Method Detail

initialize

public void initialize()

Description copied from interface: IExtension

Extension's initialization code should be here. This method is called for all the extensions during Andami's initialization.

isEnabled

public boolean isEnabled()

Description copied from interface: IExtension

Returns:

true if the extension should be visible, false otherwise

isVisibleForTable

protected abstract boolean isVisibleForTable(TableDocument tableDocument)

Returns if the current extension is visible for the provided table. The provided table will be always non null.

Parameters:

layer - the active table

Returns:

if the extension is visible

protected TableDocument getActiveTableDocument()
                                        throws DataException

Returns the active table document. If the active document is not a table, or if the table has not a geometry, return null.

Returns:

the active table document

Throws:

DataException

isStoreOfAnyType

protected boolean isStoreOfAnyType(TableDocument tableDocument,
                       int[] geomTypes)

execute

public void execute(String actionCommand)
