EO::Array - array type collection
use EO::Array; $array = EO::Array->new(); $array->at( 0, 'bar' ); my $thing = $array->at( 0 ); $thing->delete( 0 ); $array->push('value'); my $value = $array->shift( $array->unshift( $array->pop() ) ); my $count = $array->count; my @array = @$array;
EO::Array is an OO wrapper around Perl's array type. It will act both as an object and as an array reference.
EO::Array inherits from EO::Collection.
EO::Array provides the following constructors beyond those that the parent class provides:
- new_with_array( ARRAYREF )
Prepares a EO::Array object that has all the elements contained in ARRAYREF.
- do( CODE )
The do method calls CODE with each of the elements of your array. It sets both $_ and the first argument passed to CODE as the element. The return value of CODE is added to a new array that is returned by the do method.
- select( CODE )
The select method calls CODE with each of the elements of your array, it works in a similar way to the do method. The only difference is that if CODE returns a true value, then the element is added to a new array which is returned from the select method.
- at( KEY [, VALUE] )
Gets and sets key value pairs. KEY should always be an integer. If provided VALUE will be placed in the EO::Array object at the index KEY.
- delete( KEY )
Deletes a key/value pair, indexed by key, from the EO::Array object.
Returns an integer representing the number of key/value pairs in the EO::Array object.
Returns a Perl array.
Removes an item from the end of the EO::Array and returns it
- push( LIST )
Adds items on to the end of the EO::Array object
Removes an item from the beginning of the EO::Array
- unshift( LIST )
Adds items on to the beginning of the EO::Array object
- splice( [OFFSET [, LENGTH [, LIST]]] )
Splice an array (see perldoc -f splice for more information).
Returns a new EO::Array object with the elements of the array reversed.
