Class DataStoreTypes.SerializedItemDescriptor

java.lang.Object

com.launchdarkly.sdk.server.subsystems.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.

Constructor Detail

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

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
