Method Detail

close

public void close()
           throws java.io.IOException,
                  CardTerminalException

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

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException - If an I/O error has occurred.

CardTerminalException - Thrown when the smart card has been removed.

flush

public void flush()
           throws java.io.IOException,
                  CardTerminalException

Flushes this CardFileOutputStream and forces any buffered output bytes to be written out.

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.OutputStream

Throws:

CardTerminalException - Thrown when the smart card has been removed.

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

write

public void write(int b)
           throws java.io.IOException,
                  CardTerminalException

Write a byte of data.

Specified by:

write in class java.io.OutputStream

Parameters:

b - The byte to be written

Throws:

java.io.IOException - Thrown if an I/O error has occured.

CardTerminalException - Thrown when the smart card has been removed.

write

public void write(byte[] b)
           throws java.io.IOException,
                  CardTerminalException

Write an array of bytes.

Overrides:

write in class java.io.OutputStream

Parameters:

b - The data to be written

Throws:

java.io.IOException - Thrown if an I/O error has occured.

CardTerminalException - Thrown when the smart card has been removed.

write

public void write(byte[] b,
                  int offset,
                  int length)
           throws java.io.IOException,
                  CardTerminalException

Write a slice of a byte array.

Overrides:

write in class java.io.OutputStream

Parameters:

b - The data to be written

offset - The start offset in the data (not in the file!)

length - The number of bytes that are written

Throws:

java.io.IOException - Thrown if an I/O error has occured.
