Member Function Documentation

void expression_logical_and_pretty::pre_order_traversal

(

int

pprec

)

[protected, virtual]

The pre_order_traversal method is used to perform actions required before the left hand expression is traversed.

Parameters:

pprec

The parent expression's precedence. Not much use to code generators, but essential for pretty printers to get the parentheses correct.

Reimplemented from expression_logical_and.

void expression_logical_and_pretty::infix_order_traversal

(

int

pprec

)

[protected, virtual]

The infix_order_traversal method is used to perform actions required after the left hand expression is traversed and before the right hand expression is traversed.

Parameters:

pprec

The parent expression's precedence.

Reimplemented from expression_logical_and.

void expression_logical_and_pretty::post_order_traversal

(

int

pprec

)

[protected, virtual]

The post_order_traversal method is used to perform actions required after the right hand expression is traversed.

Parameters:

pprec

The parent expression's precedence. Not much use to code generators, but essential for pretty printers to get the parentheses correct.

Reimplemented from expression_logical_and.

expression::pointer expression_logical_and_pretty::optimize

(

)

const [protected, virtual]

The optimize method may be used to evaluate constant expressions, or substitute more efficient expressions.

This is intended to be called by the translator:: expression_statement method, or similar, where the expression is in its final form, and will get no deeper. In other words, when all available information has been provided.

There is no default implementation, even though most optimize implementations return self(), because this gives the compiler no opportunity to remind the authors of new classes that they have forgotten something.

Returns:

If the expression tree is not constant, or it is already as reduced as it can get, it returns itself. Otherwise, it returns a new expression node.

Implements expression.

expression_logical_and_pretty& expression_logical_and_pretty::operator=

(

const expression_logical_and_pretty &

)

[private]

The assignment operator. Do not use.
