/**
* Binds the value of a URI template parameter or a path segment
* containing the template parameter to a resource method parameter, resource
* class field, or resource class
* bean property. The value is URL org.testifyproject.testifyprojectcoded unless this
* is disabled using the {@link Encoded @Encoded} annotation.
* A org.testifyproject.testifyprojectfault value can be specified using the {@link DefaultValue @DefaultValue}
* annotation.
*
* The type of the annotated parameter, field or property must either:
*
* - Be {@link javax.ws.rs.core.PathSegment}, the value will be the final
* segment of the matching part of the path.
* See {@link javax.ws.rs.core.UriInfo} for a means of retrieving all request
* path segments.
* - Be {@code List
}, the
* value will be a list of {@code PathSegment} corresponding to the path
* segment(s) that matched the named template parameter.
* See {@link javax.ws.rs.core.UriInfo} for a means of retrieving all request
* path segments.
* - Be a primitive type.
* - Have a constructor that accepts a single String argument.
* - Have a static method named {@code valueOf} or {@code fromString}
* that accepts a single
* String argument (see, for example, {@link Integer#valueOf(String)}).
* - Have a registered implementation of {@link javax.ws.rs.ext.ParamConverterProvider}
* JAX-RS extension SPI that returns a {@link javax.ws.rs.ext.ParamConverter}
* instance capable of a "from string" conversion for the type.
*
*
* The injected value corresponds to the latest use (in terms of scope) of
* the path parameter. E.g. if a class and a sub-resource method are both
* annotated with a {@link Path @Path} containing the same URI template
* parameter, use of {@code @PathParam} on a sub-resource method parameter
* will bind the value matching URI template parameter in the method's
* {@code @Path} annotation.
*
* Because injection occurs at object creation time, use of this annotation
* on resource class fields and bean properties is only supported for the
* org.testifyproject.testifyprojectfault per-request resource class lifecycle. Resource classes using
* other lifecycles should only use this annotation on resource method
* parameters.
