temporian.has_leak #

has_leak(
    output: EventSetNodeCollection,
    input: Optional[EventSetNodeCollection] = None,
) -> bool

Tests if a node depends on a leak operator.

Tests if a EventSetNode or collection of nodes depends on the only operator that can introduce future leakage: EventSet.leak().

Single input output example

>>> a = tp.input_node([("f", tp.float32)])
>>> b = a.moving_sum(5)
>>> c = b.leak(6)
>>> d = c.prefix("my_prefix_")
>>> e = d.moving_sum(7)
>>> # The computation of "e" contains a leak.
>>> tp.has_leak(e)
True
>>> # The computation of "e" given "d" does not contain a leak.
>>> tp.has_leak(e, d)
False

Parameters:

Name	Type	Description	Default
`output`	`EventSetNodeCollection`	Nodes to compute. Supports Node, dict of Nodes and list of Nodes.	required
`input`	`Optional[EventSetNodeCollection]`	Optional input nodes. Supports Node, dict of Nodes and list of Nodes. If not specified, assumes for the input nodes to be the the raw data inputs e.g. `tp.input_node()` and `tp.event_set()`.	`None`

Returns:

Type	Description
`bool`	True if and only if the computation of `output` from `inputs` depends
`bool`	on a `EventSet.leak()` operator.
