commit

void commit(Map<String,Set<ConceptId>> resourceCache,
            Map<String,Set<ConceptId>> castingCache)
     throws GraknValidationException

Commits the graph and adds concepts for post processing directly to the cache bypassing the REST API.

Parameters:

resourceCache - The cache of resource jobs to be executed

castingCache - The cache of the casting jobs to be executed

Throws:

GraknValidationException - when the graph does not conform to the object concept

commitNoLogs

void commitNoLogs()
           throws GraknValidationException

Commits to the graph without submitting any commit logs.

Throws:

GraknValidationException - when the graph does not conform to the object concept

fixDuplicateCastings

boolean fixDuplicateCastings(String index,
                             Set<ConceptId> castingVertexIds)

Merges the provided duplicate castings.

Parameters:

castingVertexIds - The vertex Ids of the duplicate castings

Returns:

if castings were merged and a commit is required.

fixDuplicateResources

boolean fixDuplicateResources(String index,
                              Set<ConceptId> resourceVertexIds)

Parameters:

resourceVertexIds - The resource vertex ids which need to be merged.

Returns:

True if a commit is required.

getConcept

value - The value of the concept

Returns:

A concept with the matching key and value

validVertex

boolean validVertex(org.apache.tinkerpop.gremlin.structure.Vertex vertex)

Parameters:

vertex - The vertex to be checked against the underlaying graph

Returns:

true if the vertex is still valid and has not been removed
