java.nio: abstract class: CharArrayBuffer

java.nio
abstract class: CharArrayBuffer [javadoc | source]

java.lang.Object
   java.nio.Buffer
      java.nio.CharBuffer
         java.nio.CharArrayBuffer

All Implemented Interfaces:
CharSequence, Comparable, Appendable, Readable

Direct Known Subclasses:
ReadWriteCharArrayBuffer, ReadOnlyCharArrayBuffer

CharArrayBuffer, ReadWriteCharArrayBuffer and ReadOnlyCharArrayBuffer compose the implementation of array based char buffers.

CharArrayBuffer implements all the shared readonly methods and is extended by the other two classes.

All methods are marked final for runtime performance.

Field Summary
protected final char[]	backingArray
protected final int	offset

Fields inherited from java.nio.Buffer:
address

Constructor:
CharArrayBuffer(char[] array) { this(array.length, array, 0); }
CharArrayBuffer(int capacity) { this(capacity, new char[capacity], 0); }
CharArrayBuffer(int capacity, char[] backingArray, int offset) { super(capacity); this.backingArray = backingArray; this.offset = offset; }

Constructor:

 CharArrayBuffer(char[] array) {
        this(array.length, array, 0);
}

 CharArrayBuffer(int capacity) {
        this(capacity, new char[capacity], 0);
}

 CharArrayBuffer(int capacity,
    char[] backingArray,
    int offset) {
        super(capacity);
        this.backingArray = backingArray;
        this.offset = offset;
}
