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.

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.

setID

public void setID(String id)

Overrides:

setID in class SimpleBNode

getID

public String getID()

Description copied from interface: BNode

Retrieves this blank node's identifier.

Specified by:

getID in interface BNode

Overrides:

getID in class SimpleBNode

Returns:

A blank node identifier.

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: BNode

Compares this blank node to another object.

Specified by:

equals in interface BNode

Overrides:

equals in class AbstractBNode

Parameters:

o - the object to compare this blank node to

Returns:

true, if the other object is an instance of BNode and their IDs are equal; false, otherwise.
