Interface SyntheticRecordFromStoredRecordPlan

All Superinterfaces:

PlanHashable

@API(value=INTERNAL)
public interface SyntheticRecordFromStoredRecordPlan
extends PlanHashable

A plan for deriving synthetic records from a given record. Like SyntheticRecordPlan, but with the additional execute-time parameter of a seed record. While the former is used to generate all records to rebuild an index, this plan is used to generate affected records for a changed record to update just for those changes.

Method Summary

Modifier and Type	Method and Description
default <M extends Message> RecordCursor<FDBSyntheticRecord>	execute(FDBRecordStore store, FDBStoredRecord<M> record) Execute this plan.
<M extends Message> RecordCursor<FDBSyntheticRecord>	execute(FDBRecordStore store, FDBStoredRecord<M> record, byte[] continuation, ExecuteProperties executeProperties) Execute this plan.
Set<String>	getStoredRecordTypes() Get the possible record types for the stored record to which this plan can be applied.
Set<String>	getSyntheticRecordTypes() Get the possible record types for the synthetic record generated by this plan.

Method Detail

getStoredRecordTypes

@Nonnull
Set<String> getStoredRecordTypes()

Get the possible record types for the stored record to which this plan can be applied. If given a record whose type is not in this set, the plan may return an empty cursor or throw an exception.

Returns:

the set of record type names

getSyntheticRecordTypes

@Nonnull
Set<String> getSyntheticRecordTypes()

Get the possible record types for the synthetic record generated by this plan.

Returns:

the set of record type names

execute

@Nonnull
<M extends Message> RecordCursor<FDBSyntheticRecord> execute(@Nonnull
                                                                      FDBRecordStore store,
                                                                      @Nonnull

                                                                      @Nullable

                                                                      @Nonnull

Execute this plan.

Type Parameters:

M - type of raw record

Parameters:

store - record store against which to execute

record - the stored record from which to derive synthetic records, such as by join queries

continuation - continuation from a previous execution of this same plan

executeProperties - limits on execution

Returns:

a cursor of synthetic records

execute

@Nonnull
default <M extends Message> RecordCursor<FDBSyntheticRecord> execute(@Nonnull
                                                                              FDBRecordStore store,
                                                                              @Nonnull

Execute this plan.

Type Parameters:

M - type of raw record

Parameters:

store - record store against which to execute

record - the stored record from which to derive synthetic records, such as by join queries

Returns:

a cursor of synthetic records
