Interface ObjectOutput

- All Superinterfaces:
- AutoCloseable, DataOutput
- All Known Implementing Classes:
- ObjectOutputStream
public interface ObjectOutput extends DataOutput, AutoCloseable
ObjectOutput extends the DataOutput interface to include writing of objects. DataOutput includes methods for output of primitive types, ObjectOutput extends that interface to include objects, arrays, and Strings.- Since:
- JDK1.1

Method Detail
writeObject
void writeObject(Object obj) throws IOException
Write an object to the underlying storage or stream. The class that implements this interface defines how the object is written.- Parameters:
-
obj- the object to be written - Throws:
-
IOException- Any of the usual Input/Output related exceptions.
write
void write(int b) throws IOExceptionWrites a byte. This method will block until the byte is actually written.- Specified by:
-
writein interfaceDataOutput - Parameters:
-
b- the byte - Throws:
-
IOException- If an I/O error has occurred.
write
void write(byte[] b) throws IOExceptionWrites an array of bytes. This method will block until the bytes are actually written.- Specified by:
-
writein interfaceDataOutput - Parameters:
-
b- the data to be written - Throws:
-
IOException- If an I/O error has occurred.
write
void write(byte[] b, int off, int len) throws IOExceptionWrites a sub array of bytes.- Specified by:
-
writein interfaceDataOutput - Parameters:
-
b- the data to be written -
off- the start offset in the data -
len- the number of bytes that are written - Throws:
-
IOException- If an I/O error has occurred.
flush
void flush() throws IOExceptionFlushes the stream. This will write any buffered output bytes.- Throws:
-
IOException- If an I/O error has occurred.
close
void close() throws IOExceptionCloses the stream. This method must be called to release any resources associated with the stream.- Specified by:
-
closein interfaceAutoCloseable - Throws:
-
IOException- If an I/O error has occurred.
