java.lang.Object
java.io.OutputStream
com.tangosol.io.WrapperDataOutputStream
public class WrapperDataOutputStream
This is an imitation DataOutputStream class that provides the DataOutput interface by delegating to an object that implements the DataOutput interface. Primarily, this is intended as a base class for building specific-purpose DataOutput wrappers.
Constructor Summary | |
---|---|
WrapperDataOutputStream(java.io.DataOutput out) Construct a WrapperDataOutputStream that will output to the specified object implementing the DataOutput interface. |
Method Summary | |
---|---|
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. |
java.io.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(java.lang.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(java.lang.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(java.lang.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. |
