Method Detail

getOperation

public ServletOperation getOperation(org.apache.sling.api.SlingHttpServletRequest request,
                                     ServletOperationSet.Method method)

Retrieves the servlet operation requested for the used HTTP method. Looks in the selectors for a operation and gives their implementation in the extensions context.

Parameters:

request - the servlet request

method - the requested HTTP method

Returns:

the operation or 'null', if the requested combination of selector and extension has no implementation for the given HTTP method

setOperation

public void setOperation(ServletOperationSet.Method method,
                         E extension,
                         O operation,
                         ServletOperation implementation)

setOperation

public void setOperation(ServletOperationSet.Method method,
                         E extension,
                         O operation,
                         ServletOperation implementation,
                         boolean isDefault)

getDefaultOperation

public O getDefaultOperation(ServletOperationSet.Method method,
                             E extension)

setDefaultOperation

public void setDefaultOperation(ServletOperationSet.Method method,
                                E extension,
                                O operation)
