Detailed Description

template<int bits>
class lcs::Expression< bits, BITBUFF_EXPR, void, void >

A class whose objects are created as temporary objects corresponding to an expression consisting of only an lcs::BitBuffer object. A user of libLCS will never need to use this class explicitly. Implicitly, this class is used everytime a continuous assignment is requested using the function lcs::Bus::cass.

Member Function Documentation

template<int bits>

void lcs::Expression< bits, BITBUFF_EXPR, void, void >::notify

(

Module *

mod

)

[inline]

This function can be used by a lcs::Module derivative to be notified of line state changes in the busses used in the expression.

template<int bits>

void lcs::Expression< bits, BITBUFF_EXPR, void, void >::operator=

(

const LineState &

l

)

Assignment operator for assignment from with a lcs::LineState value.

template<int bits>

void lcs::Expression< bits, BITBUFF_EXPR, void, void >::operator=

(

const Expression< bits, BITBUFF_EXPR, void, void > &

expr

)

Assignment operator for assignment with a similar expression.

template<int bits>

template<int w, ExprType Type, typename LExprType, typename RExprType>

void lcs::Expression< bits, BITBUFF_EXPR, void, void >::operator=

(

const Expression< w, Type, LExprType, RExprType > &

expr

)

Assignment operator for assignment with an expression.

template<int bits>

const LineState lcs::Expression< bits, BITBUFF_EXPR, void, void >::operator[]

(

int

index

)

const throw (OutOfRangeException<int>)

Returns the bit state (which is a result of the one's complement operation performed by the expression) at the index specified.

template<int bits>

int lcs::Expression< bits, BITBUFF_EXPR, void, void >::width

(

void

)

const [inline]

Returns the width for which an lcs::Expression object is valid.
