Interface BinaryDataOutput
- All Known Subinterfaces:
RandomAccessIO
- All Known Implementing Classes:
BEBufferedRandomAccessFile,BufferedRandomAccessFile,IISRandomAccessIO,ISRandomAccessIO
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 Details
-
writeByte
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- Throws:
IOException- If an I/O error ocurred.
-
writeShort
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- Throws:
IOException- If an I/O error ocurred.
-
writeInt
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- Throws:
IOException- If an I/O error ocurred.
-
writeLong
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- Throws:
IOException- If an I/O error ocurred.
-
writeFloat
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- Throws:
IOException- If an I/O error ocurred.
-
writeDouble
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- Throws:
IOException- If an I/O error ocurred.
-
getByteOrdering
int getByteOrdering()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.- Returns:
- Either EndianType.BIG_ENDIAN or EndianType.LITTLE_ENDIAN

flush
Any data that has been buffered must be written, and the stream should be realigned at the byte level.- Throws:
IOException- If an I/O error ocurred.
