processInput

public void processInput(java.lang.String inputName,
                java.lang.Object inputValue)

Description copied from class: Component

Processes client input specific to the Component received from the UpdateManager. Derivative implementations should take care to invoke super.processInput(). Security note: Because input to this method is likely from a remote client, it should be treated as potentially hostile. All input to this method should be carefully verified. For example, directly invoking set() method with the provided input would constitute a security hole.

Overrides:

processInput in class Component

Parameters:

inputName - the name of the input

inputValue - the value of the input

Component.processInput(java.lang.String, java.lang.Object)
