Member Function Documentation

void skParser::addParseNode (  skParseNode *  pNode  )

Saves a parse node to the list of temporary nodes. If an error occurs these will be cleared up Exceptions: Symbian  - a leaving function

void skParser::appendError (  const Char *  msg  )

this adds a compile error message to the list of messages Exceptions: Symbian  - a leaving function

void skParser::appendError (  const skString &  msg  )

this adds a compile error message to the list of messages Exceptions: Symbian  - a leaving function

void skParser::Cleanup (  TAny *  s  )  [static]

Called via Symbian CleanupStack in the event of a leave. This calls the cleanupTempNodes method in the parser Remarks: only available in Symbian version

int skParser::lex (  void *  lvalp, void *  lloc )

This message returns the next token in the stream. Parameters: lvalp  pointer to the YYSTYPE (token structure) lloc  pointer to the YYLTYPE (token position structure) Exceptions: Symbian  - a leaving function

skParser::operator TCleanupItem (   )

Conversion operator to Symbian TCleanupItem. This is provided to allow this object to be pushed by value onto the Symbian Cleanup Stack Remarks: only available in Symbian version

skExprNode* skParser::parseExpression (   )

this method instructs the parser to begin parsing the string passed into the constructor The string is assumed to contain an expression, beginning with "=" Returns: If the parse is valid, then this will return the top of the parse tree, which the caller should delete Exceptions: Symbian  - a leaving function

skMethodDefNode* skParser::parseMethod (   )

this method instructs the parser to begin parsing the string passed into the constructor The string is assumed to contain a method definition Returns: If the parse is valid, then this will return the top of the parse tree, which the caller should delete Exceptions: Symbian  - a leaving function

void skParser::removeTempString (  skString *  str  )

removes a string from the temporary string list Parameters: str  the string to remove

void skParser::setTopNode (  skParseNode *  pNode  )

sets the current top-level parse node Parameters: pNode  the method definition or expression node
