text	the text to append to the text results accumulated so far

EventOccurred()

virtual void iText.Kernel.Pdf.Canvas.Parser.Listener.SimpleTextExtractionStrategy.EventOccurred ( IEventData  data, EventType  type  )

inlinevirtual

Called when some event occurs during parsing a content stream.

Parameters

data	Combines the data required for processing corresponding event type.
type	Event type.

virtual String iText.Kernel.Pdf.Canvas.Parser.Listener.SimpleTextExtractionStrategy.GetResultantText ( )

inlinevirtual

Returns the result so far.

Returns

a String with the resulting text.
