## org.optaplanner.core.impl.heuristic.selector.value.decorator
Class InitializedValueSelector

    java.lang.Object
      org.optaplanner.core.impl.heuristic.selector.AbstractSelector
          org.optaplanner.core.impl.heuristic.selector.value.AbstractValueSelector
              org.optaplanner.core.impl.heuristic.selector.value.decorator.InitializedValueSelector

All Implemented Interfaces:
  EventListener, Selector, ValueSelector, SolverPhaseLifecycleListener, SolverLifecycleListener

    public class InitializedValueSelector

extends AbstractValueSelector

Filters out every value that is planning entity for which the planning variable (for which this `ValueSelector` applies to) and that is uninitialized too.

Mainly used for chained planning variables.

Field Summary
`protected boolean` | `bailOutEnabled`
`protected ValueSelector` | `childValueSelector`
`protected PlanningVariableDescriptor` | `variableDescriptor`

Fields inherited from class org.optaplanner.core.impl.heuristic.selector.AbstractSelector
`logger, solverPhaseLifecycleSupport, workingRandom`

Constructor Summary
`InitializedValueSelector(ValueSelector childValueSelector)`

Method Summary
`protected long` | `determineBailOutSize(Object entity)`
`long` | `getSize(Object entity)` Similar to `IterableSelector.getSize()`, but requires an entity.
`PlanningVariableDescriptor` | `getVariableDescriptor()`
`boolean` | `isContinuous()` If true, then `Selector.isNeverEnding()` is also true.
`boolean` | `isNeverEnding()` Is true if `Selector.isContinuous()` is true or if this selector is in random order (for most cases).
`Iterator<Object>` | `iterator(Object entity)` Similar to `Iterable.iterator()`, but requires an entity.
`String` | `toString()`

Field Detail

### variableDescriptor

    protected final PlanningVariableDescriptor variableDescriptor

### childValueSelector

    protected final ValueSelector childValueSelector

### bailOutEnabled

    protected final boolean bailOutEnabled

Constructor Detail

### InitializedValueSelector

    public InitializedValueSelector(ValueSelector childValueSelector)

Method Detail

### getVariableDescriptor

    public PlanningVariableDescriptor getVariableDescriptor()

  Returns:
    never null

### isContinuous

    public boolean isContinuous()

  Description copied from interface: `Selector`
  If true, then `Selector.isNeverEnding()` is also true.

  Returns:
    true if any of the value ranges are continuous (as in for example every double value between 1.2 and 1.4)

### isNeverEnding

    public boolean isNeverEnding()

  Description copied from interface: `Selector`
  Is true if `Selector.isContinuous()` is true or if this selector is in random order (for most cases). Is never true when this selector is in shuffled order (which is less scalable but more exact).

  Returns:
    true if the `Iterator.hasNext()` of the `Iterator` created by `Iterable.iterator()` never returns false.

### getSize

    public long getSize(Object entity)

  Description copied from interface: `ValueSelector`
  Similar to `IterableSelector.getSize()`, but requires an entity.

  Parameters:
    `entity` - never null
  Returns:
    the approximate number of elements generated by this `Selector`, always >= 0

### iterator

    public Iterator<Object> iterator(Object entity)

  Description copied from interface: `ValueSelector`
  Similar to `Iterable.iterator()`, but requires an entity.

  Parameters:
    `entity` - never null
  Returns:
    never null

### determineBailOutSize

    protected long determineBailOutSize(Object entity)

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`
