All Implemented Interfaces:

MappingBuilderContext.MappingResolver

public class MappingResolverImpl
extends Object
implements MappingBuilderContext.MappingResolver

The one and only implementation of MappingBuilderContext.MappingResolver. The class has been split into an interface an implementation for the sake of avoiding package dependencies. Specifically, this implementation refers to classes which should not be exposed to the model package.

                                      boolean preferUpdateMapping)

Description copied from interface: MappingBuilderContext.MappingResolver

returns a parameter assignment

Specified by:

getTargetAssignment in interface MappingBuilderContext.MappingResolver

Parameters:

mappingMethod - target mapping method

mappedElement - used for error messages

sourceType - parameter to match

targetType - return type to match

targetPropertyName - name of the target property

formattingParameters - used for formatting dates and numbers

selectionParameters - parameters used in the selection process

sourceRHS - source information

preferUpdateMapping - selection should prefer update methods when present.

Returns:

an assignment to a method parameter, which can either be:

1. MethodReference
2. TypeConversion
3. SourceRHS Assignment (empty TargetAssignment)
4. null, no assignment found
