Interface ObjectOutput

All Superinterfaces:

DataOutput

All Known Implementing Classes:

ObjectOutputStream

public interface ObjectOutput
extends DataOutput

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

Suppressed. default deny

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 IOException

Suppressed. default deny

Writes a byte. This method will block until the byte is actually written.

Specified by:

write in interface DataOutput

Parameters:

b - the byte

Throws:

IOException - If an I/O error has occurred.

write

void write(byte[] b)
           throws IOException

Suppressed. default deny

Writes an array of bytes. This method will block until the bytes are actually written.

Specified by:

write in interface DataOutput

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 IOException

Suppressed. default deny

Writes a sub array of bytes.

Specified by:

write in interface DataOutput

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 IOException

Suppressed. default deny

Flushes the stream. This will write any buffered output bytes.

Throws:

IOException - If an I/O error has occurred.

close

void close()
           throws IOException

Suppressed. default deny

Closes the stream. This method must be called to release any resources associated with the stream.

Throws:

IOException - If an I/O error has occurred.
