Class Overview

Simple implementation of the TypeConverter interface that does not operate on any specific target object. This is an alternative to using a full-blown BeanWrapperImpl instance for arbitrary type conversion needs.

void	copyCustomEditorsTo(PropertyEditorRegistry target, String nestedProperty) Copy the custom editors registered in this instance to the given target registry.
void	copyDefaultEditorsTo(PropertyEditorRegistrySupport target) Copy the default editors registered in this instance to the given target registry.
PropertyEditor	findCustomEditor(Class requiredType, String propertyPath) Find a custom property editor for the given type and property.
ConversionService	getConversionService() Return the associated ConversionService, if any.
PropertyEditor	getDefaultEditor(Class requiredType) Retrieve the default editor for the given property type, if any.
Class	getPropertyType(String propertyPath) Determine the property type for the given property path.
Class	guessPropertyTypeFromEditors(String propertyName) Guess the property type of the specified property from the registered custom editors (provided that they were registered for a specific type).
boolean	hasCustomEditorForElement(Class elementType, String propertyPath) Determine whether this registry contains a custom editor for the specified array/collection element.
boolean	isSharedEditor(PropertyEditor propertyEditor) Check whether the given editor instance is a shared editor, that is, whether the given editor instance might be used concurrently.
void	overrideDefaultEditor(Class requiredType, PropertyEditor propertyEditor) Override the default editor for the specified type with the given property editor.
void	registerCustomEditor(Class requiredType, String propertyPath, PropertyEditor propertyEditor) Register the given custom property editor for the given type and property, or for all properties of the given type.
void	registerCustomEditor(Class requiredType, PropertyEditor propertyEditor) Register the given custom property editor for all properties of the given type.
void	registerDefaultEditors() Activate the default editors for this registry instance, allowing for lazily registering default editors when needed.
void	registerSharedEditor(Class requiredType, PropertyEditor propertyEditor) This method is deprecated. as of Spring 3.0, in favor of PropertyEditorRegistrars or ConversionService usage
void	setConversionService(ConversionService conversionService) Specify a Spring 3.0 ConversionService to use for converting property values, as an alternative to JavaBeans PropertyEditors.
void	useConfigValueEditors() Activate config value editors which are only intended for configuration purposes, such as `StringArrayPropertyEditor`.

Public Methods

public T convertIfNecessary (Object value, Class<T> requiredType)

Also: SpringBeans

Convert the value to the required type (if necessary from a String).

Conversions from String to any type will typically use the setAsText method of the PropertyEditor class. Note that a PropertyEditor must be registered for the given class for this to work; this is a standard JavaBeans API. A number of PropertyEditors are automatically registered.

Parameters

value	the value to convert
requiredType	the type we must convert to (or `null` if not known, for example in case of a collection element)

Returns

the new value, possibly the result of type conversion

Throws

TypeMismatchException

public T convertIfNecessary (Object value, Class<T> requiredType, MethodParameter methodParam)

Convert the value to the required type (if necessary from a String).

Conversions from String to any type will typically use the setAsText method of the PropertyEditor class. Note that a PropertyEditor must be registered for the given class for this to work; this is a standard JavaBeans API. A number of PropertyEditors are automatically registered.

Parameters

value	the value to convert
requiredType	the type we must convert to (or `null` if not known, for example in case of a collection element)
methodParam	the method parameter that is the target of the conversion (for analysis of generic types; may be `null`)

Returns

the new value, possibly the result of type conversion

Throws

TypeMismatchException
