NAME

SHARYANTO::Data::Util - Data utilities

VERSION

version 0.57

SYNOPSIS

DESCRIPTION

FUNCTIONS

None are exported by default, but they are exportable.

clone_circular_refs(@args) -> any

For example, this data:

    $x = [1];
    $data = [$x, 2, $x];

contains circular references by referring to $x twice. After clone_circular_refs, data will become:

    $data = [$x, 2, [1]];

that is, the subsequent circular references will be deep-copied. This makes it safe to transport to JSON, for example.

Sometimes it doesn't work, for example:

    $data = [1];
    push @$data, $data;

Cloning will still create circular references.

This function modifies the data structure in-place, and return true for success and false upon failure.

Arguments ('*' denotes required arguments):

• data* => any

Return value:

has_circular_ref(@args) -> any

Does not deal with weak references.

Arguments ('*' denotes required arguments):

• data* => any

Return value:

SEE ALSO

SHARYANTO

Data::Structure::Util has the XS/C version of has_circular_ref which is 3 times or more faster than this module's implementation which is pure Perl). Use that instead if possible (in some cases, Data::Structure::Util fails to build and this module provides an alternative for that function).

This module is however much faster than Devel::Cycle.
