<title>Function object wrapper size</title>
|
||||
<para> Function object wrappers will be the size of a struct containing a member function pointer and two data pointers. The actual size can vary significantly depending on the underlying platform; on 32-bit Mac OS X with GCC, this amounts to 16 bytes, while it is 32 bytes Windows with Visual C++. Additionally, the function object target may be allocated on the heap, if it cannot be placed into the small-object buffer in the <code>boost::function</code> object.</para>
|
||||
<para> Function object wrappers will be the size of two function pointers plus one function pointer or data pointer (whichever is larger). On common 32-bit platforms, this amounts to 12 bytes per wrapper. Additionally, the function object target will be allocated on the heap.</para>

<title>Copying efficiency</title>
|
||||
<para> Copying function object wrappers may require allocating memory for a copy of the function object target. The default allocator may be replaced with a faster custom allocator or one may choose to allow the function object wrappers to only store function object targets by reference (using <computeroutput>ref</computeroutput>) if the cost of this cloning becomes prohibitive. Small function objects can be stored within the <code>boost::function</code> object itself, improving copying efficiency.</para>
