Method Detail

custom

public static CustomOutputStrategy custom()

Creates a CustomOutputStrategy. Custom output strategies let pipeline developers decide which events are produced by the corresponding pipeline element.

Returns:

CustomOutputStrategy

custom

public static CustomOutputStrategy custom(boolean outputBoth)

Creates a CustomOutputStrategy.

Parameters:

outputBoth - If two input streams are expected by a pipeline element, you can use outputBoth to indicate whether the properties of both input streams should be available to the pipeline developer for selection.

Returns:

CustomOutputStrategy

append

public static AppendOutputStrategy append(EventProperty... appendProperties)

Creates a AppendOutputStrategy. Append output strategies add additional properties to an input event stream.

Parameters:

appendProperties - An arbitrary number of event properties that are appended to any input stream.

Returns:

AppendOutputStrategy

append

public static AppendOutputStrategy append(List<EventProperty> appendProperties)

fixed

public static FixedOutputStrategy fixed(EventProperty... fixedProperties)

Creates a FixedOutputStrategy. Fixed output strategies always output the schema defined by the pipeline element itself.

Parameters:

fixedProperties - An arbitrary number of event properties that form the output event schema

Returns:

FixedOutputStrategy

fixed

public static FixedOutputStrategy fixed(List<EventProperty> appendProperties)

keep

public static KeepOutputStrategy keep()

Creates a KeepOutputStrategy. Keep output strategies do not change the schema of an input event, i.e., the output schema matches the input schema.

Returns:

KeepOutputStrategy

keep

public static KeepOutputStrategy keep(boolean mergeInputStreams)

list

public static ListOutputStrategy list(String propertyRuntimeName)

transform

public static TransformOutputStrategy transform(TransformOperation... transformOperations)

customTransformation

public static CustomTransformOutputStrategy customTransformation()
