clean

public void clean(java.util.Set clientStringCellKeySet)

Description copied from class: ClientKeyManager

Prunes the client-side key cache based on which cell keys are still in the client. This is typically done on the pivot table after some client keys on the client are removed. This is done to prevent a memory leak when we are short scrolling over a large amount of data and accumulating client keys when each new block is brought to the client.

Specified by:

clean in class ClientKeyManager

clear

public void clear()

Description copied from class: ClientKeyManager

Clears the client-side key cache. This is typically done on a re-render of the pivot table or after all references to client keys on the client are removed / client blocks are removed.

Specified by:

clear in class ClientKeyManager

getCellKey

public CellKey getCellKey(javax.faces.context.FacesContext context,
                          javax.faces.component.UIComponent component,
                          java.lang.String clientCellKey)

Gets the corresponding server-side cellkey object from the given client-side string key. If the string key has expired, implementors should return null. However, if any part of a cell is still present on the client-side, its corresponding string-key may not expire.

Specified by:

getCellKey in class ClientKeyManager

Parameters:

context - the Faces context

component - the UI component

clientCellKey - the string key

Returns:

the cell key, or null if the string key has expired or never existed

getClientCellKey

public java.lang.String getClientCellKey(javax.faces.context.FacesContext context,
                                         javax.faces.component.UIComponent component,
                                         CellKey cellKey)

Gets a string version of a key that identifies the cell with the given cellkey. This string key can be used on the client-side to identify the cell. If a string key for the given cellkey does not exist, then a new one is created. The lifespan of this string cellkey is entirely up to each implementation. Implementors must ensure that if a particular cell is still present on the client-side, then its string key must also continue to be valid.

Specified by:

getClientCellKey in class ClientKeyManager

Parameters:

context - the Faces context

component - the UI component

cellKey - the cellkey to convert into a client key. Note that null is special and is not allowed.

Returns:
