FunctionFilters are used in the functions library to specify which data you want to set or get. For example you can use filters to get a subset of a function. FunctionFilters can be quite complex and usually there is an alternative syntax to get the same result easier.
VariableValueFilter
For example if we have a grid f with 2 int arguments and one string component like this:
x\y |
0 |
1 |
2 |
|---|---|---|---|
0 |
a |
b |
c |
1 |
d |
e |
f |
2 |
g |
h |
i |
We can define a filtered function of this like this
f2 = f.Filter(new VariableValueFilter<int>(x,new[]{1,2}),new VariableValueFilter<int>(y,new[]{1,2}))
f2 look like this
x2\y2 |
1 |
2 |
|---|---|---|
1 |
e |
f |
2 |
h |
i |
