public class LEDataOutputStream extends DecoratingOutputStream implements java.io.DataOutput
This class is similar to DataOutputStream,
but writes data in Little Endian format to its underlying stream.
A noteable difference to DataOutputStream is that the
size() method and the written field are respectively
return long values and wrap to Long.MAX_VALUE.
Note that this class is not thread safe.

LEDataOutputStream(java.io.OutputStream out)
Creates a new data output stream to write data to the specified
underlying output stream.
|
| Modifier and Type | Method and Description |
|---|---|
private void |
incCount(int inc)
Increases the written counter by the specified value
until it reaches
Long.MAX_VALUE. |
long |
size()
Returns the current value of the counter
written,
the number of bytes written to this data output stream so far. |
void |
write(byte[] b,
int off,
int len)
Writes
len bytes from the specified byte array
starting at offset off to the underlying output stream. |
void |
write(int b)
Writes the specified byte (the low eight bits of the argument
b) to the underlying output stream. |
void |
writeBoolean(boolean b)
Writes a
boolean value to the underlying output stream
as a 1-byte value. |
void |
writeByte(int b)
Writes a
byte value to the underlying output stream
as a 1-byte value. |
void |
writeBytes(java.lang.String s)
Writes the string
s to the underlying output stream as a
sequence of bytes. |
void |
writeChar(int c)
Writes a
char value to the underlying output stream
as a 2-byte value, low byte first. |
void |
writeChars(java.lang.String s)
Writes the string
s to the underlying output stream as a
sequence of characters. |
void |
writeDouble(double d)
Converts the double value
d to a long using
the doubleToLongBits method in class Double,
and then writes that long value to the underlying
output stream as an 8-byte quantity, low byte first. |
void |
writeFloat(float f)
Converts the float value
f to an int using
the floatToIntBits method in class Float,
and then writes that int value to the underlying
output stream as a 4-byte quantity, low byte first. |
void |
writeInt(int i)
Writes the integer value
i to the underlying output stream
as four bytes, low byte first. |
void |
writeLong(long l)
Writes the integer value
l to the underlying output stream
as eight bytes, low byte first. |
void |
writeShort(int s)
Writes the integer value
s to the underlying output stream
as two bytes, low byte first. |
void |
writeUTF(java.lang.String str)
This method is not implemented.
