Class ShortBlob

java.lang.Object
  com.google.appengine.api.datastore.ShortBlob

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ShortBlob>

public final class ShortBlob
extends java.lang.Object
implements java.io.Serializable, java.lang.Comparable<ShortBlob>

ShortBlob contains an array of bytes no longer than DataTypeUtils.MAX_SHORT_BLOB_PROPERTY_LENGTH. Unlike Blob, ShortBlobs are indexed by the datastore and can therefore be filtered and sorted on in queries. If your data is too large to fit in a ShortBlob use Blob instead.
