Method Summary

boolean	accept(String extensionType, String extensionName, Map<String,Object> context) Checks if all the filters pass, if one filter doesn't pass the method UIExtension.onDeny will be called
protected boolean	accept(UIExtension extension, Map<String,Object> context, boolean checkOnly)
org.exoplatform.webui.core.UIComponent	addUIExtension(String extensionType, String extensionName, Map<String,Object> context, org.exoplatform.webui.core.UIContainer parent) First check if the given extension exists, if so it checks if the extension can be added according (all filters that are mandatory) to the given context, if so it adds the extension to the parent and returns the extension otherwise it returns null

Method Detail

accept

public boolean accept(String extensionType,
                      String extensionName,
                      Map<String,Object> context)

Checks if all the filters pass, if one filter doesn't pass the method UIExtension.onDeny will be called

Specified by:

accept in interface UIExtensionManager

Parameters:

extensionType - the type of the extension, usually it is the FQN of the component that displays the extension

extensionName - the name of the extension to add

context - the context to check

Returns:

true if all the filter could pass, false otherwise

addUIExtension

public org.exoplatform.webui.core.UIComponent addUIExtension(String extensionType,
                                                             String extensionName,
                                                             Map<String,Object> context,

                                                      throws Exception

First check if the given extension exists, if so it checks if the extension can be added according (all filters that are mandatory) to the given context, if so it adds the extension to the parent and returns the extension otherwise it returns null

Specified by:

addUIExtension in interface UIExtensionManager

Parameters:

extensionType - the type of the extension, usually it is the FQN of the component that displays the extension

extensionName - the name of the extension to add

context - the context to check in order to know if the extension can be added

parent - the parent component to which the extension must be added

Returns:

the component related to the extension if it can be added, null otherwise

Throws:

Exception - if an error occurs

addUIExtension

public org.exoplatform.webui.core.UIComponent addUIExtension(UIExtension extension,
