Method Details

iterator

public Int2IntHashMap.ValueIterator iterator()

Specified by:

iterator in interface Collection<Integer>

Specified by:

iterator in interface Iterable<Integer>

Specified by:

iterator in class AbstractCollection<Integer>

size

public int size()

Specified by:

size in interface Collection<Integer>

Specified by:

size in class AbstractCollection<Integer>

contains

public boolean contains(Object o)

Specified by:

contains in interface Collection<Integer>

Overrides:

contains in class AbstractCollection<Integer>

contains

public boolean contains(int value)

Checks if the value is contained in the map.

Parameters:

value - to be checked.

Returns:

true if value is contained in this map.

removeIfInt

public boolean removeIfInt(IntPredicate filter)

Removes all the elements of this collection that satisfy the given predicate.

NB: Renamed from removeIf to avoid overloading on parameter types of lambda expression, which doesn't play well with type inference in lambda expressions.

Parameters:

filter - a predicate to apply.

Returns:

true if at least one value was removed.
