      Specified by:
      getResolverName in interface org.mule.runtime.api.metadata.resolving.OutputTypeResolver<Object>
      Specified by:
      getResolverName in interface org.mule.runtime.api.metadata.resolving.TypeKeysResolver

    • getCategoryName

      public String getCategoryName()
      Specified by:
      getCategoryName in interface org.mule.runtime.api.metadata.resolving.NamedTypeResolver

    • getKeys

      public Set<org.mule.runtime.api.metadata.MetadataKey> getKeys(org.mule.runtime.api.metadata.MetadataContext context) throws org.mule.runtime.api.metadata.MetadataResolvingException
      Null implementation of TypeKeysResolver, used when no implementation is provided by the connector developer. Represents the absence of a custom TypeKeysResolver, returning an empty list of MetadataKey.
      Specified by:
      getKeys in interface org.mule.runtime.api.metadata.resolving.TypeKeysResolver
      Parameters:
      context - MetadataContext of the MetaData resolution
      Returns:
      Collections.emptyList()
      Throws:
      org.mule.runtime.api.metadata.MetadataResolvingException

    • getInputMetadata

      public org.mule.metadata.api.model.MetadataType getInputMetadata(org.mule.runtime.api.metadata.MetadataContext context, Object key) throws org.mule.runtime.api.metadata.MetadataResolvingException
      Null implementation of InputTypeResolver, used when no implementation is provided by the connector developer. Represents the absence of a custom InputTypeResolver, returning a VoidType instead of resolving a valid MetadataType
      Specified by:
      getInputMetadata in interface org.mule.runtime.api.metadata.resolving.InputTypeResolver<Object>
      Parameters:
      context - MetadataContext of the MetaData resolution
      key - MetadataKey of the type which's structure has to be resolved
      Returns:
      a VoidType
      Throws:
      org.mule.runtime.api.metadata.MetadataResolvingException

    • getOutputType

      public org.mule.metadata.api.model.MetadataType getOutputType(org.mule.runtime.api.metadata.MetadataContext context, Object key) throws org.mule.runtime.api.metadata.MetadataResolvingException
      Null implementation of OutputTypeResolver, used when no implementation is provided by the connector developer. Represents the absence of a custom OutputTypeResolver, returning a VoidType instead of resolving a dynamic MetadataType for the component's output.
      Specified by:
      getOutputType in interface org.mule.runtime.api.metadata.resolving.OutputTypeResolver<Object>
      Parameters:
      context - MetadataContext of the MetaData resolution

      Returns:
      a VoidType
      Throws:
      org.mule.runtime.api.metadata.MetadataResolvingException

    • getAttributesType

      public org.mule.metadata.api.model.MetadataType getAttributesType(org.mule.runtime.api.metadata.MetadataContext context, Object key) throws org.mule.runtime.api.metadata.MetadataResolvingException
      Null implementation of AttributesTypeResolver, used when no implementation is provided by the connector developer. Represents the absence of a custom AttributesTypeResolver, returning a VoidType instead of resolving a dynamic MetadataType for the component's output attributes.
      Specified by:
      getAttributesType in interface org.mule.runtime.api.metadata.resolving.AttributesTypeResolver<Object>
      Parameters:
      context - MetadataContext of the MetaData resolution
      key - MetadataKey of the type which's structure has to be resolved
