Interface TypeHandler<T,S>

Type Parameters:

T - target type for converting

S - type returned by javascript execution

All Known Implementing Classes:

JQueryTypeHandler

public interface TypeHandler<T,S>

This class is responsible for converting the result of a javascript function into another type.

If your js-interface defines a return type, which is not supported by JavascriptExecutor, vani tries to find an TypeHandler, which is able to convert to the declared return type.

For example, the jquery interface returns JQueryElement. Therefore there is a implementation for converting to the required type.

Declaration and Registration

You only have to implements this interface and annotated the class with JsTypeHandler. That's all.
All type handlers will be instantiated and registered during spring context startup.
