A set may contain at most one element for each key. Membership testing and

The variadic class interface accepts < code class = "computeroutput" > < span class = "number" > 0< / span > < / code >
to < code class = "computeroutput" > < span class = "identifier" > FUSION_MAX_SET_SIZE< / span > < / code > elements,
where < code class = "computeroutput" > < span class = "identifier" > FUSION_MAX_SET_SIZE< / span > < / code >
is a user definable predefined maximum that defaults to < code class = "computeroutput" > < span class = "number" > 10< / span > < / code > .
2007-11-06 12:13:52 +00:00
Example:

You may define the preprocessor constant < code class = "computeroutput" > < span class = "identifier" > FUSION_MAX_SET_SIZE< / span > < / code >
2007-11-06 12:13:52 +00:00
before including any Fusion header to change the default. Example:
