package com.pervasive.datarush.graphs

Provides classes and interfaces for the construction of executable dataflow graphs. In Pervasive DataRush, dataflow graphs are simply collections of linked dataflow operators. Thus defining a graph is an iterative process of adding operators to a container. Once defined, an executable instance of the graph can be produced. Users manage and monitor the execution of the graph using these instances.

Class	Description
DROperatorException	Wrapper for errors occurring during the execution of a dataflow graph.
EngineConfig	A collection of engine configuration settings.
EngineConfig.Ports	Nested class containing settings specific to ports.
EngineConfig.RemoteMonitoring	Settings in this object determine settings for remote monitoring
EngineConfig.Sort	Settings in this object determine default tuning for the Sort operator.
EngineProperty<T>	Defined configuration properties for the DataRush engine.
GraphCancellationException	Thrown to indicate the cancellation of a running dataflow graph.
GraphCompilationListener	Provides notification whenever an operator is compiled.
GraphPath	A sequence of names typically used to identify elements within nested namespaces.
GraphPaths	Factory for generating paths which provides for a standard separator and an escaping mechanism.
GraphState	Describes the state of a LogicalGraphInstance.
InputPortInstance	A runtime instance of a LogicalPort.
LogicalGraph	Represents a logical graph which is intended to be executed.
LogicalGraphFactory	Public factory for creating initially empty logical graphs.
LogicalGraphInstance	The executable artifact of a logical graph.
LogicalGraphInstances	Miscellaneous utilities for working with LogicalGraphInstance.
LogicalGraphInstanceView	A read-only super-interface of LogicalGraphInstance
LogicalGraphWithConfig
LogicalStatistic	Statistic associated with a LogicalPort or a LogicalOperator.
LogicalStatistic.Builder	A builder for statistics.
LogicalStatistics	Miscellaneous utilities and constants associated with the LogicalStatistic class.
LogicalSubgraph	Extension of LogicalGraph used by IterativeOperator's.
LogicalSubgraphFactory	Interface for creating subgraphs.
OperatorInstance	A runtime instance of a LogicalOperator.
OperatorState	The execution state of an operator within a graph.
OutputPortInstance	A runtime instance of a LogicalPort.
PathParseException	Exception thrown when the serialization of a path cannot be parsed.
PortInstance	A runtime instance of a LogicalPort.
PropertyValued	Shared interface implemented by LogicalGraph and OpenComposite.
StatisticsRegistry	For advanced use only; operator authors should not need to access this class.
