Method Summary

Modifier and Type	Method and Description
boolean	supportsComputer() Determines if the Graph implementation supports GraphComputer based processing.
boolean	supportsConcurrentAccess() Determines if the Graph implementation supports more than one connection to the same instance at the same time.
boolean	supportsThreadedTransactions() Determines if the Graph implementation supports threaded transactions which allow a transaction to be executed across multiple threads via Transaction.createThreadedTx().

Method Detail

supportsConcurrentAccess

public boolean supportsConcurrentAccess()

Description copied from interface: Graph.Features.GraphFeatures

Determines if the Graph implementation supports more than one connection to the same instance at the same time. For example, Neo4j embedded does not support this feature because concurrent access to the same database files by multiple instances is not possible. However, Neo4j HA could support this feature as each new Graph instance coordinates with the Neo4j cluster allowing multiple instances to operate on the same database.

supportsConcurrentAccess in interface Graph.Features.GraphFeatures

supportsComputer

public boolean supportsComputer()

Description copied from interface: Graph.Features.GraphFeatures

Determines if the Graph implementation supports GraphComputer based processing.

Specified by:

supportsThreadedTransactions

public boolean supportsThreadedTransactions()

Description copied from interface: Graph.Features.GraphFeatures

Determines if the Graph implementation supports threaded transactions which allow a transaction to be executed across multiple threads via Transaction.createThreadedTx().
