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).
See Also:   EndianType





Method Summary
public  voidflush()
     Any data that has been buffered must be written, and the stream should be realigned at the byte level.
public  intgetByteOrdering()
     Returns the endianness (i.e., byte ordering) of the implementing class.
public  voidwriteByte(int v)
     Should write the byte value of v (i.e., 8 least significant bits) to the output.
public  voidwriteDouble(double v)
     Should write the IEEE double value v (i.e., 64 bits) to the output.
public  voidwriteFloat(float v)
     Should write the IEEE float value v (i.e., 32 bits) to the output.
public  voidwriteInt(int v)
     Should write the int value of v (i.e., the 32 bits) to the output.
public  voidwriteLong(long v)
     Should write the long value of v (i.e., the 64 bits) to the output.
public  voidwriteShort(int v)
     Should write the short value of v (i.e., 16 least significant bits) to the output.



Method Detail
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
See Also:   EndianType



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.
