MutableHashTable -- the class of all mutable hash tables

The type MutableHashTable is a member of the class Type. Each object of class MutableHashTable is called a mutable hash table. Each mutable hash table is also a member of class HashTable.

More general types (whose methods may also apply) :

  • HashTable -- the class of all hash tables

    • Types of mutable hash table :

  • CacheTable -- hash tables for caching
  • ChainComplexMap -- the class of all maps between chain complexes
  • GradedModule -- the class of all graded modules
  • GradedModuleMap -- the class of all maps between graded modules
  • GroebnerBasis -- the class of all Groebner bases
  • ICnode
  • IndexedVariableTable -- the class of indexed variable tables
  • MonomialIdeal -- the class of all monomial ideals handled by the engine
  • MonomialOrdering
  • primdecComputation
  • Resolution -- the class of all resolution computations
  • ScriptedFunctor -- the class of all scripted functors
  • Type -- the class of all types
  • Variety -- the class of all algebraic varieties
  • Vector -- the class of all elements of free modules which are handled by the engine

    • A mutable hash table is a type of hash table whose entries can be changed.

    Normally the entries in a mutable hash table are not printed, to prevent infinite loops in the printing routines. To print them out, use peek.

    i1 : x = new MutableHashTable

    o1 = MutableHashTable{...}

    o1 : MutableHashTable
    i2 : scan(0 .. 30, i -> x#i = i^2)
    i3 : x # 20

    o3 = 400
    i4 : x #? 40

    o4 = false
