java.lang.Objectjava.io.OutputStream
com.tangosol.io.WrapperOutputStream
public class WrapperOutputStream
This is an OutputStream class that delegates to another OutputStream. Primarily, this is intended as a base class for building specific-purpose OutputStream wrappers.
Field Summary | |
---|---|
protected OutputStream |
m_out
The underlying OutputStream object to use. |
Constructor Summary | |
---|---|
WrapperOutputStream()
Construct an uninitialized WrapperOutputStream. |
|
WrapperOutputStream(OutputStream out)
Construct a WrapperOutputStream that will output to the specified OutputStream object. |
Method Summary | |
---|---|
void |
close()
Closes this OutputStream and releases any associated system resources. |
protected OutputStream |
ensureOutputStream()
Return the underlying OutputStream. |
void |
flush()
Flushes this OutputStream and forces any buffered output bytes to be written. |
OutputStream |
getOutputStream()
Obtain the underlying OutputStream. |
void |
setOutputStream(OutputStream out)
Specify the underlying OutputStream. |
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 . |
