ABSTRACT

FreeDB query response

DESCRIPTION

InfoSys::FreeDB::Response::Query contains information about FreeDB query responses.

CONSTRUCTOR

new(OPT_HASH_REF): Creates a new InfoSys::FreeDB::Response::Query object. OPT_HASH_REF is a hash reference used to pass initialization options. OPT_HASH_REF is mandatory. On error an exception Error::Simple is thrown.; Options for OPT_HASH_REF may include:
new_from_content_ref(CONTENT_REF): Creates a new InfoSys::FreeDB::Response::Query object from the specified content reference. CONTENT_REF is a string reference. On error an exception Error::Simple is thrown.

METHODS

exists_match(ARRAY): Returns the count of items in ARRAY that are in the match list.
get_code(): This method is inherited from package InfoSys::FreeDB::Response. Returns the response code.
get_match( [ INDEX_ARRAY ] ): Returns an ARRAY containing the match list. INDEX_ARRAY is an optional list of indexes which when specified causes only the indexed elements in the ordered list to be returned. If not specified, all elements are returned.
get_result(): This method is inherited from package InfoSys::FreeDB::Response. Returns the response result text.
is_error(): This method is inherited from package InfoSys::FreeDB::Response. Returns whether the response has an error or not.
is_exact_match(): Returns whether the query found an exact match or not.
pop_match(): Pop and return an element off the match list. On error an exception Error::Simple is thrown.
push_match(ARRAY): Push additional values on the match list. ARRAY is the list value. On error an exception Error::Simple is thrown.
set_code(VALUE): This method is inherited from package InfoSys::FreeDB::Response. Set the response code. VALUE is the value. On error an exception Error::Simple is thrown.
set_error(VALUE): This method is inherited from package InfoSys::FreeDB::Response. State that the response has an error. VALUE is the value. On error an exception Error::Simple is thrown.
set_exact_match(VALUE): State that the query found an exact match. VALUE is the value. On error an exception Error::Simple is thrown.
set_idx_match( INDEX, VALUE ): Set value in the match list. INDEX is the integer index which is greater than or equal to 0. VALUE is the value.
set_match(ARRAY): Set the match list absolutely. ARRAY is the list value. On error an exception Error::Simple is thrown.
set_num_match( NUMBER, VALUE ): Set value in the match list. NUMBER is the integer index which is greater than 0. VALUE is the value.
set_result(VALUE): This method is inherited from package InfoSys::FreeDB::Response. Set the response result text. VALUE is the value. On error an exception Error::Simple is thrown.
shift_match(): Shift and return an element off the match list. On error an exception Error::Simple is thrown.
unshift_match(ARRAY): Unshift additional values on the match list. ARRAY is the list value. On error an exception Error::Simple is thrown.
