NAME

       JSON::Schema::Modern::Document - One JSON Schema document

VERSION

       version 0.582

SYNOPSIS

           use JSON::Schema::Modern::Document;

           my $document = JSON::Schema::Modern::Document->new(
             canonical_uri => 'https://example.com/v1/schema',
             metaschema_uri => 'https://example.com/my/custom/metaschema',
             schema => $schema,
           );
           my $foo_definition = $document->get('/$defs/foo');
           my %resource_index = $document->resource_index;

           my sanity_check = $document->validate;

DESCRIPTION

       This class represents one JSON Schema document, to be used by JSON::Schema::Modern.

ATTRIBUTES

   schema
       The actual raw data representing the schema.

   canonical_uri
       When passed in during construction, this represents the initial URI by which the document should be
       known. It is overwritten with the root schema's $id property when one exists, and as such can be
       considered the canonical URI for the document as a whole.

   metaschema_uri
       Sets the metaschema that is used to describe the document (or more specifically, any JSON Schemas
       contained within the document), which determines the specification version and vocabularies used during
       evaluation. Does not override any $schema keyword actually present in the schema document.

   evaluator
       A JSON::Schema::Modern object. Optional, unless custom metaschemas are used.

   resource_index
       An index of URIs to subschemas (JSON pointer to reach the location, and the canonical URI of that
       location) for all identifiable subschemas found in the document. An entry for URI '' is added only when
       no other suitable identifier can be found for the root schema.

       This attribute should only be used by JSON::Schema::Modern and not intended for use externally (you
       should use the public accessors in JSON::Schema::Modern instead).

       When called as a method, returns the flattened list of tuples (path, uri). You can also use
       "resource_pairs" which returns a list of tuples as arrayrefs.

   canonical_uri_index
       An index of JSON pointers (from the document root) to canonical URIs. This is the inversion of
       "resource_index" and is constructed as that is built up.

   errors
       A list of JSON::Schema::Modern::Error objects that resulted when the schema document was originally
       parsed. (If a syntax error occurred, usually there will be just one error, as parse errors halt the
       parsing process.) Documents with errors cannot be evaluated.

METHODS

   path_to_canonical_uri
       Given a JSON pointer (a path) within this document, returns the canonical URI corresponding to that
       location.  Only fragmentless URIs can be looked up in this manner, so it is only suitable for finding the
       canonical URI corresponding to a subschema known to have an $id keyword.

   contains
       Check if "schema" contains a value that can be identified with the given JSON Pointer.  See "contains" in
       Mojo::JSON::Pointer.

   get
       Extract value from "schema" identified by the given JSON Pointer.  See "get" in Mojo::JSON::Pointer.

   validate
       Evaluates the document against its metaschema. See "evaluate" in JSON::Schema::Modern.  For regular JSON
       Schemas this is redundant with creating the document in the first place (which also includes a validation
       check), but for some subclasses of this class, additional things might be checked that are not caught by
       document creation.

   TO_JSON
       Returns a data structure suitable for serialization. See "schema".
