Package net.sf.farrago.fennel

Defines the native interface used for accessing Fennel storage from Java.

Description

Interface Summary

FennelCmdExecutor	FennelCmdExecutor defines a mechanism for extending and modifying the command set understood by Fennel.
FennelDbHandle	FennelDbHandle is a public wrapper for FennelStorage, and represents a handle to a loaded Fennel database.
FennelJavaErrorTarget	FennelJavaErrorTarget represents a class of java objects that can handle row errors arising from Fennel streams.
FennelJavaStreamMap	FennelJavaStreamMap is needed when a Fennel TupleStream's definition includes calls to JavaTupleStreams.

Class Summary

FennelCmdExecutorImpl	FennelCmdExecutorImpl provides a default implementation for FennelCmdExecutor by calling FennelStorage.executeJavaCmd(net.sf.farrago.fem.fennel.FemCmd, long).
FennelDbHandleImpl	FennelDbHandle is a public wrapper for FennelStorage, and represents a handle to a loaded Fennel database.
FennelDynamicParamId	FennelDynamicParamId is an opaque type for the 32-bit integers used to uniquely identify dynamic parameters within a FennelStreamGraph.
FennelExecutionHandle	FennelExecutionHandle provides a handle for passing execution state from Farrago to Fennel.
FennelJavaHandle	FennelJavaHandles are FarragoAllocations which ensure that handles returned by FennelStorage.newObjectHandle get closed under all circumstances.
FennelStorage	FennelStorage is the JNI interface for calling Fennel from Farrago.
FennelStreamGraph	FennelStreamGraphs are FarragoAllocations for FemStreamGraphHandles.
FennelStreamHandle	FennelStreamHandle is an opaque handle to an underlying node in a FennelStreamGraph.
FennelSvptHandle	FennelSvptHandle is an opaque handle to a Fennel savepoint.
FennelTxnContext	FennelTxnContext manages the state of at most one Fennel transaction.
FennelUtil	Static utility methods related to Fennel storage.

Enum Summary

FennelDynamicParamId.StreamType

Indicates whether a stream that accesses a dynamic parameter produces or consumes the dynamic parameter

Package net.sf.farrago.fennel Description

Defines the native interface used for accessing Fennel storage from Java.

FennelStorage contains the native method declarations, which are wrapped by FennelDbHandle. ProxyGen implements the code generator used by the build to produce C++ classes for binding to Fennel. See the design doc for more details.
