ReferenceType

Describes what the field reference contains. More types can be added over time. Implementations should handle unknown reference types as gracefully as possible.

Enums
PATH Reference contains a GFS path or a local path.
BLOB_REF Reference points to a blobstore object. This could be either a v1 blobRef or a v2 blobstore2Info. Clients should check blobstore2Info first, since v1 is being deprecated.
INLINE Data is included into this proto buffer
BIGSTORE_REF Reference points to a bigstore object
COSMO_BINARY_REFERENCE Indicates the data is stored in cosmoBinaryReference.
