Method Detail

nextComponentUuid

public java.lang.String nextComponentUuid(Desktop desktop,
                                          Component comp)

Description copied from interface: IdGenerator

Returns the next component UUID for the specified component, or null to generate the default UUID.

Default (if null is returned): UUID is generated by prefixing a portion of the desktop's ID with a number starting from 0.

This method is called when Component.getUuid() is called at the first time. It is usually when the component is attached to a page, unless the application invokes Component.getUuid() earlier.

Specified by:

nextComponentUuid in interface IdGenerator

Parameters:

desktop - the current desktop (never null)

comp - the component (never null)

Returns:

the next component UUID, or null to generate the default UUID.
Note: don't return an UUID containing ':'.

nextPageUuid

public java.lang.String nextPageUuid(Page page)

Description copied from interface: IdGenerator

Returns the next page UUID for the specified page, or null to generate the default UUID.

Default (if null is returned): UUID is generated by prefixing a portion of the desktop's ID with a number starting from 0.

Note: we can retrieve the execution by use of Executions.getCurrent().

Specified by:

nextPageUuid in interface IdGenerator

Returns:

the next page UUID, or null to generate the default UUID.

nextDesktopId

public java.lang.String nextDesktopId(Desktop desktop)

Description copied from interface: IdGenerator

Returns the next desktop ID for the specified desktop, or null to generate the default ID.

Default (if null is returned): ID is generated randomly. In other words, the desktop's ID, by default, is not deterministic. To have a deterministric value, you have to implement this method.

Note: we can retrieve the execution by use of Desktop.getExecution(), or Executions.getCurrent().

Specified by:

nextDesktopId in interface IdGenerator

Returns:

the next desktop ID, or null to generate the default ID.
