Method Detail

iterator

public TFloatIterator iterator()

Creates an iterator over the values of the set. The iterator supports element deletion.

Specified by:

iterator in interface TFloatSet

Specified by:

iterator in interface TFloatCollection

Returns:

an TFloatIterator value

getNoEntryValue

public float 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 TFloatSet

Specified by:

getNoEntryValue in interface TFloatCollection

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 TFloatSet

Specified by:

size in interface TFloatCollection

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 TFloatSet

Specified by:

isEmpty in interface TFloatCollection

Returns:

true if this set contains no elements

contains

public boolean contains(float entry)

Returns true if this set contains the specified element.

Specified by:

contains in interface TFloatSet

Specified by:

contains in interface TFloatCollection

Parameters:

entry - an float value

Returns:

true if the set contains the specified element.

toArray

public float[] 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 TFloatSet

Specified by:

toArray in interface TFloatCollection

Returns:

an array containing all the elements in this set

toArray

public float[] toArray(float[] 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 TFloatSet.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 TFloatSet

Specified by:

toArray in interface TFloatCollection

Parameters:

dest - the array into which the elements of this set are to be stored.

Returns:

an float[] containing all the elements in this set

equals

public boolean equals(java.lang.Object other)
