ShortBlob (Google App Engine API for Java)

com.google.appengine.api.datastore

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.
