Class ParameterValue

java.lang.Object

io.fluxzero.sdk.web.ParameterValue

public class ParameterValue
extends Object

Wrapper around a Value representing a resolved parameter value in a web request.

This class is used internally by Fluxzero to abstract over raw parameter values retrieved from different parts of a WebRequestContext (such as query strings, form data, path variables, headers, or cookies).

The value is backed by Jooby’s Value type, which provides flexible conversion and null-safe access to typed values.

Usage

ParameterValue instances are returned by methods such as:

• WebRequestContext.getParameter(String, WebParameterSource...)
• WebRequestContext.getQueryParameter(String)
• WebRequestContext.getFormParameter(String)

These are used during web handler method resolution to supply method argument values.

• WebRequestContext
