Member Function Documentation

- (id) initWithFallback: (id)  prevFilter terminal: (id)  terminal

Designated initializer. Initializes the parameter count and state variable. Reimplemented from CharacterLineFilter.

- (id) processCharacter: (unichar)  character

Process a character from the host. In a new EscapeLineFilter (state == 0), this will be the first character after the escape; characters will change the state of the filter and be interpreted in light of the accumulated state. Parameters: [in]  character  The character from the host. Return values: CharacterLineFilter  The handler for the next character from the host. Reimplemented from CharacterLineFilter.
