Constructor Detail

PropertyTypeDescriptor

public PropertyTypeDescriptor(MethodParameter methodParameter,
                              PropertyDescriptor propertyDescriptor)

Create a new type descriptor for the given bean property.

Parameters:

methodParameter - the target method parameter

propertyDescriptor - the corresponding JavaBean PropertyDescriptor

Method Detail

forNestedType

public static PropertyTypeDescriptor forNestedType(MethodParameter methodParameter,
                                                   PropertyDescriptor propertyDescriptor)

Create a new type descriptor for a nested type declared on an array, collection, or map-based property. Use this factory method when you've resolved a nested source object such as a collection element or map value and wish to have it converted. Builds in protection for increasing the nesting level of the provided MethodParameter if the nestedType is itself a collection.

Parameters:

methodParameter - the method parameter

Returns:

the property descriptor

forNestedType

public static PropertyTypeDescriptor forNestedType(Class<?> nestedType,
                                                   MethodParameter methodParameter,
                                                   PropertyDescriptor propertyDescriptor)

Create a new type descriptor for a nested type declared on an array, collection, or map-based property. Use this factory method when you've resolved a nested source object such as a collection element or map value and wish to have it converted. Builds in protection for increasing the nesting level of the provided MethodParameter if the nestedType is itself a collection.

Parameters:

nestedType - the nested type

methodParameter - the method parameter

Returns:

the property descriptor

getPropertyDescriptor

public PropertyDescriptor getPropertyDescriptor()

Return the underlying PropertyDescriptor.

resolveAnnotations

protected Annotation[] resolveAnnotations()

Overrides:

resolveAnnotations in class TypeDescriptor

newNestedTypeDescriptor

protected TypeDescriptor newNestedTypeDescriptor(Class<?> nestedType,
                                                 MethodParameter nested)

Overrides:

newNestedTypeDescriptor in class TypeDescriptor
