Description
I purpose extending the MultiHashMap to create an object filter which will filter a given collection of objects by a given field value.
For example:
I have a collection of 5 objects of class X. X has an int field i as shown below:
x1 i = 1
x2 i = 2
x3 i = 2
x4 i = 5
x5 i = 5
The extended MultiHashMap will filter those objects by the field i and store each sorted object into the map using the value of the field, i, as the key, such that the resulting MultiHashMap looks as follows:
key | values
1 | x1
2 | x2, x3
5 | x4, x5
I have a class which does this and I find it invaluable in my day to day work. I don't Collections has a similar one.
Kind regards,
John.
