Class InstanceSupplierCodeGenerator

java.lang.Object
org.springframework.beans.factory.aot.InstanceSupplierCodeGenerator
public class InstanceSupplierCodeGenerator extends Object
Default code generator to create an InstanceSupplier, usually in the form of a BeanInstanceSupplier that retains the executable that is used to instantiate the bean. Takes care of registering the necessary hints if reflection or a JDK proxy is required.

Generated code is usually a method reference that generates the BeanInstanceSupplier, but some shortcut can be used as well such as: 

 InstanceSupplier.of(TheGeneratedClass::getMyBeanInstance);
Since:
6.0
