cascadeEdgeProviderRemovals

GraphAlterationBuilder cascadeEdgeProviderRemovals(boolean cascadeEdgeProviderRemovals)

Specifies if the edge providers associated to a vertex provider (the vertex provider is either the source or destination provider for that edge provider) being removed should be automatically removed too or not. By default, edge providers are not automatically removed whenever an associated vertex is removed. In that setting, if the associated edge providers are not specifically removed, an exception will be thrown to indicate that issue.

Parameters:

cascadeEdgeProviderRemovals - whether or not to automatically remove associated edge providers of removed vertex providers

Returns:

the current alteration builder

removeEdgeProvider

GraphAlterationBuilder removeEdgeProvider(java.lang.String edgeProviderName)

Removes the edge provider that has the given name

Parameters:

edgeProviderName - the name of the provider to remove

Returns:

the current alteration builder

Throws:

java.io.IOException

removeVertexProvider

GraphAlterationBuilder removeVertexProvider(java.lang.String vertexProviderName)

Removes the vertex provider that has the given name. Also removes the associated edge providers if true was specified when calling cascadeEdgeProviderRemovals(boolean).

Parameters:

vertexProviderName - the name of the provider to remove

Returns:

the current alteration builder

Throws:

java.io.IOException
