- All Implemented Interfaces:
IntSet
public class MonotonicIntSet extends java.lang.Object implements IntSet
Set of int values. This implementation requires that new entries are added in monotonically increasing order; any attempt to add a value out of sequence, or to remove a value, results is an UnsupportedOperationException

Method Detail
-
copy
public IntSet copy()
Description copied from interface:IntSetCreate a copy of this IntSet that leaves the original unchanged.
-
mutableCopy
public IntSet mutableCopy()
Description copied from interface:IntSetCreate a copy of this IntSet that contains the same set of integers.- Specified by:
mutableCopyin interfaceIntSet- Returns:
- an IntSet containing the same integers. The result will not necessarily be the same class as the original. It will always be a mutable object
-
isMutable
public boolean isMutable()
Description copied from interface:IntSetAsk whether the set permits in-situ modifications using add() and remove()
-
clear
public void clear()
Description copied from interface:IntSetClear the contents of the IntSet (making it an empty set)
-
size
public int size()
Description copied from interface:IntSetGet the number of integers in the set
-
isEmpty
public boolean isEmpty()
Description copied from interface:IntSetDetermine if the set is empty
-
contains
public boolean contains(int value)
Description copied from interface:IntSetDetermine whether a particular integer is present in the set
-
remove
public boolean remove(int value)
Description copied from interface:IntSetRemove an integer from the set
-
add
public boolean add(int value)
Add an integer to the set- Specified by:
addin interfaceIntSet- Parameters:
value- the integer to be added (which must be greater than or equal to the largest integer currently in the set)- Returns:
- true if the integer was added, false if it was already present
- Throws:
java.lang.UnsupportedOperationException- if the set already contains an integer larger than the supplied value
-
iterator
public IntIterator iterator()
Get an iterator over the values
-
union
public IntSet union(IntSet other)
Form a new set that is the union of this set with another set.
-
make
public static MonotonicIntSet make(int[] in, int size)
Factory method to construct a set from an array of integers- Parameters:
in- the array of integers, which must be in ascending ordersize- the number of elements in the array that are significant- Returns:
- the constructed set
-
toString
public java.lang.String toString()
- Overrides:
toStringin classjava.lang.Object
-
equals
public boolean equals(java.lang.Object other)
Test whether this set has exactly the same members as another set- Overrides:
equalsin classjava.lang.Object
-
hashCode
public int hashCode()
Construct a hash key that supports the equals() test- Overrides:
hashCodein classjava.lang.Object
