/** \def BOOST_VMD_IS_MULTI(sequence) |
|
|
|
\brief Determines if the sequence has more than one element, referred to as a multi-element sequence. |
|
|
|
sequence = a sequence |
|
|
|
returns = 1 if the sequence is a multi-element sequence, else returns 0. |
|
|
|
If the size of a sequence is known it is faster comparing that size to be greater |
|
than one to find out if the sequence is multi-element. But if the size of the |
|
sequence is not known it is faster calling this macro than getting the size and |
|
doing the previously mentioned comparison in order to determine if the sequence |
|
is multi-element or not. |
