cf.Query.evaluate

Query.evaluate(x)

Evaluate the query operation for a given left hand side operand.

Note that for the query object q and any object, x, x==q is equivalent to q.evaluate(x) and x!=q is equivalent to q.evaluate(x)==False.

Parameters:

x:

The object for the left hand side operand of the query.

Returns:

out:

The result of the query. The nature of the result is dependent on the object type of x.

Examples:

>>> q = cf.Query('lt', 5.5)
>>> q.evaluate(6)
False

>>> q = cf.Query('wi', (1,2))
>>> array = numpy.arange(4)
>>> array
array([0, 1, 2, 3])
>>> q.evaluate(array)
array([False,  True,  True, False], dtype=bool)
