Class TextToMethodSignature

      org.springframework.binding.convert.support.ConversionServiceAwareConverter
          org.springframework.binding.method.TextToMethodSignature

All Implemented Interfaces:

Converter, ConversionServiceAware

public class TextToMethodSignature
extends ConversionServiceAwareConverter

Converter that takes an encoded string representation and produces a corresponding MethodSignature object.

This converter supports the following encoded forms:

• "methodName" - the name of the method to invoke, where the method is expected to have no arguments.
• "methodName(param1Type param1Name, paramNType paramNName)" - the name of the method to invoke, where the method is expected to have parameters delimited by a comma. In this example, the method has two parameters. The type is either the fully-qualified class of the argument OR a known type alias OR left out althogether. The name is the logical name of the argument, which is used during data binding to retrieve the argument value (typically an expression).
