Package b implements a B+tree.

Package proto is a generated protocol buffer package.

IsInvalidAction returns whether an error is a DeltaError with the Err field equal to ErrInvalidAction.

IsQuadExist returns whether an error is a DeltaError with the Err field equal to ErrQuadExists.

IsQuadNotExist returns whether an error is a DeltaError with the Err field equal to ErrQuadNotExist.

NewHasA construct a new HasA iterator, given the quad subiterator, and the quad direction for which it stands.

NewLinksTo construct a new LinksTo iterator around a direction and a subiterator of nodes.

NewQuadStoreReader creates a quad reader for a given QuadStore.

NewRemover creates a quad writer for a given QuadStore which removes quads instead of adding them.

NewResultReader creates a quad reader for a given QuadStore and iterator.

NewTransaction initialize a new transaction.

NewTransactionN initialize a new transaction with a predefined capacity.

NewTxWriter creates a writer that applies a given procedures for all quads in stream.

NewWriter creates a quad writer for a given QuadStore.

Unwrap returns an original QuadStore value if it was wrapped by Handle.

The different types of actions a transaction can do.

The different types of actions a transaction can do.

IgnoreDuplicates specifies whether duplicate quads cause an error during loading or are ignored.

IgnoreMissing specifies whether missing quads cause an error during deletion or are ignored.

DeltaError records an error and the delta that caused it.

A HasA consists of a reference back to the graph.QuadStore that it references, a primary subiterator, a direction in which the quads for that subiterator point, and a temporary holder for the iterator generated on Contains().

A LinksTo has a reference back to the graph.QuadStore (to create the iterators for each node) the subiterator, and the direction the iterator comes from.

Stats of a graph.

Transaction stores a bunch of Deltas to apply together in an atomic step on the database.

Ref defines an opaque "quad store reference" type.
