Class SubspaceProviderByKeySpacePath

java.lang.Object

com.apple.foundationdb.record.provider.foundationdb.SubspaceProviderByKeySpacePath

All Implemented Interfaces:

SubspaceProvider

@API(value=INTERNAL)
public class SubspaceProviderByKeySpacePath
extends Object
implements SubspaceProvider

A SubspaceProvider wrapping a key space path. Getting the subspace from this provider might be blocking if it is never retrieved before.

Method Summary

Modifier and Type	Method and Description
boolean	equals(Object other)
Subspace	getSubspace(FDBRecordContext context) This might be blocking if the subspace is never fetched before.
CompletableFuture<Subspace>	getSubspaceAsync(FDBRecordContext context) Asynchronously resolves the subspace against the database associated with FDBRecordContext.
int	hashCode()
LogMessageKeys	logKey()
String	toString()
String	toString(FDBRecordContext context) This method is typically called in support of error logging; hence, implementations should not assume a working FDBRecordContext but might, for example, use it to retrieve a subspace previously resolved against the corresponding database.

Method Detail

getSubspace

@Nonnull
public Subspace getSubspace(@Nonnull
                                     FDBRecordContext context)

Description copied from interface: SubspaceProvider

This might be blocking if the subspace is never fetched before.

Specified by:

getSubspace in interface SubspaceProvider

Parameters:

context - record context used to resolve the subspace

Returns:

Subspace

getSubspaceAsync

@Nonnull
public CompletableFuture<Subspace> getSubspaceAsync(@Nonnull
                                                             FDBRecordContext context)

Description copied from interface: SubspaceProvider

Asynchronously resolves the subspace against the database associated with FDBRecordContext.

Specified by:

getSubspaceAsync in interface SubspaceProvider

Parameters:

context - record context used to resolve the subspace

Returns:

CompletableFuture<Subspace>

logKey

@Nonnull

toString

public String toString(@Nonnull
                       FDBRecordContext context)

Description copied from interface: SubspaceProvider

This method is typically called in support of error logging; hence, implementations should not assume a working FDBRecordContext but might, for example, use it to retrieve a subspace previously resolved against the corresponding database.
