接口 ObjectOutput

所有超级接口:

AutoCloseable, DataOutput

所有已知实现类:

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.

从以下版本开始:

JDK1.1

方法详细资料

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.

参数:

obj - the object to be written

抛出:

IOException - Any of the usual Input/Output related exceptions.

write

void write(int b)
    throws IOException

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

指定者:

write 在接口中 DataOutput

参数:

b - the byte

抛出:

IOException - If an I/O error has occurred.

write

void write(byte[] b)
    throws IOException

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

指定者:

write 在接口中 DataOutput

参数:

b - the data to be written

抛出:

IOException - If an I/O error has occurred.

write

void write(byte[] b,
           int off,
           int len)
    throws IOException

Writes a sub array of bytes.

指定者:

write 在接口中 DataOutput

参数:

b - the data to be written

off - the start offset in the data

len - the number of bytes that are written

抛出:

IOException - If an I/O error has occurred.

flush

void flush()
    throws IOException

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

抛出:

IOException - If an I/O error has occurred.

close

void close()
    throws IOException

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

指定者:

close 在接口中 AutoCloseable

抛出:

IOException - If an I/O error has occurred.
