=head1 NAME

Etcd3::Range

=cut

our $VERSION = '0.007';

=head1 DESCRIPTION

Range gets the keys in the range from the key-value store.

=head1 ACCESSORS

=head2 endpoint

=cut

has endpoint => (
    is      => 'ro',
    isa     => Str,
);

=head2 key

key is the first key for the range. If range_end is not given, the request only looks up key.
the key is encoded with base64.  type bytes

=cut

has key => (
    is       => 'ro',
    isa      => Str,
    required => 1,
    coerce   => sub { return encode_base64( $_[0], '' ) }
);

=head2 range_end

range_end is the upper bound on the requested range [key, range_end). If range_end is '\0',
the range is all keys >= key. If the range_end is one bit larger than the given key, then
the range requests get the all keys with the prefix (the given key). If both key and
range_end are '\0', then range requests returns all keys. the key is encoded with base64.
type bytes.  NOTE: If range_end is not given, the request only looks up key.

=cut

has range_end => (
    is     => 'ro',
    isa    => Str,
    coerce => sub { return encode_base64( $_[0], '' ) }
);

=head2 prev_key

If prev_kv is set, etcd gets the previous key-value pairs before deleting it. The previous key-value
pairs will be returned in the delete response.  This is only used for delete.

=cut

has prev_key => (
    is     => 'ro',
    isa    => Bool,
    coerce => sub { no strict 'refs'; return $_[0] ? JSON::true : JSON::false }
);


=head2 limit

limit is a limit on the number of keys returned for the request. type int64

=cut

has limit => (
    is  => 'ro',
    isa => Int,
);

=head2 revision

lib/Etcd3/KV/Range.pm  view on Meta::CPAN

=head2 min_mod_revision

min_mod_revision is the lower bound for returned key mod revisions;
all keys with lesser mod revisions will be filtered away.

=cut

has min_mod_revision => (
    is  => 'ro',
    isa => Int,
);

=head2 max_mod_revision

max_mod_revision is the upper bound for returned key mod revisions;
all keys with greater mod revisions will be filtered away.

=cut

has max_mod_revision => (
    is  => 'ro',
    isa => Int,
);

=head2 min_create_revision

min_create_revision is the lower bound for returned key create revisions;
all keys with lesser create revisions will be filtered away.

=cut

has min_create_revision => (
    is  => 'ro',
    isa => Int,
);

=head2 max_create_revision

max_create_revision is the upper bound for returned key create revisions;
all keys with greater create revisions will be filtered away.

=cut

has max_create_revision => (
    is  => 'ro',
    isa => Int,
);

=head2 delete

DeleteRange deletes the given range from the key-value store. A delete request increments the
revision of the key-value store and generates a delete event in the event history for every
deleted key.

    $etcd->range({key =>'test0'})->delete

=cut

sub delete {
    my ( $self ) = @_;
    $self->{endpoint} => '/kv/deleterange',
    return $self->request;
}
