onRawText

public void onRawText(java.lang.String text,

Specified by:

onRawText in interface Listener

Parameters:

text - the text to inject

syntax - the syntax in which the text is written. This is useful so that listener implementations can decide whether they can handle direct inject for that syntax

See Also:

Listener.onRawText(String, Syntax)
