Interface GraphStrategy

All Known Implementing Classes:

ComputerDataStrategy, IdentityStrategy, IdStrategy, PartitionStrategy, ReadOnlyStrategy, SequenceStrategy, SubgraphStrategy

public interface GraphStrategy

Defines a collection of functions that plug-in to Gremlin Structure API methods to enhance or alter the functionality of the implementation. The methods defined in GraphStrategy follow a common pattern where each method represents some injection point for new logic in the Gremlin Structure API. A method always accepts a StrategyContext which contains the context of the call being made and will have a different StrategyContext.getCurrent() object depending on that context (e.g the Vertex.addEdge(String, com.tinkerpop.gremlin.structure.Vertex, Object...) method will send the instance of the Vertex that was the object of that method call).

A method will always return a UnaryOperator where the argument and return value to it is a function with the same signature as the calling method where the strategy logic is being injected. The argument passed in to this function will be a reference to the original calling function (from an implementation perspective, it might be best to think of this "calling function" as the original Gremlin Structure API method that performs the ultimate operation against the graph). In constructing the outgoing function to the UnaryOperator, it should of course match the signature of the original calling function and depending on the functionality, call the original function to trigger a call to the underlying implementation.

The most simplistic implementation of a strategy method is to simply return a UnaryOperator.identity() which happens to be the default implementation for all the methods. By returning the identity function, the incoming original function is simply returned back unchanged with no additional enhancements to the execution of it.
