Examples of com.google.wave.api.OperationQueue

com.google.wave.api.OperationQueue
A utility class that abstracts the queuing of operations, represented by {@link OperationRequest}, using easily callable functions. The {@link OperationQueue} queues the resulting operations in order.Typically there shouldn't be a need to call this directly unless operations are needed on entities outside of the scope of the robot. For example, to modify a blip that does not exist in the current context, you might specify the wave, wavelet, and blip id to generate an operation. Any calls to this will not be reflected in the robot in any way. For example, calling wavelet_append_blip will not result in a new blip being added to the robot current context, only an operation to be sent to the robot proxy.
