org.waveprotocol.wave.model.operation.OperationException
An exception thrown to indicate an operation was invalid or ill-formed. An operation is well-formed if it satisfies some basic sanity checks, such as only positive arguments for retain, no two successive annotation boundaries, correct nesting of starts and ends, etc. Validity of an operation depends on the document that it is supposed to apply to. Validity checks include that the items specified in deletion or update components as well as annotations actually match the document, and that the operation preserves the XML schema. Code that deals with operations may assume that they are well-formed; ill-formed operations should be rejected at construction or deserialization time. It cannot always assume they are valid for a given context.
