Examples of com.google.gwt.dev.javac.CompilationUnit

com.google.gwt.dev.javac.CompilationUnit
Encapsulates the state of a single active compilation unit in a particular module. State is accumulated throughout the life cycle of the containing module and may be invalidated at certain times and recomputed.
