Memory full cache¶
This example shows how to manipulate a MemoryFullCache
object.
from __future__ import division, unicode_literals
from numpy import array
from gemseo.api import configure_logger
from gemseo.caches.memory_full_cache import MemoryFullCache
configure_logger()
Out:
<RootLogger root (INFO)>
Import¶
First, we import the array and the MemoryError
classes.
Create¶
We can create an instance of the MemoryFullCache
class. We can then
print it, and we can see it is empty.
cache = MemoryFullCache()
print(cache)
Out:
Name: MemoryFullCache
Type: MemoryFullCache
Tolerance: 0.0
Input names: None
Output names: None
Length: 0
Cache¶
We can manually add data into the cache. However, it has to be noted that
most of the time a cache is attached to an MDODiscipline
. Then, the
cache feeding has not to be performed explicitly by the user.
data = {"x": array([1.0]), "y": array([2.0])}
cache.cache_outputs(data, ["x"], data, ["y"])
data = {"x": array([2.0]), "y": array([3.0])}
cache.cache_outputs(data, ["x"], data, ["y"])
print(cache)
Out:
Name: MemoryFullCache
Type: MemoryFullCache
Tolerance: 0.0
Input names: ['x']
Output names: ['y']
Length: 2
Get all data¶
Once the cache has been filled, the user can get the length of the cache. The user can also print all the data contained inside the cache.
print(cache.get_length())
print(cache.get_all_data())
Out:
2
{1: {'inputs': {'x': array([1.])}, 'outputs': {'y': array([2.])}, 'jacobian': None}, 2: {'inputs': {'x': array([2.])}, 'outputs': {'y': array([3.])}, 'jacobian': None}}
Get last cached data¶
The user can access the last entry (inputs or outputs) which have been entered in the cache.
print(cache.get_last_cached_inputs())
print(cache.get_last_cached_outputs())
Out:
{'x': array([2.])}
{'y': array([3.])}
Clear¶
The user can clear an cache of all its entries by using the
MemoryFullCache.clear()
method:
cache.clear()
print(cache)
Out:
Name: MemoryFullCache
Type: MemoryFullCache
Tolerance: 0.0
Input names: None
Output names: None
Length: 0
