Constructor Details

ErrorSink

public ErrorSink(ErrorConfiguration errorConfig)

Parameters:

errorConfig - controls whether error thrown at composition time or runtime

Method Details

getErrorConfig

public ErrorConfiguration getErrorConfig()

getInput

public RecordPort getInput()

Description copied from interface: RecordSinkOperator

Gets the record port providing the input data to the sink.

Specified by:

getInput in interface RecordSinkOperator

Specified by:

getInput in interface SinkOperator<RecordPort>

Returns:

the input port for the sink

computeMetadata

protected void computeMetadata(StreamingMetadataContext ctx)

Description copied from class: DeferredCompositeOperator

Implementations must adhere to all of the contracts specified by StreamingOperator.computeMetadata(com.pervasive.datarush.operators.StreamingMetadataContext). In addition, DeferredCompositeOperators must declare required metadata so as to satisfy requirements of the operators that are added during DeferredCompositeOperator.compose(com.pervasive.datarush.operators.DeferredCompositionContext).

Specified by:

computeMetadata in class DeferredCompositeOperator

Parameters:

ctx - the context

compose

protected void compose(DeferredCompositionContext ctx)

Description copied from class: DeferredCompositeOperator

Compose the body of this operator. Implementations should do the following:

1. Instantiate and configure sub-operators, adding them to the provided context via the method OperatorComposable.add(O)
2. Create necessary connections via the method OperatorComposable.connect(P, P). This includes connections from the composite's input ports to sub-operators, connections between sub-operators, and connections from sub-operators output ports to the composite's output ports

Specified by:

compose in class DeferredCompositeOperator

Parameters:

ctx - the context
