METHODS

clear_pipes

$obj->clear_pipes;

Deletes all elements from the array.

count_pipes

my $count = $obj->count_pipes;

Returns the number of elements in the array.

index_pipes

my $element   = $obj->index_pipes(3);
my @elements  = $obj->index_pipes(@indices);
my $array_ref = $obj->index_pipes(@indices);

Takes a list of indices and returns the elements indicated by those indices. If only one index is given, the corresponding array element is returned. If several indices are given, the result is returned as an array in list context or as an array reference in scalar context.

pipes

my @values    = $obj->pipes;
my $array_ref = $obj->pipes;
$obj->pipes(@values);
$obj->pipes($array_ref);

Get or set the array values. If called without an arguments, it returns the array in list context, or a reference to the array in scalar context. If called with arguments, it expands array references found therein and sets the values.

pipes_clear

$obj->pipes_clear;

Deletes all elements from the array.

pipes_count

my $count = $obj->pipes_count;

Returns the number of elements in the array.

pipes_index

my $element   = $obj->pipes_index(3);
my @elements  = $obj->pipes_index(@indices);
my $array_ref = $obj->pipes_index(@indices);

pipes_pop

my $value = $obj->pipes_pop;

Pops the last element off the array, returning it.

pipes_push

$obj->pipes_push(@values);

Pushes elements onto the end of the array.

pipes_set

$obj->pipes_set(1 => $x, 5 => $y);

Takes a list of index/value pairs and for each pair it sets the array element at the indicated index to the indicated value. Returns the number of elements that have been set.

pipes_shift

my $value = $obj->pipes_shift;

Shifts the first element off the array, returning it.

pipes_splice

$obj->pipes_splice(2, 1, $x, $y);
$obj->pipes_splice(-1);
$obj->pipes_splice(0, -1);

Takes three arguments: An offset, a length and a list.

Removes the elements designated by the offset and the length from the array, and replaces them with the elements of the list, if any. In list context, returns the elements removed from the array. In scalar context, returns the last element removed, or undef if no elements are removed. The array grows or shrinks as necessary. If the offset is negative then it starts that far from the end of the array. If the length is omitted, removes everything from the offset onward. If the length is negative, removes the elements from the offset onward except for -length elements at the end of the array. If both the offset and the length are omitted, removes everything. If the offset is past the end of the array, it issues a warning, and splices at the end of the array.

pipes_unshift

$obj->pipes_unshift(@values);

Unshifts elements onto the beginning of the array.

pop_pipes

my $value = $obj->pop_pipes;

Pops the last element off the array, returning it.

push_pipes

$obj->push_pipes(@values);

Pushes elements onto the end of the array.

set_pipes

$obj->set_pipes(1 => $x, 5 => $y);

Takes a list of index/value pairs and for each pair it sets the array element at the indicated index to the indicated value. Returns the number of elements that have been set.

shift_pipes

my $value = $obj->shift_pipes;

Shifts the first element off the array, returning it.

splice_pipes

$obj->splice_pipes(2, 1, $x, $y);
$obj->splice_pipes(-1);
$obj->splice_pipes(0, -1);

Takes three arguments: An offset, a length and a list.

unshift_pipes

$obj->unshift_pipes(@values);

Unshifts elements onto the beginning of the array.
