Class BeanBuilder

java.lang.Object

com.fasterxml.jackson.module.mrbean.BeanBuilder

public class BeanBuilder
extends Object

Heavy lifter of mr Bean package: class that keeps track of logical POJO properties, and figures out how to create an implementation class.

Constructor Detail

BeanBuilder

public BeanBuilder(com.fasterxml.jackson.databind.JavaType type,
                   com.fasterxml.jackson.databind.introspect.AnnotatedClass ac,
                   com.fasterxml.jackson.databind.type.TypeFactory tf)

Method Detail

construct

public static BeanBuilder construct(com.fasterxml.jackson.databind.cfg.MapperConfig<?> config,
                                    com.fasterxml.jackson.databind.JavaType type,
                                    com.fasterxml.jackson.databind.introspect.AnnotatedClass ac)

implement

public BeanBuilder implement(boolean failOnUnrecognized)

Parameters:

failOnUnrecognized - If true, and an unrecognized (non-getter, non-setter) method is encountered, will throw IllegalArgumentException; if false, will implement bogus method that will throw UnsupportedOperationException if called.

build

public byte[] build(String className)

Method that generates byte code for class that implements abstract types requested so far.

Parameters:

className - Fully-qualified name of the class to generate

Returns:

Byte code Class instance built by this builder

hasConcreteOverride

protected boolean hasConcreteOverride(Method m0,
                                      com.fasterxml.jackson.databind.JavaType implementedType)

Helper method used to detect if an abstract method found in a base class may actually be implemented in a (more) concrete sub-class.
