Member Function Documentation

bool ClassAdParser::ParseClassAd (  const std::string &  buffer, ClassAd &  ad, bool  full = false )

Parse a ClassAd. Parameters: buffer  Buffer containing the string representation of the classad. ad  The classad to be populated full  If this parameter is true, the parse is considered to succeed only if the ClassAd was parsed successfully and no other tokens follow the ClassAd. Returns: true on success, false on failure

ClassAd* ClassAdParser::ParseClassAd (  const std::string &  buffer, bool  full = false )

Parse a ClassAd. Parameters: buffer  Buffer containing the string representation of the classad. full  If this parameter is true, the parse is considered to succeed only if the ClassAd was parsed successfully and no other tokens follow the ClassAd. Returns: pointer to the ClassAd object if successful, or NULL otherwise

ExprTree* ClassAdParser::ParseExpression (  const std::string &  buffer, bool  full = false )

Parse an expression. Parameters: buffer  Buffer containing the string representation of the expression. full  If this parameter is true, the parse is considered to succeed only if the expression was parsed successfully and no other tokens are left. Returns: pointer to the expression object if successful, or NULL otherwise

bool ClassAdParser::ParseExpression (  const std::string &  buffer, ExprTree *&  expr, bool  full = false )

Parse an expression. Parameters: expr  Reference to a ExprTree pointer, which will be pointed to the parsed expression. The previous value of the pointer will be destroyed. full  If this parameter is true, the parse is considered to succeed only if the expression was parsed successfully and no other tokens follow the expression. Returns: true if the parse succeeded, false otherwise.
