A representation of the model object 'Literal Expression'.
@see com.puppetlabs.geppetto.pp.PPPackage#getLiteralExpression()
@model abstract="true"
@generated
A very simple hardcoded implementation of the Expression interface that represents a string literal. It is used with CompositeStringExpression when representing a template expression which is made up of pieces - some being real expressions to be handled by an EL implementation like Spel, and some being just textual elements.
