Public Methods

public void addHeader (String name, String value)

Adds a header to this message. The header will be appended to the end of the list.

Parameters
name the name of the header.
value the value of the header.

public void addHeader (Header header)

Adds a header to this message. The header will be appended to the end of the list.

Parameters
header the header to append.

public boolean containsHeader (String name)

Checks if a certain header is present in this message. Header values are ignored.

Parameters
name the header name to check for.
Returns
  • true if at least one header with this name is present.

public Header[] getAllHeaders ()

Returns all the headers of this message. Headers are orderd in the sequence they will be sent over a connection.

Returns
  • all the headers of this message

public Header getFirstHeader (String name)

Returns the first header with a specified name of this message. Header values are ignored. If there is more than one matching header in the message the first element of getHeaders(String) is returned. If there is no matching header in the message null is returned.

Parameters
name the name of the header to return.
Returns
  • the first header whose name property equals name or null if no such header could be found.

public Header[] getHeaders (String name)

Returns all the headers with a specified name of this message. Header values are ignored. Headers are orderd in the sequence they will be sent over a connection.

Parameters
name the name of the headers to return.
Returns
  • the headers whose name property equals name.

public Header getLastHeader (String name)

Returns the last header with a specified name of this message. Header values are ignored. If there is more than one matching header in the message the last element of getHeaders(String) is returned. If there is no matching header in the message null is returned.

Parameters
name the name of the header to return.
Returns
  • the last header whose name property equals name. or null if no such header could be found.

public HttpParams getParams ()

Returns the parameters effective for this message as set by setParams(HttpParams).

public HeaderIterator headerIterator (String name)

Returns an iterator of the headers with a given name.

Parameters
name the name of the headers over which to iterate, or null for all headers
Returns
  • Iterator that returns Header objects with the argument name in the sequence they are sent over a connection.

public HeaderIterator headerIterator ()

Returns an iterator of all the headers.

Returns
  • Iterator that returns Header objects in the sequence they are sent over a connection.

public void removeHeader (Header header)

Removes a header from this message.

Parameters
header the header to remove.

public void removeHeaders (String name)

Removes all headers with a certain name from this message.
