com.blackrook.rookscript.resolvers.variable.DefaultVariableResolver

All Implemented Interfaces:

ScriptVariableResolver

public class DefaultVariableResolver
extends AbstractVariableResolver

A single, scoped open variable set in which values can be set. All variable names are CASE-INSENSITIVE. The internals are written so that the storage uses few memory allocations/deletions. None of the variables are read-only. This implementation is thread-safe.
