public class WrapperDataOutputStream extends OutputStream implements DataOutput, OutputStreaming
Constructor and Description |
---|
WrapperDataOutputStream(DataOutput out)
Construct a WrapperDataOutputStream that will output to the specified object implementing the DataOutput interface.
|
Modifier and Type | Method and Description |
---|---|
void |
close()
Closes this OutputStream and releases any associated system resources.
|
void |
flush()
Flushes this OutputStream and forces any buffered output bytes to be written.
|
long |
getBytesWritten()
Return the total number of bytes written to the wrapped DataOutput object.
|
DataOutput |
getDataOutput()
Obtain the underlying object providing the DataOutput interface that this object is delegating to.
|
protected void |
incBytesWritten(int cb)
Increment the count of total number of bytes written to the wrapped DataOutput object by the specified number of bytes.
|
void |
write(byte[] ab)
Writes all the bytes in the array
ab . |
void |
write(byte[] ab, int of, int cb)
Writes
cb bytes starting at offset of from the array ab . |
void |
write(int b)
Writes the eight low-order bits of the argument
b . |
void |
writeBoolean(boolean f)
Writes the boolean value
f . |
void |
writeByte(int b)
Writes the eight low-order bits of the argument
b . |
void |
writeBytes(String s)
Writes the String
s , but only the low-order byte from each character of the String is written. |
void |
writeChar(int ch)
Writes a char value, comprised of the 16 low-order bits of the argument
ch ; the 16 high-order bits of ch are ignored. |
void |
writeChars(String s)
Writes the String
s as a sequence of characters. |
void |
writeDouble(double dfl)
Writes a double value.
|
void |
writeFloat(float fl)
Writes a float value.
|
void |
writeInt(int n)
Writes an int value.
|
void |
writeLong(long l)
Writes a long value.
|
void |
writeShort(int n)
Writes a short value, comprised of the 16 low-order bits of the argument
n ; the 16 high-order bits of n are ignored. |
void |
writeUTF(String s)
Writes the String
s as a sequence of characters, but using UTF-8 encoding for the characters, and including the String length data so that the corresponding DataInput.readUTF() method can reconstitute a String from the written data. |
