org.aspectj.org.eclipse.jdt.core.dom.SwitchCase
Switch case AST node type. A switch case is a special kind of node used only
in switch statements. It is a
Statement
in name only.
SwitchCase: case Expression : default : Switch case allows multiple expressions and '->' as part of Java 12 preview feature (JEP 325) case [ Expression { , Expression } ] { : | ->} default { : | ->}
