Static Public Member Functions | |
static bool | isSipPort (uint16_t port) |
Represents a general SIP message. It's an abstract class and cannot be instantiated. It's inherited by SipRequestLayer and SipResponseLayer
|
virtual |
Set the content-length only if a content-length field already exists and if its current value is different than the total length of the next layer(s)
Reimplemented from pcpp::TextBasedProtocolMessage.
int pcpp::SipLayer::getContentLength | ( | ) | const |
The length of the body of many SIP response messages is determined by a SIP header field called "Content-Length". This method parses this field, extracts its value and return it. If this field doesn't exist 0 is returned
|
inlinevirtual |
Implements pcpp::Layer.
|
inlinestatic |
A static method that checks whether the port is considered as SIP
[in] | port | The port number to be checked |
|
virtual |
Currently identifies only SDP if content-length field exists and set to a value greater than zero. If content-length field doesn't exist or set to zero and still there is data after this layer, a PayloadLayer will be created
Reimplemented from pcpp::TextBasedProtocolMessage.
HeaderField* pcpp::SipLayer::setContentLength | ( | int | contentLength, |
const std::string | prevFieldName = "" |
||
) |
The length of the body of many SIP messages is determined by a header field called "Content-Length". This method sets The content-length field value. The method supports several cases:
[in] | contentLength | The content length value to set |
[in] | prevFieldName | Optional parameter, if specified and "Content-Length" field doesn't exist, it will be created after this field |
