Method Detail

getProperty

public <A> A getProperty(String key)

Description copied from interface: TitanElement

Retrieves the value associated with the given key on this vertex and casts it to the specified type. If the key has cardinality SINGLE, then there can be at most one value and this value is returned (or null). Otherwise a list of all associated values is returned, or an empty list if non exist.

Specified by:

getProperty in interface TitanElement

Specified by:

getProperty in interface com.tinkerpop.blueprints.Element

Overrides:

getProperty in class AbstractVertex

Parameters:

key - string identifying a key

Returns:

value or list of values associated with key

getProperty

public <A> A getProperty(PropertyKey key)

Description copied from interface: TitanElement

Retrieves the value associated with the given key on this vertex and casts it to the specified type. If the key has cardinality SINGLE, then there can be at most one value and this value is returned (or null). Otherwise a list of all associated values is returned, or an empty list if non exist.

Specified by:

getProperty in interface TitanElement

Overrides:

getProperty in class AbstractVertex

Parameters:

key - key

Returns:

value or list of values associated with key

addToQueryCache

protected void addToQueryCache(SliceQuery query,
                   EntryList entries)

Overrides:

addToQueryCache in class CacheVertex

query

public VertexCentricQueryBuilder query()

Description copied from interface: TitanVertex

Starts a new TitanVertexQuery for this vertex.

Initializes and returns a new TitanVertexQuery based on this vertex.

Specified by:

query in interface TitanVertex

Specified by:

query in interface InternalVertex

Specified by:

query in interface com.tinkerpop.blueprints.Vertex

Overrides:

query in class AbstractVertex

Returns:

New TitanQuery for this vertex

See Also:

TitanVertexQuery

getVertexLabel

public VertexLabel getVertexLabel()

Special handling to provide access to the label even though its a different vertex by accessing it directly in the enclosing transaction which will cache all vertex labels

Specified by:

getVertexLabel in interface TitanVertex

Overrides:

getVertexLabel in class AbstractVertex

Returns:

getAddedRelations

public List<InternalRelation> getAddedRelations(com.google.common.base.Predicate<InternalRelation> query)

Description copied from interface: InternalVertex

Returns an iterable over all newly added relations incident on this vertex that match the given predicate

Specified by:

getAddedRelations in interface InternalVertex

Overrides:

getAddedRelations in class StandardVertex

Returns:

hasLoadedRelations

public boolean hasLoadedRelations(SliceQuery query)

Description copied from interface: InternalVertex

Returns true if the results for the given query have already been loaded for this vertex and are locally cached.

Specified by:

hasLoadedRelations in interface InternalVertex

Overrides:

hasLoadedRelations in class CacheVertex

Returns:

hasRemovedRelations

public boolean hasRemovedRelations()

Description copied from interface: InternalVertex

Whether this vertex has removed relations

Specified by:

hasRemovedRelations in interface InternalVertex

Overrides:

hasRemovedRelations in class StandardVertex

Returns:

hasAddedRelations

public boolean hasAddedRelations()

Description copied from interface: InternalVertex

Whether this vertex has added relations

Specified by:

hasAddedRelations in interface InternalVertex

Overrides:

hasAddedRelations in class StandardVertex

Returns:

getLifeCycle

public byte getLifeCycle()

Specified by:

getLifeCycle in interface InternalElement

Overrides:

getLifeCycle in class StandardVertex

Returns:

The lifecycle of this element

See Also:

ElementLifeCycle

removeRelation

public void removeRelation(InternalRelation e)

Description copied from interface: InternalVertex

Deleted relation e from the adjacency list of this vertex and updates the state of the vertex to reflect the modification. Note that this method tolerates the prior removal of the vertex and hence does not throw an exception if the relation could not actually be removed from the adjacency list. This behavior was chosen to allow relation deletion while iterating over the list of adjacent relations, in which case the relation deletion is taken care of by the iterator and only vertex status update needs to be executed.

Specified by:

removeRelation in interface InternalVertex

Overrides:

removeRelation in class StandardVertex

Parameters:

e - TitanRelation to be removed

addRelation

public boolean addRelation(InternalRelation e)

Description copied from interface: InternalVertex

Add a new relation to the vertex

Specified by:

addRelation in interface InternalVertex

Overrides:

addRelation in class StandardVertex

Returns:
