    • Method Detail

      • iterator

        public TLongIterator iterator()
        Creates an iterator over the values of the set. The iterator supports element deletion.
        Specified by:
        iterator in interface  TLongSet
        Specified by:
        iterator in interface  TLongCollection
        Returns:
        an TLongIterator value

      • getNoEntryValue

        public long getNoEntryValue()
        Returns the value that is used to represent null. The default value is generally zero, but can be changed during construction of the collection.
        Specified by:
        getNoEntryValue in interface  TLongSet
        Specified by:
        getNoEntryValue in interface  TLongCollection
        Returns:
        the value that represents null

      • size

        public int size()
        Returns the number of elements in this set (its cardinality). If this set contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.
        Specified by:
        size in interface  TLongSet
        Specified by:
        size in interface  TLongCollection
        Returns:
        the number of elements in this set (its cardinality)

      • isEmpty

        public boolean isEmpty()
        Returns true if this set contains no elements.
        Specified by:
        isEmpty in interface  TLongSet
        Specified by:
        isEmpty in interface  TLongCollection
        Returns:
        true if this set contains no elements

      • contains

        public boolean contains(long entry)
        Returns true if this set contains the specified element.
        Specified by:
        contains in interface  TLongSet
        Specified by:
        contains in interface  TLongCollection
        Parameters:
        entry - an long value
        Returns:
        true if the set contains the specified element.

      • toArray

        public long[] toArray()
        Returns an array containing all of the elements in this set. If this set makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.

        The returned array will be "safe" in that no references to it are maintained by this set. (In other words, this method must allocate a new array even if this set is backed by an array). The caller is thus free to modify the returned array.

        This method acts as bridge between array-based and collection-based APIs.

        Specified by:
        toArray in interface  TLongSet
        Specified by:
        toArray in interface  TLongCollection
        Returns:
        an array containing all the elements in this set

      • toArray

        public long[] toArray(long[] dest)
        Returns an array containing elements in this set.

        If this set fits in the specified array with room to spare (i.e., the array has more elements than this set), the element in the array immediately following the end of the set is set to TLongSet.getNoEntryValue(). (This is useful in determining the length of this set only if the caller knows that this set does not contain any elements representing null.)

        If the native array is smaller than the set size, the array will be filled with elements in Iterator order until it is full and exclude the remainder.

        If this set makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.

        Specified by:
        toArray in interface  TLongSet
        Specified by:
        toArray in interface  TLongCollection
        Parameters:
        dest - the array into which the elements of this set are to be stored.
        Returns:
        an long[] containing all the elements in this set
