getFactory

GremlinScriptEngineFactory getFactory()

Specified by:

getFactory in interface ScriptEngine

eval

default Traversal.Admin eval(Bytecode bytecode,
                             String traversalSource)
                      throws ScriptException

Evaluates Traversal Bytecode against a traversal source in the global bindings of the ScriptEngine.

Parameters:

bytecode - of the traversal to execute

traversalSource - to execute the bytecode against which should be in the available bindings.

Throws:

ScriptException

eval

Traversal.Admin eval(Bytecode bytecode,
                     Bindings bindings,
                     String traversalSource)
              throws ScriptException

Evaluates Traversal Bytecode with the specified Bindings. These Bindings supplied to this method will be merged with global engine bindings and override them where keys match.

Throws:

ScriptException
