Components (CFCs)


  • ComponentCacheClear() flush the component path cache
  • ComponentCacheList() list elements in the component path cache
  • CreateObject() The CreateObject function takes different arguments depending on the value of the first argument:
  • GetComponentMetaData() Gets metadata (such as the functions and implemented interfaces of a component) for a CFC or Interface.
  • GetComponentStaticScope() returns the static scope of a specific component, of course access rules apply.
  • GetMetadata() Returns back meta information depending on the object passed in
  • IsClosure() checks if given Object is a closure or not.
  • IsCustomFunction() Determines whether a name represents a custom function
  • IsInstanceOf() Determines whether an object is an instance of a Lucee interface or component, or of a Java class.
  • IsValid() Tests whether a value meets a validation or data type rule.


  • Access Modifiers for variables public and private scope for component variables
  • Implicit Conversion Functions Following up with Magic Functions - Implicit Component Getters / Setters , there's one more gem. Again, this has been around since Lucee 2. We're going to make a new, yet similar example. This time, we're going to create an address object: address.cfc ```lucee #getStreet1()# #getCity()#, #getState()# #getPostalCode()# ``` *index
  • Magic Functions - Implicit Component Getters / Setters ### Enabling Magic Functions via Admin ### You can enable magic functions in the web / server context by going to: http://{your host name}/lucee/admin/web.cfm?action=resources.component - Local web context http://{your host name}/lucee/admin/server.cfm?action=resources.component - Global web context Enable the setting: `Implicit notation` **The Code** Once, you've checked and enabled it, we're ready to start with some code
  • Static scope in components Static scope in components is needed to create an instance of cfc and call its method
  • Static support for components Lucee 5 supports static variables and functions inside components


  • <cfargument> Allows subtag data to be saved with the base tag. Applies only to custom tags.
  • <cfcomponent> Creates and defines a component object
  • <cffunction> Defines a function that can accept arguments and return a value.
  • <cfinterface> Defines an interface that consists of a set of signatures for functions.
  • <cfinvoke> Invokes component methods from within a page or component. You use this tag to reference a WSDL file and consume a web service from within a block of CFML code.
  • <cfinvokeargument> Argument for the Invoke Tag
  • <cfobject> Lets you call methods in COM, CORBA, and JAVA objects.
  • <cfreturn> Returns result values from a component method. Contains an expression returned as result of the function.
  • <cfstatic> defines a static constructor within components
