Method Details

setInternalID

public void setInternalID(long internalID,
 ValueStoreRevision revision)

Description copied from interface: LmdbValue

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

Specified by:

setInternalID in interface LmdbValue

getValueStoreRevision

public ValueStoreRevision getValueStoreRevision()

Description copied from interface: LmdbValue

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 LmdbValue

Returns:

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

setFromInitializedValue

public void setFromInitializedValue(LmdbValue initializedValue)

Description copied from interface: LmdbValue

Sets this value's data from an initialized value.

This must be only called within a synchronized block in the init() method of the uninitialized value.

Specified by:

setFromInitializedValue in interface LmdbValue

Parameters:

initializedValue - the initialized value to copy data from

getInternalID

public long getInternalID()

Description copied from interface: LmdbValue

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

Specified by:

getInternalID in interface LmdbValue

Returns:

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

getNamespace

public String getNamespace()

Description copied from interface: IRI

Gets the namespace part of this IRI.

The namespace is defined as per the algorithm described in the class documentation.

Specified by:

getNamespace in interface IRI

Returns:

the namespace of this IRI

getLocalName

public String getLocalName()

Description copied from interface: IRI

Gets the local name part of this IRI.

The local name is defined as per the algorithm described in the class documentation.

Specified by:

getLocalName in interface IRI

Returns:

the local name of this IRI

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

init

public void init()

Description copied from interface: LmdbValue

Initializes this value if it was a lazy value (ID-only value) before.

Specified by:

init in interface LmdbValue

equals

public boolean equals(Object o)

Description copied from interface: IRI

Compares this IRI to another object.

Specified by:

equals in interface IRI

Overrides:

equals in class Object

Parameters:

o - the object to compare this IRI to

Returns:

true, if the other object is an instance of IRI and their string values are equal; false, otherwise

hashCode

public int hashCode()

Description copied from interface: IRI

Computes the hash code of this IRI.

Specified by:

hashCode in interface IRI

Overrides:

hashCode in class Object

Returns:

a hash code for this IRI computed as Value.stringValue().hashCode()

writeReplace

protected Object writeReplace()
                       throws ObjectStreamException

Throws:

ObjectStreamException

toString

public String toString()

Overrides:

toString in class Object
