      org.springframework.beans.support.ArgumentConvertingMethodInvoker

Direct Known Subclasses:: MethodInvokingFactoryBean, MethodInvokingJobDetailFactoryBean, MethodInvokingRunnable

public class ArgumentConvertingMethodInvoker
extends MethodInvoker
extends MethodInvoker

Subclass of MethodInvoker that tries to convert the given arguments for the actual target method via BeanWrapperImpl.

Supports flexible argument conversions, in particular for invoking a specific overloaded method.

Constructor Detail

ArgumentConvertingMethodInvoker

public ArgumentConvertingMethodInvoker()

Method Detail

setTypeConverter

public void setTypeConverter(TypeConverter typeConverter)

Set a TypeConverter to use for argument type conversion.

Default is a SimpleTypeConverter. Can be overridden with any TypeConverter implementation, typically a pre-configured SimpleTypeConverter or a BeanWrapperImpl instance.

See Also:: SimpleTypeConverter, BeanWrapperImpl

getTypeConverter

public TypeConverter getTypeConverter()

Return the TypeConverter used for argument type conversion.

Can be cast to PropertyEditorRegistry if direct access to the underlying PropertyEditors is desired (provided that the present TypeConverter actually implements the PropertyEditorRegistry interface).

getDefaultTypeConverter

protected TypeConverter getDefaultTypeConverter()

Obtain the default TypeConverter for this method invoker.

Called if no explicit TypeConverter has been specified. The default implementation builds a SimpleTypeConverter. Can be overridden in subclasses.

registerCustomEditor

public void registerCustomEditor(Class requiredType,
                                 PropertyEditor propertyEditor)

Typically used in conjunction with the default SimpleTypeConverter; will work with any TypeConverter that implements the PropertyEditorRegistry interface as well.

Parameters:: requiredType - type of the property; propertyEditor - editor to register
See Also:: setTypeConverter(org.springframework.beans.TypeConverter), PropertyEditorRegistry.registerCustomEditor(java.lang.Class, java.beans.PropertyEditor)

findMatchingMethod

protected Method findMatchingMethod()

This implementation looks for a method with matching parameter types: that is, where each argument value is assignable to the corresponding parameter type.

Overrides:: findMatchingMethod in class MethodInvoker

Returns:: a matching method, or null if none
See Also:: MethodInvoker.getTargetClass(), MethodInvoker.getTargetMethod(), MethodInvoker.getArguments()
