Class TypedStringValue

org.springframework.beans.factory.config.TypedStringValue
All Implemented Interfaces:
BeanMetadataElement
public class TypedStringValue extends Object implements BeanMetadataElement
Holder for a typed String value. Can be added to bean definitions in order to explicitly specify a target type for a String value, for example for collection elements.

This holder will just store the String value and the target type. The actual conversion will be performed by the bean factory.

1.2
