                @Nullable
                java.lang.String description,
                @Nullable
                java.lang.Integer version,
                CompoundProcessor compoundProcessor)

Method Detail

execute

public void execute(IngestDocument ingestDocument)
             throws java.lang.Exception

Modifies the data of a document to be indexed based on the processor this pipeline holds

Throws:

java.lang.Exception

getId

public java.lang.String getId()

The unique id of this pipeline

getDescription

@Nullable
public java.lang.String getDescription()

An optional description of what this pipeline is doing to the data gets processed by this pipeline.

getVersion

@Nullable
public java.lang.Integer getVersion()

An optional version stored with the pipeline so that it can be used to determine if the pipeline should be updated / replaced.

Returns:

null if not supplied.

getCompoundProcessor

public CompoundProcessor getCompoundProcessor()

Get the underlying CompoundProcessor containing the Pipeline's processors

getProcessors

public java.util.List<Processor> getProcessors()

Unmodifiable list containing each processor that operates on the data.

getOnFailureProcessors

public java.util.List<Processor> getOnFailureProcessors()

Unmodifiable list containing each on_failure processor that operates on the data in case of exception thrown in pipeline processors

flattenAllProcessors

public java.util.List<Processor> flattenAllProcessors()

Flattens the normal and on failure processors into a single list. The original order is lost. This can be useful for pipeline validation purposes.
