Constructor Detail

### AbstractRepositorySource

    public AbstractRepositorySource()

Method Detail

### areUpdatesAllowed

    public boolean areUpdatesAllowed()

  Get whether this source allows updates.

  Specified by:
    `areUpdatesAllowed` in interface `BaseRepositorySource`

    true if this source allows updates by clients, or false if no updates are allowed
  See Also:
    `BaseRepositorySource.areUpdatesAllowed()`

### isCreatingWorkspacesAllowed

    public boolean isCreatingWorkspacesAllowed()

  Get whether this source allows workspaces to be created.

  Specified by:
    `isCreatingWorkspacesAllowed` in interface `BaseRepositorySource`
  Returns:
    true if this source allows workspaces to be created by clients, or false if creating workspaces is not allowed
  See Also:
    `BaseRepositorySource.isCreatingWorkspacesAllowed()`

### getRepositoryContext

    public RepositoryContext getRepositoryContext()

  Returns the `repository context` for the repository source

  Specified by:
    `getRepositoryContext` in interface `BaseRepositorySource`
  Returns:
    the `repository context` for the repository source
  See Also:
    `BaseRepositorySource.getRepositoryContext()`

### initialize

    public void initialize(RepositoryContext context)
                    throws RepositorySourceException

  Initialize this source to use the supplied `RepositoryContext`, from which this source can obtain the `configuration` defining this source, `connections` to other `sources`, and the `execution context`.

  This method may be called each time the configuration changes, allowing the source to update itself.

  Specified by:
    `initialize` in interface `RepositorySource`
  Throws:
    `RepositorySourceException`
  See Also:
    `RepositorySource.initialize(RepositoryContext)`

### getDefaultCachePolicy

    public CachePolicy getDefaultCachePolicy()

  Returns the `cache policy` for the repository source

  Specified by:
    `getDefaultCachePolicy` in interface `BaseRepositorySource`
  Returns:
    the `cache policy` for the repository source
  See Also:
    `BaseRepositorySource.getDefaultCachePolicy()`

### setCachePolicy

    public void setCachePolicy(CachePolicy cachePolicy)

  Sets the cache policy for the repository and replaces the path repository cache with a new path repository cache tied to the new cache policy

  Parameters:
    `cachePolicy` - the new cache policy; may not be null

### getRootNodeUuidObject

    public UUID getRootNodeUuidObject()

  Get the UUID for the root node.

  Specified by:
    `getRootNodeUuidObject` in interface `BaseRepositorySource`
  Returns:
    the root node's UUID; may not be null
  See Also:
    `BaseRepositorySource.getRootNodeUuidObject()`

### setRootNodeUuidObject

    public void setRootNodeUuidObject(String rootNodeUuid)

  Parameters:
    `rootNodeUuid` - Sets rootNodeUuid to the specified value.
  Throws:
    `IllegalArgumentException` - if the string value cannot be converted to UUID

### getRootNodeUuid

    public String getRootNodeUuid()

  Get the UUID of the root node for the cache. If the cache exists, this UUID is not used but is instead set to the UUID of the existing root node.

  Returns:
    the UUID of the root node for the cache.

### setRootNodeUuid

    public void setRootNodeUuid(String rootNodeUuid)

  Set the UUID of the root node in this repository. If the cache exists, this UUID is not used but is instead set to the UUID of the existing root node.

  Parameters:
    `rootNodeUuid` - the UUID of the root node for the cache, or null if the UUID should be randomly generated

### close

    public void close()

  Signal this source that it is no longer needed and should begin the process of reclaiming or closing all resources that it has acquired. Because `connections` may still be in use, this method may not necessarily close all resources immediately.

  This is a required method, and must be called when this source is no longer needed if one or more `connections` have been obtained since the previous call to this method.

  Note that calling this method also does not preclude `obtaining more connections` after this method is called. If that happens, this source should simply reacquire any resources necessary to provide additional connections, and this method needs to be called once again.

  Specified by:
    `close` in interface `RepositorySource`
  See Also:
    `RepositorySource.close()`

### getName

    public String getName()

  Get the name for this repository source.

  Specified by:
    `getName` in interface `RepositorySource`
  Returns:
    the name; never null or empty
  See Also:
    `RepositorySource.getName()`

### setName

    public void setName(String name)

  Sets the name of the repository source. The name should be unique among loaded repository sources.

  Parameters:
    `name` - the new name for the repository source; may not be empty

### getRetryLimit

    public int getRetryLimit()

  Get the maximum number of retries that may be performed on a given operation when using `connections` created by this source. This value does not constitute a minimum number of retries; in fact, the connection user is not required to retry any operations.

  Specified by:
    `getRetryLimit` in interface `RepositorySource`
  Returns:
    the maximum number of allowable retries, or 0 if the source has no limit
  See Also:
    `RepositorySource.getRetryLimit()`

### setRetryLimit

    public void setRetryLimit(int limit)

  Set the maximum number of retries that may be performed on a given operation when using `connections` created by this source. This value does not constitute a minimum number of retries; in fact, the connection user is not required to retry any operations.

  Specified by:
    `setRetryLimit` in interface `RepositorySource`
  Parameters:
    `limit` - the maximum number of allowable retries, or 0 if the source has no limit
  See Also:
    `RepositorySource.setRetryLimit(int limit)`

### valuesFrom

    protected Map<String,Object> valuesFrom(Reference ref)
                                     throws IOException,
                                            ClassNotFoundException

  Extracts the values from the given reference, automatically translating `BinaryRefAddr` instances into the deserialized classes that they represent.

  Parameters:
    `ref` - the reference from which the values should be extracted
  Returns:
    a map of value names to values from the reference
  Throws:
    `IOException` - if there is an error deserializing a `BinaryRefAddr`
    `ClassNotFoundException` - if a serialized class cannot be deserialized because its class is not in the class path
