Method Detail

bytesToString

public static java.lang.String bytesToString(byte[] buf,
                                             int start,
                                             int len)

Provides optimised conversion from bytes to Strings for known HTTP methods. The bytes are assumed to be an ISO-8859-1 encoded representation of an HTTP method. The method is not validated as being a token, but only valid HTTP method names will be returned.

Doing it this way is ~10x faster than using MessageBytes.toStringType() saving ~40ns per request which is ~1% of the processing time for a minimal "Hello World" type servlet. For non-standard methods there is an additional overhead of ~2.5ns per request.

Pretty much every request ends up converting the method to a String so it is more efficient to do this straight away and always use Strings.

Parameters:

buf - The byte buffer containing the HTTP method to convert

start - The first byte of the HTTP method

len - The number of bytes to convert

Returns:

The HTTP method as a String or null if the method is not recognised.
