|---|---|
void |

|
int |
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 v)
Writes a
boolean to the underlying output stream as
a 1-byte value. |
void |
writeByte(int v)
Writes out a
byte to the underlying output stream as
a 1-byte value. |
void |
writeBytes(String s)
Writes out the string to the underlying output stream as a
sequence of bytes.
|
void |
writeChar(int v)
Writes a
char to the underlying output stream as a
2-byte value, high byte first. |
void |
writeChars(String s)
Writes a string to the underlying output stream as a sequence of
characters.
|
void |
writeDouble(double v)
Converts the double argument 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, high byte first. |
void |
writeFloat(float v)
Converts the float argument 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, high byte first. |
void |
writeInt(int v)
Writes an
int to the underlying output stream as four
bytes, low byte first. |
void |
writeLong(long v)
Writes a
long to the underlying output stream as eight
bytes, high byte first. |
void |
writeShort(int v)
Writes a
short to the underlying output stream as two
bytes, low byte first. |
void |
writeUTF(String str)
Writes a string to the underlying output stream using
modified UTF-8
encoding in a machine-independent manner.

First, two bytes are written to the output stream as if by the
writeShort method giving the number of bytes to
follow. This value is the number of bytes actually written out,
not the length of the string. Following the length, each character
of the string is output, in sequence, using the modified UTF-8 encoding
for the character. If no exception is thrown, the counter
written is incremented by the total number of
bytes written to the output stream. This will be at least two
plus the length of str, and at most two plus
thrice the length of str.
