Description

Symbol Table, based on index trees using a hash on the key. Keys are always Strings. Stored values can be any type.

Synopsis

Documentation

type SymTab v = IndTree [(String, v)] #

Symbol Table. Stored values are polymorphic, but the keys are always strings.

emptyST :: SymTab v #

insertST :: (String, v) -> SymTab v -> SymTab v #

deleteST :: String -> SymTab v -> SymTab v #

lookupST :: String -> SymTab v -> Maybe v #

definedST :: String -> SymTab v -> Bool #

flattenST :: SymTab v -> [v] #

data IndTree t #

Index Trees (storing indexes at nodes).
