Constructor Details

HttpVersion

public HttpVersion(String text,
 boolean keepAliveDefault)

Creates a new HTTP version with the specified version string. You will not need to create a new instance unless you are implementing a protocol derived from HTTP, such as RTSP and ICAP.

Parameters:

keepAliveDefault - true if and only if the connection is kept alive unless the "Connection" header is set to "close" explicitly.

HttpVersion

HttpVersion(String text,
 boolean strict,
 boolean keepAliveDefault)

HttpVersion

public HttpVersion(String protocolName,
 int majorVersion,
 int minorVersion,
 boolean keepAliveDefault)

Creates a new HTTP version with the specified protocol name and version numbers. You will not need to create a new instance unless you are implementing a protocol derived from HTTP, such as RTSP and ICAP

Parameters:

keepAliveDefault - true if and only if the connection is kept alive unless the "Connection" header is set to "close" explicitly.

HttpVersion

private HttpVersion(String protocolName,
 int majorVersion,
 int minorVersion,
 boolean keepAliveDefault,
 boolean bytes)

Method Details

valueOf

public static HttpVersion valueOf(String text)

Returns an existing or new HttpVersion instance which matches to the specified protocol version string. If the specified text is equal to "HTTP/1.0", HTTP_1_0 will be returned. If the specified text is equal to "HTTP/1.1", HTTP_1_1 will be returned. Otherwise, a new HttpVersion instance will be returned.

valueOf

 boolean strict)

version0

private static HttpVersion version0(String text)

hasControlOrWhitespace

private static boolean hasControlOrWhitespace(String s,
 int end)

parseInt

protocolName

public String protocolName()

Returns the name of the protocol such as "HTTP" in "HTTP/1.0".

majorVersion

public int majorVersion()

Returns the name of the protocol such as 1 in "HTTP/1.0".

text

public String text()

Returns the full protocol version text such as "HTTP/1.0".

isKeepAliveDefault

public boolean isKeepAliveDefault()

Returns true if and only if the connection is kept alive unless the "Connection" header is set to "close" explicitly.
