isRestorable
public boolean isRestorable()- Specified by:
isRestorablein interfaceMetadata.MetadataCustom<Metadata.ProjectCustom>- Returns:
- true if this custom could be restored from snapshot
-
getWriteableName
Description copied from interface:VersionedNamedWriteableReturns the name of the writeable object- Specified by:

-
getMinimalSupportedVersion
Description copied from interface:VersionedNamedWriteableThe minimal version of the recipient this object can be sent to. SeeVersionedNamedWriteable.supportsVersion(TransportVersion)for the default serialization check.- Specified by:
getMinimalSupportedVersionin interfaceVersionedNamedWriteable
-
writeTo
Description copied from interface:WriteableWrite this into the StreamOutput.- Specified by:

fromXContent
- Throws:

toXContentChunked
Description copied from interface:ChunkedToXContentCreate an iterator ofToXContentchunks for a REST response. Each chunk is serialized with the sameXContentBuilderandToXContent.Params, which is also the same as theToXContent.Paramspassed as theparamsargument. For best results, all chunks should beO(1)size. The last chunk in the iterator must always yield at least one byte of output. See alsoChunkedToXContentHelperfor some handy utilities.Note that chunked response bodies cannot send deprecation warning headers once transmission has started, so implementations must check for deprecated feature use before returning.
- Specified by:

- iterator over chunks of
ToXContent
