Methods Summary

Methods
Type Params	Return Type	Name and description

	`public byte`	`byteValue()` Returns `0` because this wrapper is not numeric.
	`public char`	`charAt(int index)` Returns the placeholder character `'0'` because no character data is available.
	`public char`	`charValue()` Returns `0` because this wrapper is not backed by character data.

	`public short`	`shortValue()` Returns `0` because this wrapper is not numeric.
	`public String`	`stringValue()` Returns the string form using the value's configured decoding policy. Returns: the string representation
	`public String`	`stringValueEncoded()` Returns the fully decoded string form. Returns: the decoded string representation
	`public CharSequence`	`subSequence(int start, int end)` Returns an empty character sequence because this wrapper has no character backing.
`<T extends Enum>`	`public T`	`toEnum(Class<T> cls)` Returns the cached enum instance stored in this wrapper.
	`public String`	`toString()` Returns the token name for this wrapper.
	`public Object`	`toValue()` Materializes this token as a regular Java value. Returns: the hydrated value
