Method Detail
-
getSize
public long getSize()
Description copied from interface:CountableValueRangeUsed by uniform random selection in a composite or nullable CountableValueRange.- Returns:
- the exact number of elements generated by this
CountableValueRange, always>= 0
-
get
public BigDecimal get(long index)
Description copied from interface:CountableValueRangeUsed by uniform random selection in a composite or nullable CountableValueRange.- Parameters:
index- always<CountableValueRange.getSize()- Returns:
- sometimes null (if
PlanningVariable.nullable()is true)
-
contains
public boolean contains(BigDecimal value)
- Parameters:
value- sometimes null- Returns:
- true if the ValueRange contains that value
-
createOriginalIterator
public Iterator<BigDecimal> createOriginalIterator()
Description copied from interface:CountableValueRangeSelect the elements in original (natural) order.- Returns:
- never null
-
createRandomIterator
public Iterator<BigDecimal> createRandomIterator(Random workingRandom)
Description copied from interface:ValueRangeSelect in random order, but without shuffling the elements. Each element might be selected multiple times. Scales well because it does not require caching.- Parameters:
workingRandom- never null, theRandomto use when any random number is needed, soEnvironmentMode.REPRODUCIBLEworks correctly.RandomUtilscan be useful too.- Returns:
- never null
