LexicalHandler.new

def (self)

Creates a new handler.

LexicalHandler.onComment

def (self, token, offset)

The parser calls this method when it has parsed a line of comment. The token parameter is a string containing the characters that were read. The offset parameter is the position of the token in the script. If the comment is split into multiple lines, this method is called for each lines of the comment.

If this method returns false the parser stops and reports an error.

LexicalHandler.onCommentBegin

def (self, offset)

The parser calls this method when it has parsed the begin of a comment. The offset parameter is the position of the comment in the script.

If this method returns false the parser stops and reports an error.

LexicalHandler.onCommentEnd

def (self, offset)

The parser calls this method when it has parsed the end of a comment. The offset parameter is the position after the comment in the script.

If this method returns false the parser stops and reports an error.

LexicalHandler.onModulePathToken

def (self, context, token, offset)

The parser calls this method when it has parsed an element of a module path. The context is an array containing the previous elements of the module path as strings and the token parameter is the current element being parsed. The offset parameter is the position of the token in the script.

If this method returns false the parser stops and reports an error.

LexicalHandler.onNewLine

def (self, lineNumber, offset)

The parser calls this method when it is about to parse a new line. The lineNumber parameter is the number of the next line starting from 1. The offset parameter is the position of the new line in the script.

If this method returns false the parser stops and reports an error.

LexicalHandler.onScriptBegin

def (self)

The parser calls this method when it begin the parsing of the script. The parser calls this method just once, after the call to parse, and before any other method in this class are called.

If this method returns false the parser stops and reports an error.

LexicalHandler.onScriptEnd

def (self)

The parser calls this method when the parsing reach the end of the script. The parser calls this method just once and is the last handler function called.

If this method returns false the parser stops and reports an error.

LexicalHandler.onSymbolToken

def (self, context, token, offset)

The parser calls this method when it has parsed an user defined symbol. The context is an array containing the path to the symbol as strings (e.g. ['System', OS] for System.OS.getType) and the tokenparameter is the current symbol being parsed. The offset` parameter is the position of the token in the script.

If this method returns false the parser stops and reports an error. �

def (self, context, offset)

The parser calls this method when it was expecting an user defined symbol but found nothing. The context is an array containing the path to the expected symbol as strings (e.g. ['System', OS] for System.OS.). The offset` parameter is the position where the token was expected in the script.

If this method returns false the parser stops and reports an error. �

LexicalHandler.onToken

def (self, % type, token, offset)

The parser calls this method when it has parsed a token. The type parameter is a value of Token that provides the type of the token and the token parameter is the string representation of the token. The offset parameter is the position of the token in the script.

If this method returns false the parser stops and reports an error.

LexicalHandler.onWhiteSpace

def (self, token, offset)

The parser calls this method when it has parsed blank characters. The token parameter is a string containing the characters that were read. The offset parameter is the position of the token in the script.

If this method returns false the parser stops and reports an error.

LexicalHandler.parse

def (const self, stream)

Parses the script provided by stream. The stream parameter must implement the read part of the serializer interface and provide a getChar method. Returns true on success; otherwise returns false.
