Interface MappingBuilderContext.MappingResolver

  • All Known Implementing Classes:
    Enclosing class:

    public static interface MappingBuilderContext.MappingResolver
    Resolves the most suitable way for mapping an element (property, iterable element etc.) from source to target. There are 2 basic types of mappings:
    • conversions
    • methods
    conversions are essentially one line mappings, such as String to Integer and Integer to Long methods come in some varieties:
    • referenced mapping methods, these are methods implemented (or referenced) by the user. Sometimes indicated with the 'uses' in the mapping annotations or part of the abstract mapper class
    • generated mapping methods (by means of MapStruct)
    • built in methods

        returns a parameter assignment
        mappingMethod - target mapping method
        description - the description source
        targetType - return type to match
        formattingParameters - used for formatting dates and numbers
        criteria - parameters criteria in the selection process
        sourceRHS - source information
        positionHint - the mirror for reporting problems
        forger - the supplier of the callback method to forge a method
        an assignment to a method parameter, which can either be:
        1. MethodReference
        2. TypeConversion
        3. SourceRHS Assignment (empty TargetAssignment)
        4. null, no assignment found
