Examples of org.stringtemplate.v4.STWriter

org.stringtemplate.v4.debug.AddAttributeEvent
Generic StringTemplate output writer filter. Literals and the elements of expressions are emitted via write(). Separators are emitted via writeSeparator() because they must be handled specially when wrapping lines (we don't want to wrap in between an element and it's separator).
