ObjectOutput

public interface ObjectOutput
implements DataOutput, AutoCloseable

java.io.ObjectOutput

Known Indirect Subclasses

ObjectOutputStream

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.

`abstract void`	`write(byte[] b)` Writes to the output stream all the bytes in array `b`.
`abstract void`	`write(byte[] b, int off, int len)` Writes `len` bytes from array `b`, in order, to the output stream.
`abstract void`	`write(int b)` Writes to the output stream the eight low-order bits of the argument `b`.
`abstract void`	`writeBoolean(boolean v)` Writes a `boolean` value to this output stream.
`abstract void`	`writeByte(int v)` Writes to the output stream the eight low- order bits of the argument `v`.
`abstract void`	`writeBytes(String s)` Writes a string to the output stream.
`abstract void`	`writeChar(int v)` Writes a `char` value, which is comprised of two bytes, to the output stream.
`abstract void`	`writeChars(String s)` Writes every character in the string `s`, to the output stream, in order, two bytes per character.
`abstract void`	`writeDouble(double v)` Writes a `double` value, which is comprised of eight bytes, to the output stream.
`abstract void`	`writeFloat(float v)` Writes a `float` value, which is comprised of four bytes, to the output stream.
`abstract void`	`writeInt(int v)` Writes an `int` value, which is comprised of four bytes, to the output stream.
`abstract void`	`writeLong(long v)` Writes a `long` value, which is comprised of eight bytes, to the output stream.
`abstract void`	`writeShort(int v)` Writes two bytes to the output stream to represent the value of the argument.
`abstract void`	`writeUTF(String s)` Writes two bytes of length information to the output stream, followed by the modified UTF-8 representation of every character in the string `s`.

From interface


  
    java.lang.AutoCloseable

Public methods

close

Added in API level 1

void close ()

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.

flush

Added in API level 1

void flush ()

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

Throws
`IOException`	If an I/O error has occurred.

write

Added in API level 1

void write (byte[] b)

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

Parameters
`b`	`byte`: the data to be written

Throws
`IOException`	If an I/O error has occurred.

write

Added in API level 1

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

Writes a sub array of bytes.

Parameters
`b`	`byte`: the data to be written
`off`	`int`: the start offset in the data
`len`	`int`: the number of bytes that are written

Throws
`IOException`	If an I/O error has occurred.

write

Added in API level 1

void write (int b)

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

Parameters
`b`	`int`: the byte

Throws
`IOException`	If an I/O error has occurred.

writeObject

Added in API level 1

void writeObject (Object obj)

Write an object to the underlying storage or stream. The class that implements this interface defines how the object is written.

Parameters
`obj`	`Object`: the object to be written

Throws
`IOException`	Any of the usual Input/Output related exceptions.
