XByteIndexedList (Talon 3.14.19 API)

java.lang.Object
- com.neeve.lang.XByteCollectionBase
- - com.neeve.lang.XByteIndexedList

All Implemented Interfaces:

XByteCollection, XByteList, RandomAccess
```
public class XByteIndexedList
extends XByteCollectionBase
implements XByteList, RandomAccess
```
This class represents a random access collection with real-time behavior (smooth capacity increase) for a primitivive list of bytes

This class has the following advantages over the widely used java.util.ArrayList:
- No large array allocation (for large collections multi-dimensional arrays are employed). The garbage collector is not stressed with large chunk of memory to allocate (likely to trigger a full garbage collection due to memory fragmentation).
- No autoboxing garbage associate with converting between primitive byte and Byte.
- Support concurrent access/iteration/modification without synchronization if marked shared.
Iterations over the XByteIndexedList values are faster when performed using the get(int) method rather than using collection records or iterators:[code] for (int i = 0, n = list.size(); i < n; i++) { list.get(i); }[/code]

This class was based on collections code from http://javolution.org, but modified for use outside of realtime jvms.

Constructor Summary

Constructors
Constructor and Description
`XByteIndexedList()` Creates a list of small initial capacity.
`XByteIndexedList(int capacity)` Creates a list of specified initial capacity; unless the list size reaches the specified capacity, operations on this list will not allocate memory (no lazy object creation).
`XByteIndexedList(XByteCollection values)` Creates a list containing the specified values, in the order they are returned by the collection's iterator.

  indexOf public final int indexOf(byte value) Returns the index in this list of the first occurrence of the specified value, or -1 if this list does not contain this value. Specified by: indexOf in interface XByteList Parameters: value - the value to search for. Returns: the index in this list of the first occurrence of the specified value, or -1 if this list does not contain this value. lastIndexOf public final int lastIndexOf(byte value) Returns the index in this list of the last occurrence of the specified value, or -1 if this list does not contain this value. Specified by: lastIndexOf in interface XByteList Parameters: value - the value to search for. Returns: the index in this list of the last occurrence of the specified value, or -1 if this list does not contain this value. iterator public XByteIterator iterator() Returns an iterator over the elements in this list Specified by: iterator in interface XByteCollection Specified by: iterator in interface XByteList Overrides: iterator in class XByteCollectionBase Returns: an iterator over this list values. listIterator public XByteListIterator listIterator() Returns a list iterator over the elements in this list Specified by: listIterator in interface XByteList Returns: an iterator over this list values. listIterator public XByteListIterator listIterator(int index) Returns a list iterator from the specified position Specified by: listIterator in interface XByteList Parameters: index - the index of first value to be returned from the list iterator (by a call to the next method). Returns: a list iterator of the values in this list starting at the specified position in this list. Throws: IndexOutOfBoundsException - if the index is out of range [code](index < 0 || index > size())[/code] subList public final XByteList subList(int fromIndex, int toIndex) Returns a view of the portion of this list between the specified If the specified indexes are equal, the returned list is empty. The returned list is backed by this list, so non-structural changes in the returned list are reflected in this list, and vice-versa. This method eliminates the need for explicit range operations (of the sort that commonly exist for arrays). Any operation that expects a list can be used as a range operation by passing a subList view instead of a whole list. For example, the following idiom removes a range of values from a list: [code] list.subList(from, to).clear();[/code] Similar idioms may be constructed for indexOf and lastIndexOf, and all of the algorithms in the Collections class can be applied to a subList. The semantics of the list returned by this method become undefined if the backing list (i.e., this list) is structurally modified in any way other than via the returned list (structural modifications are those that change the size of this list, or otherwise perturb it in such a fashion that iterations in progress may yield incorrect results). Specified by: subList in interface XByteList Parameters: fromIndex - low endpoint (inclusive) of the subList. toIndex - high endpoint (exclusive) of the subList. Returns: a view of the specified range within this list. Throws: IndexOutOfBoundsException - if [code](fromIndex < 0 || toIndex > size || fromIndex > toIndex)[/code] trimToSize public final void trimToSize() Reduces the capacity of this list to the current size (minimize storage space). sort public void sort(boolean ascending) size public final int size() Description copied from class: XByteCollectionBase Returns the number of values in this collection. Specified by: size in interface XByteCollection Specified by: size in interface XByteList Specified by: size in class XByteCollectionBase Returns: the number of values. head public final XCollection.Record head() Description copied from class: XByteCollectionBase Returns the head record of this collection; it is the record such as head().getNext() holds the first collection value. Specified by: head in interface XByteCollection Specified by: head in class XByteCollectionBase Returns: the head record. tail public final XCollection.Record tail() Description copied from class: XByteCollectionBase Returns the tail record of this collection; it is the record such as tail().getPrevious() holds the last collection value. Specified by: tail in interface XByteCollection Specified by: tail in class XByteCollectionBase Returns: the tail record. valueOf public final byte valueOf(XCollection.Record record) Description copied from class: XByteCollectionBase Returns the collection value for the specified record. Specified by: valueOf in interface XByteCollection Specified by: valueOf in class XByteCollectionBase Parameters: record - the record whose current value is returned. Returns: the current value. delete public final void delete(XCollection.Record record) Description copied from class: XByteCollectionBase Deletes the specified record from this collection. Implementation must ensure that removing a record from the collection does not affect in any way the records preceding the record being removed (it might affect the next records though, e.g. in a list collection, the indices of the subsequent records will change). Specified by: delete in interface XByteCollection Specified by: delete in class XByteCollectionBase Parameters: record - the record to be removed. unmodifiable public XByteList unmodifiable() Description copied from class: XByteCollectionBase Returns the unmodifiable view associated to this collection. Attempts to modify the returned collection result in an UnsupportedOperationException being thrown. Specified by: unmodifiable in interface XByteCollection Overrides: unmodifiable in class XByteCollectionBase Returns: the unmodifiable view over this collection. contains public final boolean contains(byte value) Description copied from class: XByteCollectionBase Indicates if this collection contains the specified value. Specified by: contains in interface XByteCollection Specified by: contains in interface XByteList Overrides: contains in class XByteCollectionBase Parameters: value - the value whose presence in this collection is to be tested. Returns: true if this collection contains the specified value;false otherwise.
