org.springframework.xd.module.options.PojoModuleOptionsMetadata
An implementation of {@link ModuleOptionsMetadata} that derives its information from a plain old java object:
- public setters are reported as valid options
- the type of the option is derived from the accepted type by the setter
{@link ModuleOptions} for such a POJO will work as follows:
- an instance of the class will be created reflectively and injected with user provided values,
- reported properties are computed from all the getters,
- the POJO may bear JSR303 validation annotations, which will be used to validate the interpolated options,
- if the POJO implements {@link ProfileNamesProvider}, profile names will be gathered from a reflective call to {@link ProfileNamesProvider#profilesToActivate()}
