The numbered form accepts the exact number of elements. Example:
< / p >
< pre class = "programlisting" >
< span class = "identifier" > vector3< / span > < span class = "special" > < < / span > < span class = "keyword" > int< / span > < span class = "special" > ,< / span > < span class = "keyword" > char< / span > < span class = "special" > ,< / span > < span class = "keyword" > double< / span > < span class = "special" > > < / span >
< / pre >
< p >
2008-07-08 02:43:21 +00:00
The variadic form accepts < tt class = "computeroutput" > < span class = "number" > 0< / span > < / tt > to
< tt class = "computeroutput" > < span class = "identifier" > FUSION_MAX_VECTOR_SIZE< / span > < / tt > elements,
where < tt class = "computeroutput" > < span class = "identifier" > FUSION_MAX_VECTOR_SIZE< / span > < / tt >
is a user definable predefined maximum that defaults to < tt class = "computeroutput" > < span class = "number" > 10< / span > < / tt > .
2007-11-25 18:38:02 +00:00
Example:
< / p >
< pre class = "programlisting" >
< span class = "identifier" > vector< / span > < span class = "special" > < < / span > < span class = "keyword" > int< / span > < span class = "special" > ,< / span > < span class = "keyword" > char< / span > < span class = "special" > ,< / span > < span class = "keyword" > double< / span > < span class = "special" > > < / span >
< / pre >
< p >
2008-07-08 02:43:21 +00:00
You may define the preprocessor constant < tt class = "computeroutput" > < span class = "identifier" > FUSION_MAX_VECTOR_SIZE< / span > < / tt >
2007-11-25 18:38:02 +00:00
before including any Fusion header to change the default. Example:
< / p >
< pre class = "programlisting" >
< span class = "preprocessor" > #define< / span > < span class = "identifier" > FUSION_MAX_VECTOR_SIZE< / span > < span class = "number" > 20< / span >
