Interface NodeResolver

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface NodeResolver
A function to resolve nodes for a specific field.

A NodeResolver.Factory is responsible for creating node resolvers for each field in an object, and provides the context necessary for a resolver to determine which node to navigate to.

Since:
4.0.0

  • Field Details

    • SKIP_FIELD

      static final NodeResolver SKIP_FIELD
      Indicates that a field should be explicitly skipped.
      Since:
      4.0.0

  • Method Details

    • resolve

      @Nullable ConfigurationNode resolve(ConfigurationNode parent)
      Given a parent node, resolve an appropriate child.

      The parent node is the node that the mapped object is being deserialized from.

      Parameters:
      parent - parent node
      Returns:
      child node, or null if the node should not be deserialized.
      Since:
      4.0.0

    • nodeKey

      static NodeResolver.Factory nodeKey()
      Creates resolvers that provide the key of the containing node for values.
      Returns:
      key-based resolver
      Since:
      4.0.0

    • keyFromSetting

      static NodeResolver.Factory keyFromSetting()
      Creates resolvers that get the node at a key defined by Setting.
      Returns:
      a factory that will extract keys from a provided annotation
      Since:
      4.0.0

    • onlyWithAnnotation

      static NodeResolver.Factory onlyWithAnnotation(Class<? extends Annotation> annotation)
      A resolver that skips any field not annotated with annotation.
      Parameters:
      annotation - annotation to require
      Returns:
      a new resolver
      Since:
      4.0.0

    • onlyWithSetting

      static NodeResolver.Factory onlyWithSetting()
      A resolver that will skip any field not annotated with Setting.
      Returns:
      new resolver restricting fields
      Since:
      4.0.0

    • nodeFromParent

      static NodeResolver.Factory nodeFromParent()
      A resolver that uses the containing node of a field.

      This can be used to combine multiple Java objects into one configuration node.

      Returns:
      new resolver using containing field value
      Since:
      4.0.0
