Class PrettyPrinter

java.lang.Object

com.google.gwt.inject.rebind.util.PrettyPrinter

public final class PrettyPrinter
extends Object

Pretty-printer that formats internal types for human consumption in error messages.

format(String, Object...) acts like String.format(java.lang.String, java.lang.Object...), except that it detects and pretty-prints the following argument types:

• Class: formatted as "org.example.Class$SubClass"
• Key: formatted as "@org.example.Annotation org.example.Class$SubClass"
• List: formatted as a dependency path preceded by a newline. If the path begins at Dependency.GINJECTOR, that key is hidden, and the context of the outgoing dependency is given as the context of the first key in the displayed path.

All other arguments are passed unchanged to String.format(java.lang.String, java.lang.Object...).
