Detailed Description

APC-backed and APCu-backed function memoization.

This class provides memoization for pure functions. A function is pure if its result value depends on nothing other than its input parameters and if invoking it does not cause any side-effects.

The first invocation of the memoized callable with a particular set of arguments will be delegated to the underlying callable. Repeat invocations with the same input parameters will be served from APC or APCu.

Example:

$memoizedStrrev = new MemoizedCallable( 'range' );
$memoizedStrrev->invoke( 5, 8 );  // result: array( 5, 6, 7, 8 )
$memoizedStrrev->invokeArgs( array( 5, 8 ) );  // same
MemoizedCallable::call( 'range', array( 5, 8 ) );  // same
