Method Detail

doAdd

protected final <S extends M,T extends com.google.protobuf.Message> B doAdd(java.lang.Class<S> messageClassOrInterface,
                                                                            java.lang.Class<T> enrichmentClass,
                                                                            EnrichmentFn<S,C,T> func)

Adds an enrichment function to the builder.

Implementation Note:

This method does the real job of adding functions to the builder. The binding of the generic parameters allows type-specific functions exposed in the public API to call this method.

remove

public <T extends com.google.protobuf.Message> B remove(java.lang.Class<M> eventClass,
                                                        java.lang.Class<T> enrichmentClass)

Removes the enrichment function for the passed event class.

If the function for this class was not added, the call has no effect.

build

public abstract Enricher build()

Creates a new Enricher.
