Description

Prerequisite

Synopsis

Global functions are needed to define the input of the flex scanner and to start the bison parser. The input is taken from a string.

Motivation

It is necessary to be able to give an image expression in ASCII. This can be used in glish.

int msScanGramParseCommand (const MeasurementSet *ms, const String& command)

Declare the bison parser (is implemented by bison command).

void MSScanGramerror (char*)

The yyerror function for the parser. It throws an exception with the current token.

const TableExprNode *msScanGramParseNode()

Give the table expression node.

Int& msScanGramPosition()

Give the current position in the string. This can be used when parse errors occur.

int msScanGramInput (char* buf, int max_size)

Declare the input routine for flex/bison.
