]

Rose::BinaryAnalysis::SymbolicExpressionParser::Token::Token ( Type  tokenType, const SymbolicExpression::Type &  exprType, const std::string &  lexeme, unsigned  lineNumber, unsigned  columnNumber  )

inline

Constructs a specific token from a string.

Do not use this to construct numeric tokens.

Definition at line 81 of file SymbolicExpressionParser.h.

Token() [3/3]

Rose::BinaryAnalysis::SymbolicExpressionParser::Token::Token ( const Sawyer::Container::BitVector &  bv, const SymbolicExpression::Type &  exprType, const std::string &  lexeme, unsigned  lineNumber, unsigned  columnNumber  )

inline

Construct a token for a numeric constant.

Member Function Documentation

syntaxError()

SymbolicExpressionParser::SyntaxError Rose::BinaryAnalysis::SymbolicExpressionParser::Token::syntaxError ( const std::string &  mesg, const std::string &  name = "input"  ) const

inline

Creates a syntax error from a token plus message.

Definition at line 97 of file SymbolicExpressionParser.h.

tokenType()

Type Rose::BinaryAnalysis::SymbolicExpressionParser::Token::tokenType ( ) const

inline

Token type.

lexeme()

const std::string & Rose::BinaryAnalysis::SymbolicExpressionParser::Token::lexeme ( ) const

inline

Lexeme from which token was parsed.

Definition at line 105 of file SymbolicExpressionParser.h.

exprType()

SymbolicExpression::Type Rose::BinaryAnalysis::SymbolicExpressionParser::Token::exprType ( ) const

inline
