Method Detail

read

public int read(byte[] array,
                int off,
                int len)
         throws java.io.IOException

Read the specified number of bytes into an array.

Overrides:

read in class java.io.InputStream

Parameters:

array - the byte array to read into

off - the offset to start reading bytes into

len - the number of bytes to read

Returns:

the number of bytes read or -1 if the end of the stream has been reached

Throws:

java.io.IOException - if an I/O error occurs

read

public int read(byte[] b)
         throws java.io.IOException

Read the specified number of bytes into an array.

Overrides:

read in class java.io.InputStream

Parameters:

b - the byte array to read into

Returns:

the number of bytes read or -1 if the end of the stream has been reached

Throws:

java.io.IOException - if an I/O error occurs

read

public int read()
         throws java.io.IOException

Read a single byte.

Specified by:

read in class java.io.InputStream

Returns:

either the byte read or -1 if the end of the stream has been reached

Throws:

java.io.IOException - if an I/O error occurs

close

public void close()
           throws java.io.IOException

Close the stream. This method will cause the underlying Reader to be closed.

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class java.io.InputStream

Throws:

java.io.IOException - if an I/O error occurs
