Class CorruptValue

java.lang.Object

org.eclipse.rdf4j.sail.nativerdf.model.CorruptValue

All Implemented Interfaces:

Serializable, Value, NativeValue

Direct Known Subclasses:

CorruptIRI, CorruptIRIOrBNode, CorruptLiteral, CorruptUnknownValue

public class CorruptValue
extends Object
implements NativeValue

CorruptValue is used when a NativeValue cannot be read from the ValueStore and if soft failure is enabled

  There is no method isCorruptValue() as it would exist for a "regular" implementation of NativeValue. Since CorruptValue is only to be used in exceptional situations, the recommended way of checking for it is using "instanceof".

CorruptValue

public CorruptValue(ValueStoreRevision revision,
 int internalID,
 byte[] data)

Method Details

setInternalID

public void setInternalID(int internalID,
 ValueStoreRevision revision)

Description copied from interface: NativeValue

Sets the ID that is used for this value in a specific revision of the value store.

Specified by:

setInternalID in interface NativeValue

getValueStoreRevision

public ValueStoreRevision getValueStoreRevision()

Description copied from interface: NativeValue

Gets the revision of the value store that created this value. The value's internal ID is only valid when it's value store revision is equal to the value store's current revision.

Specified by:

getValueStoreRevision in interface NativeValue

Returns:

The revision of the value store that created this value at the time it last set the value's internal ID.

getInternalID

public int getInternalID()

Description copied from interface: NativeValue

Gets the ID that is used in the native store for this Value.

Specified by:

getInternalID in interface NativeValue

Returns:

The value's ID, or NativeValue.UNKNOWN_ID if not yet set.

stringValue

public String stringValue()

Description copied from interface: Value

Returns the String-value of a Value object. This returns either a Literal's label, a IRI's URI or a BNode's ID.

Specified by:

stringValue in interface Value

getData

public byte[] getData()

Returns the bytes that were read from the ValueStore for this value's internalID. Since the value is corrupt the data may be null or an empty array.

Returns:

null, empty array or corrupt data

equals

public boolean equals(Object o)

Overrides:

equals in class Object
