Method Detail

enhanceCommandObject

static void enhanceCommandObject(org.springframework.context.ApplicationContext ctx, java.lang.Class commandObjectClass)
Enhances a command object with new capabilities such as validation and constraints handling
Parameters:
commandObjectClass - The command object class

enhanceTagLibMetaClass

static void enhanceTagLibMetaClass(GrailsTagLibClass taglib, TagLibraryLookup gspTagLibraryLookup)

getCommandObjectBindingSource

static DataBindingSource getCommandObjectBindingSource(java.lang.Class commandObjectClass, DataBindingSource params)

isCommandObjectAction

static boolean isCommandObjectAction(groovy.lang.Closure callable)
Checks whether the given action is a command object action
Parameters:
callable - The action to check
Returns:
true if it is a command object action

prepareCommandObjectBindingAction

static groovy.lang.Closure prepareCommandObjectBindingAction(groovy.lang.Closure action, groovy.lang.Closure originalAction, java.lang.String actionName, java.lang.Object controller, org.springframework.context.ApplicationContext ctx)
Prepares a command object binding action for usage
Parameters:
action - The binding action
originalAction - The original action to be replacec
actionName - The action name
controller - The controller
Returns:
The new binding action

prepareCommandObjectBindingAction

@java.lang.SuppressWarnings("rawtypes")
static void prepareCommandObjectBindingAction(java.lang.reflect.Method action, java.lang.Class[] commandObjectClasses, org.springframework.context.ApplicationContext ctx)
Prepares a command object binding action for usage
Parameters:
action - The binding action

registerCommonWebProperties

static java.lang.Object registerCommonWebProperties(groovy.lang.MetaClass mc, GrailsApplication application)
This creates the difference dynamic methods and properties on the controllers. Most methods are implemented by looking up the current request from the RequestContextHolder (RCH)

registerMethodMissingForTags

@groovy.transform.CompileStatic
static java.lang.Object registerMethodMissingForTags(groovy.lang.MetaClass metaClass, TagLibraryLookup gspTagLibraryLookup, java.lang.String namespace, java.lang.String name)

registerMethodMissingForTags

static java.lang.Object registerMethodMissingForTags(groovy.lang.MetaClass mc, org.springframework.context.ApplicationContext ctx, GrailsTagLibClass tagLibraryClass, java.lang.String name)

registerPropertyMissingForTag

static void registerPropertyMissingForTag(groovy.lang.MetaClass mc, java.lang.String name, java.lang.Object result)

registerStreamCharBufferMetaClass

static java.lang.Object registerStreamCharBufferMetaClass()
