Class AcceptableNestingDepthOrError

java.lang.Object

org.ek9lang.compiler.phase5.AcceptableNestingDepthOrError

All Implemented Interfaces:

Consumer<org.antlr.v4.runtime.tree.ParseTree>

class AcceptableNestingDepthOrError
extends Object
implements Consumer<org.antlr.v4.runtime.tree.ParseTree>

Checks nesting depth at function/method/operator exit and emits error if too deep. Deep nesting makes code hard to read and maintain - this enforces a reasonable limit. The limit applies to control structures: if, while, for, switch, try/catch/finally.
