Interface HeaderValueFormatter

All Known Implementing Classes:
BasicHeaderValueFormatter

public interface HeaderValueFormatter

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.

Since:
4.0

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

Method Detail

formatElements

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.

formatHeaderElement

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.

formatParameters

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.

formatNameValuePair

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.
