Member Function Documentation

void statement_writeln::traversal

(

)

[virtual]

The traversal method may be used to traverse each of the statements in the list.

Implements statement.

bool statement_writeln::execution_flows_out

(

)

const [virtual]

The execution_flows_out method may be used to determine whether the flow of execution, having entered this statement, can ever flow out again.

Returns:

true if exection flows out, false if it does not.

Note:

Where the answer is indeterminate, true is returned.

Implements statement.

bool statement_writeln::has_args

(

)

const [inline, protected]

The has_args method is used to determine whether or not this call has arguemnts.

Definition at line 58 of file writeln.h.

References elp, and expression_list::empty().

virtual void statement_writeln::pre_order_traversal

(

)

[protected, virtual]

The pre_order_traversal method is called before any of the expressions are traversed. The default implementation does nothing.

Reimplemented in statement_writeln_compile, and statement_writeln_pretty.

virtual void statement_writeln::infix_order_traversal	(	const expression::pointer &	ep,
		bool	last
	)			[protected, virtual]

The infix_order_traversal method is called after traversing each of the expressions. The default implementation does nothing.

Parameters:

	ep	The expression just traversed.
	last	true if this is the last expression in the list

Reimplemented in statement_writeln_compile, and statement_writeln_pretty.

virtual void statement_writeln::post_order_traversal

(

)

[protected, virtual]

The post_order_traversal method is called after all of the expressions have been traversed. The default implementation does nothing.

Reimplemented in statement_writeln_compile, and statement_writeln_pretty.

statement_writeln& statement_writeln::operator=

(

const statement_writeln &

)

[private]

The assignment operator. Do not use.
