Methods

Modifier and Type	Method and Description
void	addExtensibilityDirectives(java.util.Map freeMarkerModel, org.springframework.extensions.surf.extensibility.ExtensibilityModel extModel) Adds the <@markup> directive to the container which allows FreeMarker templates to be extended.

void	setExtensibilityModuleHandler(org.springframework.extensions.surf.extensibility.WebScriptExtensibilityModuleHandler extensibilityModuleHandler) Sets the WebScriptExtensibilityModuleHandler for this Container.
void	setFileBeingProcessed(java.lang.String file) Sets the path of the file currently being processed in the model by the current thread.

Method Detail

executeScript

public void executeScript(org.springframework.extensions.webscripts.WebScriptRequest scriptReq,
                 org.springframework.extensions.webscripts.WebScriptResponse scriptRes,
                 org.springframework.extensions.webscripts.Authenticator auth)
                   throws java.io.IOException

Opens a new ExtensibilityModel, defers execution to the extended RepositoryContainer and then closes the ExtensibilityModel.

Specified by:

executeScript in interface org.springframework.extensions.webscripts.RuntimeContainer

Overrides:

executeScript in class RepositoryContainer

Throws:

java.io.IOException

setExtensibilityModuleHandler

public void setExtensibilityModuleHandler(org.springframework.extensions.surf.extensibility.WebScriptExtensibilityModuleHandler extensibilityModuleHandler)

Sets the WebScriptExtensibilityModuleHandler for this Container.

Parameters:

extensibilityModuleHandler -

openExtensibilityModel

public org.springframework.extensions.surf.extensibility.ExtensibilityModel openExtensibilityModel()

Creates a new ExtensibilityModel and sets it on the current thread

Specified by:

openExtensibilityModel in interface org.springframework.extensions.surf.extensibility.HandlesExtensibility

closeExtensibilityModel

public void closeExtensibilityModel(org.springframework.extensions.surf.extensibility.ExtensibilityModel model,
                           java.io.Writer out)

Flushes the ExtensibilityModel provided and sets its parent as the current ExtensibilityModel for the current thread.

Specified by:

closeExtensibilityModel in interface org.springframework.extensions.surf.extensibility.HandlesExtensibility

getCurrentExtensibilityModel

public org.springframework.extensions.surf.extensibility.ExtensibilityModel getCurrentExtensibilityModel()

Returns the ExtensibilityModel for the current thread.

Specified by:

getCurrentExtensibilityModel in interface org.springframework.extensions.surf.extensibility.HandlesExtensibility

updateExtendingModuleDependencies

public void updateExtendingModuleDependencies(java.lang.String pathBeingProcessed,
                                     java.util.Map model)

This method is implemented to perform no action as it is not necessary for a standalone WebScript container to add dependencies for processing.

Specified by:

updateExtendingModuleDependencies in interface org.springframework.extensions.surf.extensibility.HandlesExtensibility

getCachedExtendedBundle

public java.util.ResourceBundle getCachedExtendedBundle(java.lang.String webScriptId)

Checks the cache to see if it has cached an extended bundle (that is a basic ResourceBundle that has had extension modules applied to it. Extended bundles can only be safely cached once per request as the modules applied can vary for each request.

Specified by:

getCachedExtendedBundle in interface org.springframework.extensions.surf.extensibility.HandlesExtensibility

Parameters:

webScriptId - The id of the WebScript to retrieve the extended bundle for.

Returns:

A cached bundle or null if the bundle has not previously been cached.

addExtensionBundleToCache

public void addExtensionBundleToCache(java.lang.String webScriptId,
                             org.springframework.extensions.webscripts.WebScriptPropertyResourceBundle extensionBundle)

Adds a new extended bundle to the cache. An extended bundle is a WebScript ResourceBundle that has had ResourceBundle instances merged into it from extension modules that have been applied. These can only be cached for the lifetime of the request as different modules may be applied to the same WebScript for different requests.

Specified by:

addExtensionBundleToCache in interface org.springframework.extensions.surf.extensibility.HandlesExtensibility

Parameters:

webScriptId - The id of the WebScript to cache the extended bundle against.

extensionBUndle - The extended bundle to cache.

getFileBeingProcessed

public java.lang.String getFileBeingProcessed()

Returns the path of the file currently being processed in the model by the current thread. This information is primarily provided for the purposes of generating debug information.

Specified by:

getFileBeingProcessed in interface org.springframework.extensions.surf.extensibility.HandlesExtensibility

Returns:

The path of the file currently being processed.

setFileBeingProcessed

public void setFileBeingProcessed(java.lang.String file)

Sets the path of the file currently being processed in the model by the current thread. This information should be collected to assist with providing debug information.

Specified by:

setFileBeingProcessed in interface org.springframework.extensions.surf.extensibility.HandlesExtensibility

Parameters:

file - The path of the file currently being processed.

getExtendingModuleFiles

public java.util.List getExtendingModuleFiles(java.lang.String pathBeingProcessed)

Retrieves an files for the evaluated modules that are extending the WebScript files being processed.

Specified by:

getExtendingModuleFiles in interface org.springframework.extensions.surf.extensibility.HandlesExtensibility

getEvaluatedModules

public java.util.List getEvaluatedModules()

Retrieve the list of ExtensionModule instances that have been evaluated as applicable for the current request. If this list has not yet been populated then use the ExtensibilityModuleHandler configured in the Spring application context to evaluate them.

Returns:

A list of ExtensionModule instances that are applicable to the current request.

getExtendedScriptConfigModel

public org.springframework.extensions.webscripts.ScriptConfigModel getExtendedScriptConfigModel(java.lang.String xmlConfig)

Creates a new ExtendedScriptConfigModel instance using the local configuration generated for this request. If configuration for the request will be generated if it does not yet exist. It is likely that this method will be called multiple times within the context of a single request and although the configuration containers will always be the same a new ExtendedScriptConfigModel instance will always be created as the the supplied xmlConfig string could be different for each call (because each WebScript invoked in the request will supply different configuration.

Specified by:

getExtendedScriptConfigModel in interface org.springframework.extensions.surf.extensibility.HandlesExtensibility

getExtendedTemplateConfigModel

public org.springframework.extensions.webscripts.TemplateConfigModel getExtendedTemplateConfigModel(java.lang.String xmlConfig)

Creates a new TemplateConfigModel instance using the local configuration generated for this request. If configuration for the request will be generated if it does not yet exist. It is likely that this method will be called multiple times within the context of a single request and although the configuration containers will always be the same a new TemplateConfigModel instance will always be created as the the supplied xmlConfig string could be different for each call (because each WebScript invoked in the request will supply different configuration.

Specified by:

getExtendedTemplateConfigModel in interface org.springframework.extensions.surf.extensibility.HandlesExtensibility

addExtensibilityDirectives

public void addExtensibilityDirectives(java.util.Map freeMarkerModel,
                              org.springframework.extensions.surf.extensibility.ExtensibilityModel extModel)
