ObjectInput extends the DataInput interface to include the reading of objects. DataInput includes methods for the input of primitive types, ObjectInput extends that interface to include objects, arrays, and Strings.

Since:

1.1

Method Summary
int	available() Returns the number of bytes that can be read without blocking.
void	close() Closes the input stream.
int	read() Reads a byte of data.
int	read(byte[] b) Reads into an array of bytes.
int	read(byte[] b, int off, int len) Reads into an array of bytes.
Object	readObject() Read and return an object.
long	skip(long n) Skips n bytes of input.

Method Detail

readObject

Object readObject	()
throws	ClassNotFoundException, IOException

Read and return an object. The class that implements this interface defines where the object is "read" from.

Returns:

the object read from the stream

Throws:

ClassNotFoundException - If the class of a serialized object cannot be found.

IOException - If any of the usual Input/Output related exceptions occur.

read

int read	()
throws	IOException

Reads a byte of data. This method will block if no input is available.

Returns:

the byte read, or -1 if the end of the stream is reached.

Throws:

IOException - If an I/O error has occurred.

read

int read	(byte[] b)
throws	IOException

Reads into an array of bytes. This method will block until some input is available.

Parameters:

b - the buffer into which the data is read

Returns:

the actual number of bytes read, -1 is returned when the end of the stream is reached.

Throws:

IOException - If an I/O error has occurred.

read

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

Reads into an array of bytes. This method will block until some input is available.

Parameters:

b - the buffer into which the data is read

off - the start offset of the data

len - the maximum number of bytes read

Returns:

the actual number of bytes read, -1 is returned when the end of the stream is reached.

Throws:

IOException - If an I/O error has occurred.

skip

long skip	(long n)
throws	IOException

Skips n bytes of input.

Parameters:

n - the number of bytes to be skipped

Returns:

the actual number of bytes skipped.

Throws:

IOException - If an I/O error has occurred.

available

int available	()
throws	IOException

Returns the number of bytes that can be read without blocking.

Returns:

the number of available bytes.

Throws:

IOException - If an I/O error has occurred.

void close	()
throws	IOException

Closes the input stream. Must be called to release any resources associated with the stream.

Specified by:

close in interface AutoCloseable

Throws:

IOException - If an I/O error has occurred.
