    • validateMirrorSet

    • getAnnotationType

      Class<? extends Annotation> getAnnotationType()
      Get the type of the mapped annotation.
      返回:
      the annotation type

    • getAliasMapping

      int getAliasMapping(int attributeIndex)
      Get the related index of an alias mapped attribute, or -1 if there is no mapping. The resulting value is the index of the attribute on the root annotation that can be invoked in order to obtain the actual value.
      参数:
      attributeIndex - the attribute index of the source attribute
      返回:
      the mapped attribute index or -1

    • getConventionMapping

      int getConventionMapping(int attributeIndex)
      Get the related index of a convention mapped attribute, or -1 if there is no mapping. The resulting value is the index of the attribute on the root annotation that can be invoked in order to obtain the actual value.
      参数:
      attributeIndex - the attribute index of the source attribute
      返回:
      the mapped attribute index or -1

    • getMappedAnnotationValue

      @Nullable Object getMappedAnnotationValue(int attributeIndex, boolean metaAnnotationsOnly)
      Get a mapped attribute value from the most suitable meta-annotation.

      The resulting value is obtained from the closest meta-annotation, taking into consideration both convention and alias based mapping rules. For root mappings, this method will always return null.

      参数:
      attributeIndex - the attribute index of the source attribute
      metaAnnotationsOnly - if only meta annotations should be considered. If this parameter is false then aliases within the annotation will also be considered.
      返回:
      the mapped annotation value, or null

    • isEquivalentToDefaultValue

      boolean isEquivalentToDefaultValue(int attributeIndex, Object value, ValueExtractor valueExtractor)
      Determine if the specified value is equivalent to the default value of the attribute at the given index.
      参数:
      attributeIndex - the attribute index of the source attribute
      value - the value to check
      valueExtractor - the value extractor used to extract values from any nested annotations
      返回:
      true if the value is equivalent to the default value
