Constructor

Create an instance, the argument within [ ] is optional.

/*
 * NOTE: if hiredis module is not available, it falls back
 * to use pure JS parser, and returns an instance of Boris.
 */
Hiboris( [ Object opt ] ) : Hiboris | Boris
// or
new Hiboris( [ Object opt ] ) : Hiboris | Boris

Options

Default options are listed.

opt = {
    /*
     * For default the hiredis native parser is disabled.
    */
    hiredis : false

    /*
     * For default, the parser returns strings instead of buffers,
     * returning buffers will slowdown hiredis parsing of about ~60%. 
     */
    , return_buffers : false
}

Sample Usage

See examples.

Methods

Arguments within [ ] are optional.

/*
 * parse a chunk of data.
 */
Hiboris#parse( Buffer data ) : undefined

/*
 * reset parser state.
 */
Hiboris#reset() : undefined

Events

/*
 * Parser has found some data.
 * 
 * NOTE: The 'convert' function argument is a shortcut to Bolgia#reveal
 * utility, it scans an array and turns all Buffers into Strings or Numbers.
 *
 * NOTE: the boolean 'isError' signals a Redis error reply, not a runtime Error.
 */
'match' : function ( Boolean isError, Array result, Function convert ) : undefined
