Member Function Documentation

virtual int TinyXPath::token_syntax_decoder::i_get_action_counter (   )  [pure virtual]

Implemented in TinyXPath::token_redef.

bool TinyXPath::token_syntax_decoder::o_recognize (  xpath_construct  xc_current, bool  o_final )  [protected]

Recognize one XPath construction This function throws exceptions every time there's a failure in a backtracking attempt. This should only happen when o_final is false, otherwise we have a syntax error Parameters: xc_current  XPath construction to recognize o_final  true if we need to go on, false if it's just a trial in the backtracking

virtual void TinyXPath::token_syntax_decoder::v_action (  xpath_construct  xc_rule, unsigned  u_sub, unsigned  u_variable = 0, const char *  cp_literal = "" )  [pure virtual]

Pure virtual : action taken when processing the rule. Implemented in TinyXPath::token_redef.

void TinyXPath::token_syntax_decoder::v_syntax_decode (   )

Decodes the syntax of an XPath expression. On entry, the lexical analysis has already produced a list of basic tokens. Throws : syntax_error, syntax_overflow
