java.lang.Objectcom.ibm.icu.util.ByteArrayWrapper
public class ByteArrayWrapper
A simple utility class to wrap a byte array.
Generally passed as an argument object into a method. The method takes responsibility of writing into the internal byte array and increasing its size when necessary.
Field Summary | |
---|---|
byte[] |
bytes
Internal byte array. |
int |
size
Size of the internal byte array used. |
Constructor Summary | |
---|---|
ByteArrayWrapper()
Construct a new ByteArrayWrapper with no data. |
|
ByteArrayWrapper(byte[] bytesToAdopt,
int size)
Construct a new ByteArrayWrapper from a byte array and size |
|
ByteArrayWrapper(ByteBuffer source)
Construct a new ByteArrayWrapper from the contents of a ByteBuffer. |
Method Summary | |
---|---|
ByteArrayWrapper |
append(byte[] src,
int start,
int limit)
Appends the internal byte array from offset size with the contents of src from offset start to limit. |
int |
compareTo(Object other)
Compare this object to another ByteArrayWrapper, which must not be null. |
ByteArrayWrapper |
ensureCapacity(int capacity)
Ensure that the internal byte array is at least of length capacity. |
boolean |
equals(Object other)
Return true if the bytes in each wrapper are equal. |
int |
hashCode()
Return the hashcode. |
byte[] |
releaseBytes()
Releases the internal byte array to the caller, resets the internal byte array to null and its size to 0. |
ByteArrayWrapper |
set(byte[] src,
int start,
int limit)
Set the internal byte array from offset 0 to (limit - start) with the contents of src from offset start to limit. |
String |
toString()
Returns string value for debugging |
