NAME¶
Lire::DerivedSchema - Defines a schema for which the records are derived from
another schema
SYNOPSIS¶
my $schema = Lire::DlfSchema::load_schema( 'www-user_session' );
my $fields = $schema->fields();
DESCRIPTION¶
A Lire::DerivedSchema defines a schema for which the records are computed by an
analyser using the records of a base schema. An example of a derived schema is
the www-user_session schema which computes session information from the
records in the www schema.
base()¶
Returns the Lire::DlfSchema object from which this schema's records are derived.
can_join_schema( $schema )¶
Returns true if $schema can be joined with this schema. For a DerivedSchema,
this will be true only when $schema is an ExtendedSchema of this schema or
this schema's base. It is also possible to join the DerivedSchema with its
base.
