setRegistryStoreRef

public void setRegistryStoreRef(org.alfresco.service.cmr.repository.StoreRef registryStoreRef)

Parameters:

registryStoreRef - the store in which the registry root is found

setRegistryStore

public void setRegistryStore(String registryStore)

setRegistryRootPath

public void setRegistryRootPath(String registryRootPath)

A root path e.g. /sys:systemRegistry

value - any value that can be stored in the repository.

getProperty

public Serializable getProperty(RegistryKey key)

Specified by:

getProperty in interface RegistryService

Parameters:

key - the registry key.

Returns:

Returns the value stored in the key or null if no value exists at the path and name provided

See Also:

RegistryService.addProperty(RegistryKey, Serializable)

getChildElements

public Collection<String> getChildElements(RegistryKey key)

Description copied from interface: RegistryService

Fetches all child elements for the given path. The key's property should be null as it is completely ignored.

    ...
    registryService.addValue(KEY_A_B_C_1, VALUE_ONE);
    registryService.addValue(KEY_A_B_C_2, VALUE_TWO);
    ...
    assertTrue(registryService.getChildElements(KEY_A_B_null).contains("C"));
    ...
 

Specified by:

getChildElements in interface RegistryService

Parameters:

key - the registry key with the path. The last element in the path will be ignored, and can be any acceptable value localname or null.

Returns:

Returns all child elements (not values) for the given key, ignoring the last element in the key.

RegistryKey.getPath()

copy

public void copy(RegistryKey sourceKey,
                 RegistryKey targetKey)

Description copied from interface: RegistryService

Copies the path or value from the source to the target location. The source and target keys must be both either path-specific or property-specific. If the source doesn't exist, then nothing will be done; there is no guarantee that the target will exist after the call.

This is essentially a merge operation. Use delete first if the target must be cleaned.

Specified by:

copy in interface RegistryService

Parameters:

sourceKey - the source registry key to take values from

targetKey - the target registyr key to move the path or value to

delete

public void delete(RegistryKey key)

Description copied from interface: RegistryService

Delete the path element or value described by the key. If the key points to nothing, then nothing is done. delete(/a/b/c) will remove value c from path /a/b.
delete(/a/b/null) will remove node /a/b along with all values and child elements.

Specified by:

delete in interface RegistryService

Parameters:

key - the path or value to delete
