Class DataStoreTypes.SerializedItemDescriptor

  • Enclosing class:
    DataStoreTypes
    public static final class DataStoreTypes.SerializedItemDescriptor
extends java.lang.Object
    A versioned item (or placeholder) storable in a PersistentDataStore.

    This is equivalent to DataStoreTypes.ItemDescriptor, but is used for persistent data stores. The SDK will convert each data item to and from its serialized string form; the persistent data store deals only with the serialized form.

      • SerializedItemDescriptor

        public SerializedItemDescriptor​(int version,
                                boolean deleted,
                                java.lang.String serializedItem)
        Constructs a new instance.
        Parameters:
        version - the version number
        deleted - true if this is a deleted item placeholder
        serializedItem - the serialized data (will not be null)

    • Method Detail

      • getVersion

        public int getVersion()
        Returns the version number of this data, provided by the SDK.
        Returns:
        the version number

      • isDeleted

        public boolean isDeleted()
        Returns true if this is a placeholder (tombstone) for a deleted item. If so, getSerializedItem() will still contain a string representing the deleted item, but the persistent store implementation has the option of not storing it if it can represent the placeholder in a more efficient way.
        Returns:
        true if this is a deleted item placeholder

      • getSerializedItem

        public java.lang.String getSerializedItem()
        Returns the data item's serialized representation. This will never be null; for a deleted item placeholder, it will contain a special value that can be stored if necessary (see isDeleted()).
        Returns:
        the serialized data or null
