Detailed Description

A simple array of ports, indexed from 1..length.

class portArray takes care of dynamic memory allocation and deallocation, provides copy and assignment functions, and handles indexing errors.

A nice future improvement might be to overload the [] operator.

Member Function Documentation

port portArray::get ( int index ) const

Get a port from the array. Parameters: index   the index of the element to be returned Returns: the port Definition at line 102 of file port.cc. Referenced by circuit::build_tree(), and connection::get_port().

int portArray::len ( )

Returns: array length Definition at line 83 of file port.cc. Referenced by portStack::push().

portArray & portArray::operator= ( const portArray & a )

We must overload the = operator because we use dynamic memory. Definition at line 113 of file port.cc.

void portArray::set ( int index, port value )

Set an array element. Parameters: index   the index of the element to be set value   the new value Definition at line 88 of file port.cc. Referenced by circuit::connect(), connection::connection(), and zero().

void portArray::zero ( )

Set all array values to zero. Definition at line 96 of file port.cc.
