Because of cultural differences, I'm not sure by "filter out" whether you
mean include or exclude
but when filtering any collection type, #select: #detect and #reject: are
you main go to messages.
If you inspect your dictionary and on the meta tab filter for
...*select*...
you'll find #associationsSelect:
which works like this...
d := Dictionary newFromPairs: #( 1 2 3 4 5 6 ).
d associationsSelect: [ :asn | (asn key = 1) and: (asn value = 2) ]
d inspect. ==> Dictionary [1 item] (1->2 )
I notice there is not a similar #associationsReject:
so if needed you could add your own considering...
d := Dictionary newFromPairs: #( 1 2 3 4 5 6 ).
d associations select: [ :asn | (asn key = 1) and: (asn value = 2) ]
d inspect. ==> Array [1 item] (1->2)
d := Dictionary newFromPairs: #( 1 2 3 4 5 6 ).
d associations reject: [ :asn | (asn key = 1) and: (asn value = 2) ]
d inspect. ==> Array [2 items] (5->6 3->4)
