Class BasicLineFormatterHC4

java.lang.Object
  org.apache.http.message.BasicLineFormatterHC4

All Implemented Interfaces:

org.apache.http.message.LineFormatter

@Immutable
public class BasicLineFormatterHC4
extends java.lang.Object
implements org.apache.http.message.LineFormatter

Interface for formatting elements of the HEAD section of an HTTP message. This is the complement to LineParser. There are individual methods for formatting a request line, a status line, or a header line. The formatting does not include the trailing line break sequence CR-LF. The formatted lines are returned in memory, the formatter does not depend on any specific IO mechanism. Instances of this interface are expected to be stateless and thread-safe.

Since:

4.0

Field Detail

DEFAULT

@Deprecated
public static final BasicLineFormatterHC4 DEFAULT

Deprecated. (4.3) use INSTANCE

A default instance of this class, for use as default or fallback. Note that BasicLineFormatter is not a singleton, there can be many instances of the class itself and of derived classes. The instance here provides non-customized, default behavior.

initBuffer

protected org.apache.http.util.CharArrayBuffer initBuffer(org.apache.http.util.CharArrayBuffer charBuffer)

Obtains a buffer for formatting.

Parameters:

charBuffer - a buffer already available, or null

Returns:

the cleared argument buffer if there is one, or a new empty buffer that can be used for formatting

formatProtocolVersion

public static java.lang.String formatProtocolVersion(org.apache.http.ProtocolVersion version,
