Method Detail

isHttpMethodAllowedForAction

boolean isHttpMethodAllowedForAction(groovy.lang.GroovyObject controller,
                                     String httpMethod,
                                     String actionName)

Checks to see if an action is accessible via a particular http method

Parameters:

controller - The instance of the controller

httpMethod - The http request method

actionName - The action to check

Returns:

true if the action is accessible via the specified http method

isInterceptedBefore

boolean isInterceptedBefore(groovy.lang.GroovyObject controller,
                            String action)

Checks whether the specified action is intercepted for the specified controller instance

Parameters:

controller - The instance of the controller

action - The action to check

Returns:

True if it is intercepted

isInterceptedAfter

boolean isInterceptedAfter(groovy.lang.GroovyObject controller,
                           String action)

Checks whether the specified action is intercepted after for the specified controller instance

Parameters:

controller - The controller instance

action - The action to check

Returns:

True if it is intercepted

getBeforeInterceptor

groovy.lang.Closure getBeforeInterceptor(groovy.lang.GroovyObject controller)

Retrieves the before interceptor for the specified controller instance

Parameters:

controller - The controller instance

Returns:

The before interceptor as a Closure or null if non exists

getAfterInterceptor

groovy.lang.Closure getAfterInterceptor(groovy.lang.GroovyObject controller)

Retrieves the after interceptor for the specified controller instance

Parameters:

controller - The controller instance

Returns:

The after interceptor as a Closure or null if non exists

getURIs

String[] getURIs()

Gets the list of all possible URI's available in this controller.

Returns:

list of all possible URI's

mapsToURI

boolean mapsToURI(String uri)

Tests if a controller maps to a given URI.

Returns:

true if controller maps to URI

getViewByURI

String getViewByURI(String uri)

Retrieves the view name for the specified URI

Parameters:

uri - the name of URI

Returns:

the view name of null if not found

getViewByName

String getViewByName(String closureName)

Retrieves the view name for the specified closure name

Parameters:

closureName - The name of the closure

Returns:

The view for the specified closure action

getClosurePropertyName

String getClosurePropertyName(String uri)

Returns a closure property name for a specific URI or null if the URI does not map to a closure.

Parameters:

uri - the URI of the request

Returns:

the closure property name mapped to the URI or null is no closure was found

isScaffolding

boolean isScaffolding()

Returns:

True of the controller class is scaffolding

getScaffoldedClass

Class getScaffoldedClass()

Returns:

The class that is being scaffolded by this controller

getCommandObjectActions

Set getCommandObjectActions()

Returns:

A Set of names of actions with command objects presented in this controller

getCommandObjectClasses

Set getCommandObjectClasses()

Returns:

A Set of command object classes used by this controller

getFlows

Map getFlows()

Returns a map of the flows for this controller. A flow is an action that ends with the convention "Flow". The keys in the map are the flow ids which are the text before the "Flow" suffix. For example a flow called "bookFlow" would have a key of "book"

The values within the Map are Groovy closures (@see groovy.lang.Closure) which represent the flow definition

Returns:

A Map of flows for this controller

isFlowAction

boolean isFlowAction(String actionName)

Returns true if the given action name is a flow action

Parameters:

actionName - The name of the action

Returns:

True if it is a flow action
