- All Implemented Interfaces:
- Cloneable, ContentLengthHeader, Header, Serializable, SIPHeaderNames
- public class ContentLength
- extends SIPHeader
- implements ContentLengthHeader
ContentLength SIPHeader (of which there can be only one in a SIPMessage).
Fielding, et al. Standards Track [Page 119]
RFC 2616 HTTP/1.1 June 1999
14.13 Content-Length
The Content-Length entity-header field indicates the size of the
entity-body, in decimal number of OCTETs, sent to the recipient or,
in the case of the HEAD method, the size of the entity-body that
would have been sent had the request been a GET.
Content-Length = "Content-Length" ":" 1*DIGIT
An example is
Content-Length: 3495
Applications SHOULD use this field to indicate the transfer-length of
the message-body, unless this is prohibited by the rules in section
4.4.
Any Content-Length greater than or equal to zero is a valid value.
Section 4.4 describes how to determine the length of a message-body
if a Content-Length is not given.
Note that the meaning of this field is significantly different from
the corresponding definition in MIME, where it is an optional field
used within the "message/external-body" content-type. In HTTP, it
SHOULD be sent whenever the message's length can be determined prior
to being transferred, unless this is prohibited by the rules in
section 4.4.

ContentLength
public ContentLength()
- Default constructor.
ContentLength
public ContentLength(int length)
- Constructor given a length.
getContentLength
public int getContentLength()
- get the ContentLength field.
- Specified by:
getContentLength
in interface ContentLengthHeader
- Returns:
- int
setContentLength
public void setContentLength(int contentLength)
throws InvalidArgumentException
- Set the contentLength member
- Specified by:
setContentLength
in interface ContentLengthHeader
- Parameters:
contentLength
- int to set
- Throws:
InvalidArgumentException
- if contentLength is less than zero.
encodeBody
public String encodeBody()
- Encode into a canonical string.
- Overrides:
encodeBody
in class SIPHeader
- Returns:
- String
match
public boolean match(Object other)
- Pattern matcher ignores content length.
- Overrides:
match
in class SIPObject
- Parameters:
other
- the match pattern to test against. The match object
has to be of the same type (class). Primitive types
and non-sip fields that are non null are matched for equality.
Null in any field matches anything. Some book-keeping fields
are ignored when making the comparison.
