Class ControlSymbol

java.lang.Object

org.ek9lang.compiler.symbols.Symbol

org.ek9lang.compiler.symbols.ScopedSymbol

org.ek9lang.compiler.symbols.ControlSymbol

All Implemented Interfaces:

Serializable, IScope, IScopedSymbol, ISymbol, ITokenReference

Direct Known Subclasses:

SwitchSymbol, TrySymbol

public class ControlSymbol
extends ScopedSymbol

EK9 switch/try control type symbol - this can effectively return a value if it is configured with returning part. When generating output we need this to create its own block so variables inside are hidden from later scopes. So as we have a returning part (optional) we need a scope to put it in (i.e. this scope) this then means that when we finally come to generate the output - this symbol will be able to supply the outer variable to set the result to.
