Method Detail

getNoEntryValue

byte 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.

Returns:

the value that represents null

size

int size()

Returns the number of elements in this collection (its cardinality). If this collection contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

Returns:

the number of elements in this collection (its cardinality)

isEmpty

boolean isEmpty()

Returns true if this collection contains no elements.

Returns:

true if this collection contains no elements

contains

boolean contains(byte entry)

Returns true if this collection contains the specified element.

Parameters:

entry - an byte value

Returns:

true if the collection contains the specified element.

iterator

TByteIterator iterator()

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

Returns:

an TByteIterator value

toArray

byte[] toArray()

Returns an array containing all of the elements in this collection. If this collection 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 collection. (In other words, this method must allocate a new array even if this collection 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.

Returns:

an array containing all the elements in this collection

toArray

byte[] toArray(byte[] dest)

Returns an array containing elements in this collection.

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

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

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

Parameters:

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

Returns:

an byte[] containing all the elements in this collection

Throws:

java.lang.NullPointerException - if the specified array is null

add

boolean add(byte entry)

Inserts a value into the collection.

Parameters:

entry - a byte value

Returns:

true if the collection was modified by the add operation

remove

boolean remove(byte entry)

Removes entry from the collection.

Parameters:

entry - an byte value

Returns:

true if the collection was modified by the remove operation.

containsAll

boolean containsAll(java.util.Collection<?> collection)

Tests the collection to determine if all of the elements in collection are present.

Parameters:

collection - a Collection value

Returns:

true if all elements were present in the collection.

containsAll

boolean containsAll(TByteCollection collection)

Tests the collection to determine if all of the elements in TByteCollection are present.

Parameters:

collection - a TByteCollection value

Returns:

true if all elements were present in the collection.

containsAll

boolean containsAll(byte[] array)

Tests the collection to determine if all of the elements in array are present.

Parameters:

array - as array of byte primitives.

Returns:

true if all elements were present in the collection.

addAll

boolean addAll(java.util.Collection<? extends java.lang.Byte> collection)

Adds all of the elements in collection to the collection.

Parameters:

collection - a Collection value

Returns:

true if the collection was modified by the add all operation.

addAll

boolean addAll(TByteCollection collection)

Adds all of the elements in the TByteCollection to the collection.

Parameters:

collection - a TByteCollection value

Returns:

true if the collection was modified by the add all operation.

addAll

boolean addAll(byte[] array)

Adds all of the elements in the array to the collection.

Parameters:

array - a array of byte primitives.

Returns:

true if the collection was modified by the add all operation.

retainAll

boolean retainAll(java.util.Collection<?> collection)

Removes any values in the collection which are not contained in collection.

Parameters:

collection - a Collection value

Returns:

true if the collection was modified by the retain all operation

retainAll

boolean retainAll(TByteCollection collection)

Removes any values in the collection which are not contained in TByteCollection.

Parameters:

collection - a TByteCollection value

Returns:

true if the collection was modified by the retain all operation

retainAll

boolean retainAll(byte[] array)

Removes any values in the collection which are not contained in array.

Parameters:

array - an array of byte primitives.

Returns:

true if the collection was modified by the retain all operation

removeAll

boolean removeAll(java.util.Collection<?> collection)

Removes all of the elements in collection from the collection.

Parameters:

collection - a Collection value

Returns:

true if the collection was modified by the remove all operation.

removeAll

boolean removeAll(TByteCollection collection)

Removes all of the elements in TByteCollection from the collection.

Parameters:

collection - a TByteCollection value

Returns:

true if the collection was modified by the remove all operation.

removeAll

boolean removeAll(byte[] array)

Removes all of the elements in array from the collection.

Parameters:

array - an array of byte primitives.

Returns:

true if the collection was modified by the remove all operation.

clear

void clear()

Empties the collection.

forEach

boolean forEach(TByteProcedure procedure)

Executes procedure for each element in the collection.

Parameters:

procedure - a TByteProcedure value

Returns:

false if the loop over the collection terminated because the procedure returned false for some value.

equals

boolean equals(java.lang.Object o)

Compares the specified object with this collection for equality. Returns true if the specified object is also a collection, the two collection have the same size, and every member of the specified collection is contained in this collection (or equivalently, every member of this collection is contained in the specified collection). This definition ensures that the equals method works properly across different implementations of the collection interface.

Overrides:

equals in class java.lang.Object

Parameters:

o - object to be compared for equality with this collection

Returns:

true if the specified object is equal to this collection

hashCode

int hashCode()

Returns the hash code value for this collection. The hash code of a collection is defined to be the sum of the hash codes of the elements in the collection. This ensures that s1.equals(s2) implies that s1.hashCode()==s2.hashCode() for any two collection s1 and s2, as required by the general contract of Object.hashCode().

Overrides:

hashCode in class java.lang.Object

Returns:

the hash code value for this collection
