/**
|
|
* An example WrapFactory that can be used to avoid wrapping of Java types
|
|
* that can be converted to ECMA primitive values.
|
|
* So java.lang.String is mapped to ECMA string, all java.lang.Numbers are
|
|
* mapped to ECMA numbers, and java.lang.Booleans are mapped to ECMA booleans
|
|
* instead of being wrapped as objects. Additionally java.lang.Characters are
|
|
* converted to ECMA strings. Other types have the default behavior.
|
|
* <p>
|
|
* Note that calling "new java.lang.String('foo')" in JavaScript with this
|
|
* wrap factory enabled will still produce a wrapped Java object since the
|
|
* WrapFactory.wrapNewObject method is not overridden.
|
|
* <p>
|
|
* The PrimitiveWrapFactory is enabled on a Context by calling setWrapFactory
|
|
* on that context.
