Summary:
Defined in class Component |
||
 | Name | Specifies the name for the component. The name is used as an identifier and should be unique. |
| Tag | A versatile property of every Component that can be used in any way you want |
 | ComponentCount | Indicates the number of components owned by the component. |
| Components | Lists all the components owned by this component. |
| ControlState | A flag to know the state of the control, csLoading, csDesigning |
| DataFieldValue | This property returns the value of the datafield if any. |
| NamePath | Specifies the path to uniquely identify a component, qualified by the owner when required. |
| Owner | Indicates the component that is responsible for streaming and freeing this component. |
Defined in class Persistent |
||
| NamePath | Used to serialize/unserialize. It returns the full path to identify this component. |
| Owner | Owner of the component. |

Summary: | endCache | Finish the caching process |
| | startCache | Start caching output, will be called just before start dumping content to the output. |
Defined in class Component |
||
| dumpChildrenJavascript | Dumps the javascript code for all the children |
| dumpFormItems | Dumps code just after the form tag, useful to dump hidden fields for state retrieving for non visible components |
| dumpHeaderCode | Dumps header code required |
| dumpJavascript | Dumps the javascript code needed by this component |
| hasValidDataField | Returns true if a valid data field is attached to the component |
| init | Initializes a component |
| loaded | Initializes the component after the form file has been read into memory. |
| loadedChildren | Calls childrens loaded |
| preinit | Method called before init() |
| serializeChildren | Serializes all children |
| unserializeChildren | Unserializes all children by calling unserialize for all the components |
Defined in class Persistent |
||
| serialize | Stores this object into the session. |
| unserialize | This method uses PHP reflection to iterate through published properties (the ones starting with get) and retrieve the properties stored by a previous serialize() call. |
Defined in class Object |
||
| __construct | Constructs an object and initializes its data before the object is first used. |
| className | Returns a string indicating the type of the object instance (as opposed to the type of the variable passed as an argument). |
| classParent | Returns the type of the immediate ancestor of a class. |
Method startCache (line 45)
boolean startCache( object $control, string $cachetype)
Start caching output, will be called just before start dumping content to the output.
This method should use $control and $cachetype to create a unique identifier for the cache storage and should start the caching process. If content is not cached, should return false to allow the caller know should produce the content.
If the identifier already exists, meaning the content has been already cached, then should dump out the cached content and return true.
Parameters
- object $control: Control to be cached
- string $cachetype: A prefix to specify what kind of contents are going to be cached
Info
- return - True if the content was already cached
