HeaderValueFormatter

org.apache.http.message.HeaderValueFormatter
Known Indirect Subclasses

Class Overview

Interface for formatting elements of a header value. This is the complement to HeaderValueParser. Instances of this interface are expected to be stateless and thread-safe.

All formatting methods accept an optional buffer argument. If a buffer is passed in, the formatted element will be appended and the modified buffer is returned. If no buffer is passed in, a new buffer will be created and filled with the formatted element. In both cases, the caller is allowed to modify the returned buffer.

Summary

Public Methods
abstract CharArrayBuffer formatElements(CharArrayBuffer buffer, HeaderElement[] elems, boolean quote)
Formats an array of header elements.
abstract CharArrayBuffer formatHeaderElement(CharArrayBuffer buffer, HeaderElement elem, boolean quote)
Formats one header element.
abstract CharArrayBuffer formatNameValuePair(CharArrayBuffer buffer, NameValuePair nvp, boolean quote)
Formats one name-value pair, where the value is optional.
abstract CharArrayBuffer formatParameters(CharArrayBuffer buffer, NameValuePair[] nvps, boolean quote)
Formats the parameters of a header element.

Public Methods

public abstract CharArrayBuffer formatElements (CharArrayBuffer buffer, HeaderElement[] elems, boolean quote)

Formats an array of header elements.

Parameters
buffer the buffer to append to, or null to create a new buffer
elems the header elements to format
quote true to always format with quoted values, false to use quotes only when necessary
Returns
  • a buffer with the formatted header elements. If the buffer argument was not null, that buffer will be used and returned.

public abstract CharArrayBuffer formatHeaderElement (CharArrayBuffer buffer, HeaderElement elem, boolean quote)

Formats one header element.

Parameters
buffer the buffer to append to, or null to create a new buffer
elem the header element to format
quote true to always format with quoted values, false to use quotes only when necessary
Returns
  • a buffer with the formatted header element. If the buffer argument was not null, that buffer will be used and returned.

public abstract CharArrayBuffer formatNameValuePair (CharArrayBuffer buffer, NameValuePair nvp, boolean quote)

Formats one name-value pair, where the value is optional.

Parameters
buffer the buffer to append to, or null to create a new buffer
nvp the name-value pair to format
quote true to always format with a quoted value, false to use quotes only when necessary
Returns
  • a buffer with the formatted name-value pair. If the buffer argument was not null, that buffer will be used and returned.

public abstract CharArrayBuffer formatParameters (CharArrayBuffer buffer, NameValuePair[] nvps, boolean quote)

Formats the parameters of a header element. That's a list of name-value pairs, to be separated by semicolons. This method will not generate a leading semicolon.

Parameters
buffer the buffer to append to, or null to create a new buffer
nvps the parameters (name-value pairs) to format
quote true to always format with quoted values, false to use quotes only when necessary
Returns
  • a buffer with the formatted parameters. If the buffer argument was not null, that buffer will be used and returned.
