Interface Application

All Superinterfaces:

javacard.framework.Shareable

public interface Application

extends javacard.framework.Shareable

This defines the interface that represents an applet method accessible through the OPEN to the application's associated Security Domain. This interface must be implemented by the Applet class that will use the additional functionality allowing a Security Domain to pass data to the applet.

Method Summary

void	processData(byte[] baBuffer, short sOffset, short sLength) This method processes application specific data received from another entity on the card.

Method Detail

processData

public void processData(byte[] baBuffer,
                        short sOffset,
                        short sLength)

This method processes application specific data received from another entity on the card. If this other entity is the Application's associated Security Domain, this data is the APDU buffer.

Notes:

• During the invocation the Java Card VM performs a context switch.
• The application is responsible for managing the atomicity of its own data.
• As this method can be invoked by a Security Domain immaterial of the Application Life Cycle State, it is the responsibility of the applet to ensure that its current Life Cycle State is valid for this operation.
• As the applet is not the selected application, it should not use the CLEAR_ON_DESELECT when creating transient arrays.

Parameters:

baBuffer - the source byte array containing the data expected by the applet. This buffer must be global.

sOffset - starting offset of data within source byte array.

sLength - length of data.
