Name Binary::Heap::Array - Extensible array each of whose component arrays is an integral power of two wide. Synopsis my $a = Binary::Heap::Array::new(); $a->push(1)->push(2); ok $a->size == 2; ok $a->at( 0) == 1; ok $a->at( 1) == 2; ok $a->at(-1) == 2; ok $a->at(-2) == 1; $a->at(0) = 2; ok $a->at(-2) == 2; ok $a->pop == 2; ok $a->size == 1; Methods new() Create a new binary heap Array at :lvalue($array, $index) Address the element at a specified index so that it can get set or got Parameter Description 1 $array Array 2 $index index of element pop($array) Pop the topmost element from the leading full array and spread the remainder of its contents as sub arrays of the correct size for each preceding empty slot Parameter Description 1 $array Array from which an element is to be popped push($array, $element) Push a new element on to the top of the array by accumulating the leading full sub arrays in the first empty slot or create a new slot if none already available Parameter Description 1 $array Array 2 $element element to push size($array) Find the number of elements in the binary heap array Parameter Description 1 $array Array Index Alphabetic list of methods: "at :lvalue($array, $index)" "new()" "pop($array)" "push($array, $element)" "size($array)" Installation This module is written in 100% Pure Perl in a single file and is thus easy to read, modify and install. Standard Module::Build process for building and installing modules: perl Build.PL ./Build ./Build test ./Build install See also The arrays used to construct the binary heap array are all an integral power of two wide and thus make good use of the memory allocated by Data::Layout::BuddySystem or similar.
