 com.ibm.icu.util.ByteArrayWrapper
All known Subclasses: com.ibm.icu.text.RawCollationKey,
| ByteArrayWrapper | | public class ByteArrayWrapper implements Comparable(Code) | |
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 | |
| public byte[] | bytes
Internal byte array. | | public int | size
Size of the internal byte array used. |
| Constructor Summary | |
| public | ByteArrayWrapper()
Construct a new ByteArrayWrapper with no data. | | public | ByteArrayWrapper(byte[] bytesToAdopt, int size)
| | public | ByteArrayWrapper(ByteBuffer source)
Construct a new ByteArrayWrapper from the contents of a ByteBuffer. |
| Method Summary | |
| final public 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. | | public int | compareTo(Object other)
Compare this object to another ByteArrayWrapper, which must not be null.
Parameters:
other - the object to compare to. | | public ByteArrayWrapper | ensureCapacity(int capacity)
Ensure that the internal byte array is at least of length capacity. | | public boolean | equals(Object other)
Return true if the bytes in each wrapper are equal.
Parameters:
other - the object to compare to. | | public int | hashCode()
Return the hashcode. | | final public byte[] | releaseBytes()
Releases the internal byte array to the caller, resets the internal
byte array to null and its size to 0. | | final public 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. | | public String | toString()
|
| bytes | | public byte[] bytes(Code) | | Internal byte array.
|
| size | | public int size(Code) | | Size of the internal byte array used.
Different from bytes.length, size will be <= bytes.length.
Semantics of size is similar to java.util.Vector.size().
|
| ByteArrayWrapper | | public ByteArrayWrapper()(Code) | | Construct a new ByteArrayWrapper with no data.
|
| ByteArrayWrapper | | public ByteArrayWrapper(byte[] bytesToAdopt, int size)(Code) | | Construct a new ByteArrayWrapper from a byte array and size
Parameters:
bytesToAdopt - the byte array to adopt
Parameters:
size - the length of valid data in the byte array
throws:
IndexOutOfBoundsException - if bytesToAdopt == null and size != 0, orsize < 0, or size > bytesToAdopt.length. |
| ByteArrayWrapper | | public ByteArrayWrapper(ByteBuffer source)(Code) | | Construct a new ByteArrayWrapper from the contents of a ByteBuffer.
Parameters:
source - the ByteBuffer from which to get the data. |
| append | | final public ByteArrayWrapper append(byte[] src, int start, int limit)(Code) | | Appends the internal byte array from offset size with the
contents of src from offset start to limit. This increases the size of
the internal byte array to (size + limit - start).
Parameters:
src - source byte array to copy from
Parameters:
start - start offset of src to copy from
Parameters:
limit - end + 1 offset of src to copy from this ByteArrayWrapper |
| compareTo | | public int compareTo(Object other)(Code) | | Compare this object to another ByteArrayWrapper, which must not be null.
Parameters:
other - the object to compare to. a value <0, 0, or >0 as this compares less than, equal to, orgreater than other.
throws:
ClassCastException - if the other object is not a ByteArrayWrapper |
| ensureCapacity | | public ByteArrayWrapper ensureCapacity(int capacity)(Code) | | Ensure that the internal byte array is at least of length capacity.
If the byte array is null or its length is less than capacity, a new
byte array of length capacity will be allocated.
The contents of the array (between 0 and size) remain unchanged.
Parameters:
capacity - minimum length of internal byte array. this ByteArrayWrapper |
| equals | | public boolean equals(Object other)(Code) | | Return true if the bytes in each wrapper are equal.
Parameters:
other - the object to compare to. true if the two objects are equal. |
| hashCode | | public int hashCode()(Code) | | Return the hashcode.
the hashcode. |
| releaseBytes | | final public byte[] releaseBytes()(Code) | | Releases the internal byte array to the caller, resets the internal
byte array to null and its size to 0.
internal byte array. |
| set | | final public ByteArrayWrapper set(byte[] src, int start, int limit)(Code) | | Set the internal byte array from offset 0 to (limit - start) with the
contents of src from offset start to limit. If the byte array is null or its length is less than capacity, a new
byte array of length (limit - start) will be allocated.
This resets the size of the internal byte array to (limit - start).
Parameters:
src - source byte array to copy from
Parameters:
start - start offset of src to copy from
Parameters:
limit - end + 1 offset of src to copy from this ByteArrayWrapper |
| toString | | public String toString()(Code) | | Returns string value for debugging
