Description

Interface Summary

FarragoTransform	A piece of generated code must implement this interface if it is to be callable from a Fennel JavaTransformExecStream wrapper.
FennelTupleReader	FennelTupleReader defines an interface for unmarshalling tuples returned by Fennel.

Class Summary

FarragoGeneratedCodeExamples	Sandbox for experiments in code generation.
FarragoJavaUdxIterator	FarragoJavaUdxIterator provides runtime support for a call to a Java UDX.
FarragoRuntimeContext	FarragoRuntimeContext defines runtime support routines needed by generated code.
FarragoRuntimeContext.StreamOwner	Inner class for taking care of closing streams without deallocating them.
FarragoRuntimeJdbcUtil	Provides runtime support for implementing JDBC interfaces.
FarragoTransform.InputBinding	InputBinding binds a JavaTransformExecStream input's streamId to the ordinal assigned to that input by the stream graph.
FarragoTransformImpl	FarragoTransformImpl provides a base class for generated implementations of FarragoTransform.
FarragoTupleIterResultSet	FarragoTupleIterResultSet is a refinement of TupleIterResultSet which exposes Farrago datatype semantics.
FarragoUdrInvocationFrame	FarragoUdrInvocationFrame represents one entry on the routine invocation stack for a given thread.
FarragoUdrRuntime	FarragoUdrRuntime exposes a runtime support interface which can be used by implementations of Farrago user-defined routines.
FennelAbstractTupleIter	FennelAbstractTupleIter implements the TupleIter interface by unmarshalling Fennel tuples from a buffer.
FennelOnlyResultSet	FennelOnlyResultSet is a refinement of FarragoTupleIterResultSet, where the result set consists of Fennel tuples.
FennelOnlyResultSet.FennelColumnGetter	ColumnGetter that reads columns from a Fennel tuple
FennelOnlyTupleReader	FennelOnlyTupleReader implements the FennelTupleReader interface for reading tuples from a query plan that can be executed exclusively in Fennel.
FennelPipeIterator	FennelPipeIterator implements the RestartableIterator interface, receiving data from a producer as ByteBuffer objects, and unmarshalling them to a consumer.
FennelPipeTupleIter	FennelPipeTupleIter implements the TupleIter interface, receiving data from a producer as ByteBuffer objects, and unmarshalling them to a consumer.
FennelRowCount	Class for holding the number of rows returned by a DML statement.
FennelTransformTupleIter	FennelTransformTupleIter implements the TupleIter interfaces by reading tuples from a Fennel JavaTransformExecStream.
FennelTupleIter	FennelTupleIter implements the TupleIter interfaces by reading tuples from a Fennel ExecStream.
FennelTupleWriter	FennelTupleWriter defines an interface for marshalling tuples to be sent to Fennel.
NativeRuntimeContext	NativeRuntimeContext integrates Fennel with FarragoRuntimeContext.
