public class FactorStoreRandom
extends FactorStore

a place to store factors during computation. This is a naive implementation. A better implementation would do better indexing.

Inner Class Summary
`private class` | `FactorStoreRandom.FacItr`

Field Summary
`private int` | `factorMaxSize`
`private Variable` | `last`
`private int` | `numFactors`
`private int` | `numVariables`
`private Factor[]` | `theFactors`
`private Variable[]` | `theVariables`

Constructor Summary
`FactorStoreRandom(Variable[] toSumOut, Factor[] initialFactors, int numInitFactors)` generate a factor store containing the given initial factors and initial variables.

Method Summary
`void` | `addFactor(Factor newFactor)`
`FactorIterator` | `emunFactorsRemaining()` Returns an iterator over the the remaining factors.
`FactorIterator` | `emunFactorsRemoved()` Returns an iterator over the factors that contain the variable var.
`boolean` | `hasNext()`
`Variable` | `next()`

Field Detail

### theFactors

    private Factor[] theFactors

### numFactors

    private int numFactors

### theVariables

    private Variable[] theVariables

### numVariables

    private int numVariables

### factorMaxSize

    private int factorMaxSize

### last

    private Variable last

Constructor Detail

### FactorStoreRandom

    public FactorStoreRandom(Variable[] toSumOut,
                             Factor[] initialFactors,
                             int numInitFactors)

  generate a factor store containing the given initial factors and initial variables.

Method Detail

### hasNext

    public boolean hasNext()

  Overrides:
    `hasNext` in class `FactorStore`

### next

    public Variable next()

  Overrides:
    `next` in class `FactorStore`

### addFactor

    public void addFactor(Factor newFactor)

  Overrides:
    `addFactor` in class `FactorStore`

### emunFactorsRemoved

    public FactorIterator emunFactorsRemoved()

  Returns an iterator over the factors that contain the variable var. Note that we remove the factors as we access them. We should really index properly so that this can be done in time proportional to the number of factors that contain the variable, not linear in the total number of factors.
  Overrides:
    `emunFactorsRemoved` in class `FactorStore`

### emunFactorsRemaining

    public FactorIterator emunFactorsRemaining()

  Returns an iterator over the the remaining factors.
  Overrides:
    `emunFactorsRemaining` in class `FactorStore`
