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 >
2007-02-15 23:11:24 +00:00
The variadic form accepts < code class = "computeroutput" > < span class = "number" > 0< / span > < / code >
to < code class = "computeroutput" > < span class = "identifier" > FUSION_MAX_VECTOR_SIZE< / span > < / code >
elements, where < code class = "computeroutput" > < span class = "identifier" > FUSION_MAX_VECTOR_SIZE< / span > < / code >
is a user definable predefined maximum that defaults to < code class = "computeroutput" > < span class = "number" > 10< / span > < / code > .
2006-08-22 15:57:13 +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 >
2007-02-15 23:11:24 +00:00
You may define the preprocessor constant < code class = "computeroutput" > < span class = "identifier" > FUSION_MAX_VECTOR_SIZE< / span > < / code >
2006-08-22 15:57:13 +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 >
