-
public final class DefaultExpressionEngineSymbols extends java.lang.Object
A class representing the various symbols that are supported in keys recognized by
DefaultExpressionEngine
.An instance of this class is associated with each instance of
DefaultExpressionEngine
. It determines which concrete symbols are used to define elements like separators, attributes, etc. within a configuration key.Instances are created using the nested
Builder
class. They are immutable and can be shared between arbitrary components.- Since:
- 2.0
