+ * This class defines four categories of operations upon character buffers:

+ * o Absolute and relative get and put methods that read and write single \
characters; + * o Relative bulk get methods that transfer contiguous sequences of \
characters from + * this buffer into an array; and
+ * o Relative bulk put methods that transfer contiguous sequences of characters \
from + * a character array, a string, or some other character buffer into this \
buffer. + * o Methods for compacting, duplicating, and slicing a character \
buffer. + *
+ * Character buffers can be created either by allocation, which allocates space \
for + * the buffer's content, by wrapping an existing character array or string \
into a + * buffer, or by creating a view of an existing byte buffer
+ *
+ * This class implements the CharSequence interface so that character buffers \
may + * be used wherever character sequences are accepted, for example in the
+ * regular-expression package decaf.util.regex.
+ *
+ * Methods in this class that do not otherwise have a value to return are \
specified + * to return the buffer upon which they are invoked. This allows \
method invocations + * to be chained. The sequence of statements
+ *
+ * cb.put("text/");
+ * cb.put(subtype);
+ * cb.put("; charset=");
+ * cb.put(enc);
+ *
+ * can, for example, be replaced by the single statement
