Method Detail

add

public abstract void add(org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversal graphTraversal)

Add one traversal to this TraversalBatch instance (thread-safe).

Parameters:

graphTraversal - the mutation traversal to add to this TraversalBatch instance.

addAll

public abstract void addAll(Iterable<org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversal> newTraversals)

Add multiple traversals to this TraversalBatch instance (thread-safe).

Parameters:

newTraversals - the mutation traversals to add to this TraversalBatch instance.

size

public abstract int size()

Return the number of operations currently contained in the TraversalBatch.

Calling this regularly is not great for performance. Also, this number may not be accurate in heavily concurrent situations.

Returns:

the number of operations currently contained in the TraversalBatch.

asGraphStatement

public abstract GraphStatement asGraphStatement()

Convert the TraversalBatch into a GraphStatement to execute on a DseSession.

Returns:

an executable statement instance.
