Uses of DataflowVariable in groovyx.gpars.activeobject

Methods in groovyx.gpars.activeobject that return DataflowVariable

Uses of DataflowVariable in groovyx.gpars.dataflow

Subclasses of DataflowVariable in groovyx.gpars.dataflow

static class	DataflowVariable.RemoteDataflowVariable<T>
class	LazyDataflowVariable<T> Represents a thread-safe single-assignment, multi-read variable with delayed initialization.
class	SyncDataflowVariable<T> A synchronous variant of DataflowVariable, which blocks the writer as well as the readers.

Fields in groovyx.gpars.dataflow declared as DataflowVariable

private static DataflowVariable<java.lang.Object>

Dataflows.DUMMY

Fields in groovyx.gpars.dataflow with type parameters of type DataflowVariable

private java.util.concurrent.LinkedBlockingQueue<DataflowVariable<T>>	DataflowQueue.queue Stores the received DataflowVariables in the buffer.
private java.util.Queue<DataflowVariable<T>>	DataflowQueue.requests Stores unsatisfied requests for values
private java.util.concurrent.ConcurrentMap<java.lang.Object,DataflowVariable<java.lang.Object>>	Dataflows.variables

Methods in groovyx.gpars.dataflow that return DataflowVariable

private DataflowVariable<T>	DataflowQueue.copyDFV(java.util.Queue<DataflowVariable<T>> from, java.util.Queue<DataflowVariable<T>> to)
protected DataflowVariable<T>	DataflowQueue.createVariable() Creates a new variable to perform the next data exchange
protected DataflowVariable<T>	SyncDataflowQueue.createVariable() Creates a new variable to perform the next data exchange
private DataflowVariable<java.lang.Object>	Dataflows.ensureToContainVariable(java.lang.Object name) The idea is following: we try to putIfAbsent dummy DFV in to map if something real already there we are done if not we obtain lock and put new DFV with double check Unfortunately we have to sync on this as there is no better option (God forbid to sync on name)
private DataflowVariable<java.lang.Object>	Dataflows.putNewUnderLock(java.lang.Object name) Utility method extracted just to help JIT
DataflowVariable<java.lang.Object>	Dataflows.remove(java.lang.Object name) Removes a DFV from the map and binds it to null, if it has not been bound yet
private DataflowVariable<T>	DataflowQueue.retrieveForBind() Takes the first unsatisfied value request and binds a value on it.
private DataflowVariable<T>	DataflowQueue.retrieveOrCreateVariable() Checks whether there's a DFV waiting in the queue and retrieves it.
