Class IceCandidateSdpEncoder

java.lang.Object
  org.lastbamboo.common.ice.sdp.IceCandidateSdpEncoder

All Implemented Interfaces:

IceCandidateVisitor<org.apache.commons.lang.ObjectUtils.Null>

public class IceCandidateSdpEncoder
extends Object
implements IceCandidateVisitor<org.apache.commons.lang.ObjectUtils.Null>

Class for encoding ICE candidates into SDP. For a discussion of the priorities associated with each candidate type and for a general discussion of ICE, this was written based on draft-ietf-mmusic-ice-16 at:

http://www.tools.ietf.org/html/draft-ietf-mmusic-ice-16

Here's the augmented BNF for candidates: candidate-attribute = "candidate" ":" foundation SP component-id SP transport SP priority SP connection-address SP ;from RFC 4566 port ;port from RFC 4566 SP cand-type [SP rel-addr] [SP rel-port] *(SP extension-att-name SP extension-att-value) foundation = 1*32ice-char component-id = 1*5DIGIT transport = "UDP" / transport-extension transport-extension = token ; from RFC 3261 priority = 1*10DIGIT cand-type = "typ" SP candidate-types candidate-types = "host" / "srflx" / "prflx" / "relay" / token rel-addr = "raddr" SP connection-address rel-port = "rport" SP port extension-att-name = byte-string ;from RFC 4566 extension-att-value = byte-string ice-char = ALPHA / DIGIT / "+" / "/"
