public interface BeanMapper

This is the interface used to convert from one Java bean to another compatible bean (e.g. from a JPA entity to a corresponding transfer-object).

Method Detail

map

<T> T map(Object source,
          Class<T> targetClass)

Recursively converts the given source Object to the given target Class.

Type Parameters:

T - is the generic type to convert to.

Parameters:

source - is the object to convert.

targetClass - is the Class reflecting the type to convert to.

Returns:

the converted object. Will be null if source is null.

mapTypesafe

<API,S extends API,T extends API> T mapTypesafe(Class<API> apiClass,
                                                            S source,
                                                            Class<T> targetClass)

A type-safe variant of map(Object, Class) to prevent accidental abuse (e.g. mapping of apples to bananas).

Type Parameters:

API - is a common super-type (interface) of source and targetType.

S - is the generic type of source.

T - is the generic type to convert to (target).

Parameters:

apiClass - is the Class reflecting the <API>.

source - is the object to convert.

targetClass - is the Class reflecting the type to convert to.

Returns:

the converted object. Will be null if source is null.

mapList

<T> List<T> mapList(List<?> source,
                    Class<T> targetClass)

Creates a new List with the mapped bean for each entry of the given List. Uses false for suppressNullValues (see mapList(List, Class, boolean)).

Type Parameters:

T - is the generic type to convert the List entries to.

Parameters:

source - is the List with the source objects.

targetClass - is the Class reflecting the type to convert each List entry to.

Returns:

the List with the converted objects. Will be empty is source is empty or null.

mapList

<T> List<T> mapList(List<?> source,
                    Class<T> targetClass,
                    boolean suppressNullValues)

Creates a new List with the mapped bean for each entry of the given List.

Type Parameters:

T - is the generic type to convert the List entries to.

Parameters:

source - is the List with the source objects.

targetClass - is the Class reflecting the type to convert each List entry to.

suppressNullValues - true if null values shall be suppressed/omitted in the resulting List, false otherwise.

Returns:

the List with the converted objects. Will be empty is source is empty or null.

Since:

1.3.0

mapSet

<T> Set<T> mapSet(Set<?> source,
                  Class<T> targetClass)

Creates a new Set with the mapped bean for each entry of the given Set. Uses false for suppressNullValues (see mapSet(Set, Class, boolean)).

Type Parameters:

T - is the generic type to convert the Set entries to.

Parameters:

source - is the Set with the source objects.

targetClass - is the Class reflecting the type to convert each Set entry to.

Returns:

the Set with the converted objects. Will be empty is source is empty or null.

mapSet

<T> Set<T> mapSet(Set<?> source,
                  Class<T> targetClass,
                  boolean suppressNullValues)

Creates a new Set with the mapped bean for each entry of the given Set.

Type Parameters:

T - is the generic type to convert the Set entries to.

Parameters:

source - is the Set with the source objects.

targetClass - is the Class reflecting the type to convert each Set entry to.

suppressNullValues - true if null values shall be suppressed/omitted in the resulting Set, false otherwise.

Returns:

the Set with the converted objects. Will be empty is source is empty or null.
