NAME
ZMQ::Declare::ZDCF::Validator - ZDCF validator
SYNOPSIS
use ZMQ::Declare;
my $validator = ZMQ::Declare::ZDCF::Validator->new;
unless ($validator->validate($datastructure)) {
die "Input data structure is not ZDCF!"
}DESCRIPTION
Validates that a given nested Perl data structure (arrays, hashes, scalars) is actually a valid ZDCF tree.
METHODS
validate
Returns true if the given Perl data structure is a valid ZDCF tree, false otherwise.
Dies if the specification version of the ZDCF tree is unsupported.
The second parameter to this method can optionally be a major ZDCF specification version to use for validation instead of auto-detection.
validate_and_upgrade
Validates the input ZDCF structure, then attempts to upgrade it to the newest supported spec version. Returns a cloned copy of the input structure on success or undef on failure.
upgrade_structure
Given a ZDCF structure, determines the specification version and tries to upgrade it to the most recent supported version.
Does not validate the input and works in-place.
find_spec_version
Returns the version of the provided specification.
Returns undef on failure.
