Interface Specifying<T extends Specifying<T>>

Type Parameters:

T - Either Converting or Specifying.

All Known Subinterfaces:

Converting, Functioning

@ProviderType
public interface Specifying<T extends Specifying<T>>

This is the base interface for the Converting and Functioning interfaces and defines the common modifiers that can be applied to these.

"NotThreadSafe"

Method Summary

Modifier and Type	Method and Description
T	defaultValue(Object defVal) The default value to use when the object cannot be converted or in case of conversion from a null value.
T	keysIgnoreCase() When converting between map-like types use case-insensitive mapping of keys.
T	sourceAs(Class<?> cls) Treat the source object as the specified class.
T	sourceAsBean() Treat the source object as a JavaBean.
T	sourceAsDTO() Treat the source object as a DTO even if the source object has methods or is otherwise not recognized as a DTO.
T	targetAs(Class<?> cls) Treat the target object as the specified class.
T	targetAsBean() Treat the target object as a JavaBean.
T	targetAsDTO() Treat the target object as a DTO even if it has methods or is otherwise not recognized as a DTO.
T	view() Return a live view over the backing object that reflects any changes to the original object.

Method Detail

defaultValue

T defaultValue(Object defVal)

The default value to use when the object cannot be converted or in case of conversion from a null value.

Parameters:

defVal - The default value.

Returns:

The current Converting object so that additional calls can be chained.

keysIgnoreCase

T keysIgnoreCase()

When converting between map-like types use case-insensitive mapping of keys.

Returns:

The current Converting object so that additional calls can be chained.

sourceAs

T sourceAs(Class<?> cls)

Treat the source object as the specified class. This can be used to disambiguate a type if it implements multiple interfaces or extends multiple classes.

Parameters:

cls - The class to treat the object as.

Returns:

The current Converting object so that additional calls can be chained.

sourceAsBean

T sourceAsBean()

Treat the source object as a JavaBean. By default objects will not be treated as JavaBeans, this has to be specified using this method.

Returns:

The current Converting object so that additional calls can be chained.

sourceAsDTO

T sourceAsDTO()

Treat the source object as a DTO even if the source object has methods or is otherwise not recognized as a DTO.

Returns:

The current Converting object so that additional calls can be chained.

targetAs

T targetAs(Class<?> cls)

Treat the target object as the specified class. This can be used to disambiguate a type if it implements multiple interfaces or extends multiple classes.

Parameters:

cls - The class to treat the object as.

Returns:

The current Converting object so that additional calls can be chained.

targetAsBean

T targetAsBean()

Treat the target object as a JavaBean. By default objects will not be treated as JavaBeans, this has to be specified using this method.

Returns:

The current Converting object so that additional calls can be chained.

targetAsDTO

T targetAsDTO()

Treat the target object as a DTO even if it has methods or is otherwise not recognized as a DTO.

Returns:

The current Converting object so that additional calls can be chained.

view

T view()

Return a live view over the backing object that reflects any changes to the original object. This is only possible with conversions to Map, Collection, List and Set. The live view object will cease to be live as soon as modifications are made to it. Note that conversions to an interface or annotation will always produce a live view that cannot be modified. This modifier has no effect with conversions to other types.

Returns:

The current Converting object so that additional calls can be chained.
