org.waveprotocol.wave.client.editor.content.ContentTextNode
Content text node Wrapper that tracks multiple implementation text nodelets. This is because we can't trust the browser not to unpredictably split our text nodelets, so we simply allow & expect it. TODO(danilatos): Thorough details of how this stuff works. For now, NodeManager has some more information. See {@link ContentDocument} for more... @author danilatos@google.com (Daniel Danilatos) @author lars@google.com (Lars Rasmussen)
