Method Detail

values

public static HttpVersion[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (HttpVersion c : HttpVersion.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static HttpVersion valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

lookAheadGet

public static HttpVersion lookAheadGet(byte[] bytes,
                                       int position,
                                       int limit)

Optimised lookup to find an Http Version and whitespace in a byte array.

Parameters:

bytes - Array containing ISO-8859-1 characters

position - The first valid index

limit - The first non valid index

Returns:

An HttpMethod if a match or null if no easy match.

lookAheadGet

public static HttpVersion lookAheadGet(ByteBuffer buffer)

Optimised lookup to find an HTTP Version and trailing white space in a byte array.

Parameters:

buffer - buffer containing ISO-8859-1 characters

Returns:

An HttpVersion if a match or null if no easy match.

toBytes

public byte[] toBytes()

toBuffer

public ByteBuffer toBuffer()

getVersion

public int getVersion()

is

public boolean is(String s)

asString

public String asString()

toString

public String toString()

Overrides:

toString in class Enum<HttpVersion>

fromString

public static HttpVersion fromString(String version)

Case insensitive fromString() conversion

Parameters:

version - the String to convert to enum constant

Returns:

the enum constant or null if version unknown

fromVersion

public static HttpVersion fromVersion(int version)
