    • newInstance

      public ParametersDefinitionProperty newInstance(org.kohsuke.stapler.StaplerRequest req, net.sf.json.JSONObject formData) throws Descriptor.FormException
      Description copied from class: Descriptor
      Creates a configured instance from the submitted form.

      Hudson only invokes this method when the user wants an instance of T. So there's no need to check that in the implementation.

      The default implementation of this method uses Descriptor.bindJSON(org.kohsuke.stapler.StaplerRequest, java.lang.Class<T>, net.sf.json.JSONObject) which performs the databinding on the constructor of Descriptor.clazz.

      For some types of Describable, such as ListViewColumn, this method can be invoked with null request object for historical reason. Such design is considered broken, but due to the compatibility reasons we cannot fix it. Because of this, the default implementation gracefully handles null request, but the contract of the method still is "request is always non-null." Extension points that need to define the "default instance" semantics should define a descriptor subtype and add the no-arg newInstance method.

      Overrides:
      newInstance in class OptionalJobProperty.OptionalJobPropertyDescriptor
      Parameters:
      req - Always non-null (see note above.) This object includes represents the entire submission.
      formData - The JSON object that captures the configuration data for this Descriptor. See the developer documentation. Always non-null.
      Returns:
      null to avoid setting an instance of JobProperty to the target project (or just use OptionalJobProperty)
      Throws:
      Descriptor.FormException - Signals a problem in the submitted form.

    • isApplicable

      public boolean isApplicable(Class<? extends Job> jobType)
      Description copied from class: JobPropertyDescriptor
      Returns true if this JobProperty type is applicable to the given job type.

      The default implementation of this method checks if the given job type is assignable to J of JobProperty<J>, but subtypes can extend this to change this behavior.

      Overrides:
      isApplicable in class JobPropertyDescriptor
      Returns:
      true to indicate applicable, in which case the property will be displayed in the configuration screen of this job.

    • getDisplayName

      @NonNull public String getDisplayName()
      Description copied from class: Descriptor
      Human readable name of this kind of configurable object. Should be overridden for most descriptors, if the display name is visible somehow. As a fallback it uses Class.getSimpleName() on Descriptor.clazz, so for example MyThing from some.pkg.MyThing.DescriptorImpl. Historically some implementations returned null as a way of hiding the descriptor from the UI, but this is generally managed by an explicit method such as isEnabled or isApplicable.
      Overrides:
      getDisplayName in class Descriptor<JobProperty<?>>
