        Benchmark

Benchmark a method or simple bit of code using different Graph classes. If the test code is the same for each graph class, then you can set it during instantiation through the argument test_string. The argument test_string can also be a tuple of test code and setup code. The code is entered as a string valid for use with the timeit module.

Example: >>> b=Benchmark(['Graph','XGraph']) >>> b['Graph']=('G.add_nodes_from(nlist)','nlist=range(100)') >>> b.run()

Instance Methods

[hide private]

__init__(self, graph_classes, title='', test_string=None, runs=3, reps=1000)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature source code

__setitem__(self, graph_class, (test_str, setup_str))
Set a simple bit of code and setup string for the test.

source code

run(self)
Run the benchmark for each class and print results.

source code

Set a simple bit of code and setup string for the test. Use this for cases where the code differs from one class to another.
