Method Details

iterator

public Long2LongHashMap.ValueIterator iterator()

Specified by:

iterator in interface Collection<Long>

Specified by:

iterator in interface Iterable<Long>

Specified by:

iterator in class AbstractCollection<Long>

size

public int size()

Specified by:

size in interface Collection<Long>

Specified by:

size in class AbstractCollection<Long>

contains

public boolean contains(Object o)

Specified by:

contains in interface Collection<Long>

Overrides:

contains in class AbstractCollection<Long>

contains

public boolean contains(long value)

Checks if the value is contained in the map.

Parameters:

value - to be checked.

Returns:

true if value is contained in this map.

removeIfLong

public boolean removeIfLong(LongPredicate 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.
