cadabra::Parser Class Reference

Description

Class which turns the string output of a preprocessor object and turns it into an Ex expression tree.

The output of preprocessor is assumed to be valid and consistent, so the code here is rather simple.

advance()

erase()

void Parser::erase

(

)

finalise()

void Parser::finalise

(

)

Finalise the parsed expression.

This function should be called when no further operator>> calls are going to be made, and is necessary to ensure that the tree is consistent.
