data Balance Source

A balance summarizes several entries. You do not create a Balance directly. Instead, use entryToBalance.

Instances

Eq Balance
Show Balance
Monoid Balance	Add two Balances together. Commodities are never removed from the balance, even if their balance is zero. Instead, they are left in the balance. Sometimes you want to know that a commodity was in the account but its balance is now zero.

unBalance :: Balance -> Map Commodity BottomLine Source

Returns a map where the keys are the commodities in the balance and the values are the balance for each commodity. If there is no balance at all, this map can be empty.
