NAME

SYNOPSIS

    Text::Pipe::Multiplex->new;

DESCRIPTION

METHODS

"clear_pipes"

    $obj->clear_pipes;
    

Deletes all pipes that are attached to the multiplexer.

"count_pipes"

    my $count = $obj->count_pipes;
    

Counts the number of pipes attached to the multiplexer.

"deep_count"

Returns the total number of pipe segments that are attached to this segment, computed recursively. So if the multiplexer has three pipes attached, each of which consist of four pipes, this method will return 12.

"filter"

Takes input and sends it to each attached pipe. The results are returned in an array reference.

"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 attached pipes indicated by those indices. If only one index is given, the corresponding pipe 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 attached pipes array. 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"

Synonym for "clear_pipes()".

"pipes_count"

Synonym for "count_pipes()".

"pipes_index"

Synonym for "index_pipes()".

"pipes_pop"

    my $value = $obj->pipes_pop;
    

Pops the last attached pipe off the array, returning it.

"pipes_push"

    $obj->pipes_push(@values);
    

Pushes a pipe onto the end of the array of attached pipes.

"pipes_set"

    $obj->pipes_set(1 => $segment_1, 5 => $segment_2);
    

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

"pipes_shift"

    my $value = $obj->pipes_shift;
    

Shifts the first attached pipe off the array of attached pipes, 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 pipes designated by the offset and the length from the array, and replaces them with the pipe 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 pipes onto the beginning of the array of attached pipes.

"pop_pipes"

    my $value = $obj->pop_pipes;
    

Pops the last element off the array, returning it.

"push_pipes"

Synonym for "pipes_push()".

"set_pipes"

Synonym for "pipes_set()".

"shift_pipes"

Synonym for "pipes_shift()".

"splice_pipes"

Synonym for "pipes_splice()".

"unshift_pipes"

Synonym for "pipes_unshift()".
