java.lang.Objectjava.io.OutputStream
com.tangosol.io.WrapperOutputStream
com.tangosol.io.PackedDataOutputStream
public class PackedDataOutputStream
This is an imitation DataOutputStream class that packs its data tighter using variable-length integers and supports UTF longer than 64KB.
Warning! This class is not intended to be thread-safe!

PackedDataOutputStream(OutputStream out)
Construct a PackedDataOutputStream that will output to the specified OutputStream object. |
Method Summary | |
---|---|
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. |
