Method Details

iterator

public Long2LongHashMap.EntryIterator iterator()

Specified by:

iterator in interface Collection<Map.Entry<Long,Long>>

Specified by:

iterator in interface Iterable<Map.Entry<Long,Long>>

Specified by:

iterator in interface Set<Map.Entry<Long,Long>>

Specified by:

iterator in class AbstractCollection<Map.Entry<Long,Long>>

size

public int size()

Specified by:

size in interface Collection<Map.Entry<Long,Long>>

Specified by:

size in interface Set<Map.Entry<Long,Long>>

Specified by:

size in class AbstractCollection<Map.Entry<Long,Long>>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Collection<Map.Entry<Long,Long>>

Specified by:

isEmpty in interface Set<Map.Entry<Long,Long>>

Overrides:

isEmpty in class AbstractCollection<Map.Entry<Long,Long>>

clear

public void clear()

Specified by:

clear in interface Collection<Map.Entry<Long,Long>>

Specified by:

clear in interface Set<Map.Entry<Long,Long>>

Overrides:

clear in class AbstractCollection<Map.Entry<Long,Long>>

contains

public boolean contains(Object o)

Specified by:

contains in interface Collection<Map.Entry<Long,Long>>

Specified by:

contains in interface Set<Map.Entry<Long,Long>>

Overrides:

contains in class AbstractCollection<Map.Entry<Long,Long>>

removeIfLong

public boolean removeIfLong(LongLongPredicate 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 entry was removed.

toArray

Specified by:

toArray in interface Collection<Map.Entry<Long,Long>>

Specified by:

toArray in interface Set<Map.Entry<Long,Long>>

Overrides:

toArray in class AbstractCollection<Map.Entry<Long,Long>>

toArray

public <T> T[] toArray(T[] a)

Specified by:

toArray in interface Collection<Map.Entry<Long,Long>>

Specified by:

toArray in interface Set<Map.Entry<Long,Long>>

Overrides:

toArray in class AbstractCollection<Map.Entry<Long,Long>>
