| jj2000.j2k.io.BinaryDataOutput
| BinaryDataOutput | | public interface BinaryDataOutput (Code) | | This interface defines the output of binary data to streams and/or files.
Byte level output (i.e., for byte, int, long, float, etc.) should
always be byte aligned. For example, a request to write an
int should always realign the output at the byte level.
The implementation of this interface should clearly define if
multi-byte output data is written in little- or big-endian byte
ordering (least significant byte first or most significant byte
first, respectively).

| Method Summary | |
| public void | flush()
Any data that has been buffered must be written, and the stream should
be realigned at the byte level. | | public int | getByteOrdering()
Returns the endianness (i.e., byte ordering) of the implementing
class. | | public void | writeByte(int v)
Should write the byte value of v (i.e., 8 least
significant bits) to the output. | | public void | writeDouble(double v)
Should write the IEEE double value v (i.e., 64 bits)
to the output. | | public void | writeFloat(float v)
Should write the IEEE float value v (i.e., 32 bits) to
the output. | | public void | writeInt(int v)
Should write the int value of v (i.e., the 32 bits) to
the output. | | public void | writeLong(long v)
Should write the long value of v (i.e., the 64 bits)
to the output. | | public void | writeShort(int v)
Should write the short value of v (i.e., 16 least
significant bits) to the output. |
| flush | | public void flush() throws IOException(Code) | | Any data that has been buffered must be written, and the stream should
be realigned at the byte level.
exception:
IOException - If an I/O error ocurred. |
| getByteOrdering | | public int getByteOrdering()(Code) | | Returns the endianness (i.e., byte ordering) of the implementing
class. Note that an implementing class may implement only one
type of endianness or both, which would be decided at creatiuon
time.
Either EndianType.BIG_ENDIAN orEndianType.LITTLE_ENDIAN

| writeByte | | public void writeByte(int v) throws IOException(Code) | | Should write the byte value of v (i.e., 8 least
significant bits) to the output. Prior to writing, the output
should be realigned at the byte level.
Signed or unsigned data can be written. To write a signed
value just pass the byte value as an argument. To
write unsigned data pass the int value as an argument
(it will be automatically casted, and only the 8 least
significant bits will be written).
Parameters:
v - The value to write to the output
exception:
IOException - If an I/O error ocurred. |
| writeDouble | | public void writeDouble(double v) throws IOException(Code) | | Should write the IEEE double value v (i.e., 64 bits)
to the output. Prior to writing, the output should be realigned
at the byte level.
Parameters:
v - The value to write to the output
exception:
IOException - If an I/O error ocurred. |
| writeFloat | | public void writeFloat(float v) throws IOException(Code) | | Should write the IEEE float value v (i.e., 32 bits) to
the output. Prior to writing, the output should be realigned at
the byte level.
Parameters:
v - The value to write to the output
exception:
IOException - If an I/O error ocurred. |
| writeInt | | public void writeInt(int v) throws IOException(Code) | | Should write the int value of v (i.e., the 32 bits) to
the output. Prior to writing, the output should be realigned at
the byte level.
Parameters:
v - The value to write to the output
exception:
IOException - If an I/O error ocurred. |
| writeLong | | public void writeLong(long v) throws IOException(Code) | | Should write the long value of v (i.e., the 64 bits)
to the output. Prior to writing, the output should be realigned
at the byte level.
Parameters:
v - The value to write to the output
exception:
IOException - If an I/O error ocurred. |
| writeShort | | public void writeShort(int v) throws IOException(Code) | | Should write the short value of v (i.e., 16 least
significant bits) to the output. Prior to writing, the output
should be realigned at the byte level.
Signed or unsigned data can be written. To write a signed
value just pass the short value as an argument. To
write unsigned data pass the int value as an argument
(it will be automatically casted, and only the 16 least
significant bits will be written).
Parameters:
v - The value to write to the output
exception:
IOException - If an I/O error ocurred. |
