public abstract class AbstractRequestVariableResolver
extends Object
implements VariableResolver

Abstract VariableResolver that resolves general request variables. The implicit objects resolved by this class are:

• param: Maps a request parameter name to a single value.
• paramValues: Maps a request parameter name to an array of values.
• header: Maps a request header name to a single value.
• headerValues: Maps a request header name to an array of values.
• cookie: Maps a cookie name to a single cookie.
• initParam: Maps a context initialization parameter name to a single value.
• requestScope: Maps request-scoped variable names to their values.
• sessionScope: Maps session-scoped variable names to their values. Corresponds to the application scope of the PortletSession.
• applicationScope: Maps application-scoped variable names to their values.
• businessContext: Maps business context property identifiers to their values.
