public class InMemoryRepositorySource
A RepositorySource
for an in-memory repository. Each InMemoryRepositorySource
instance contains its own
repository, and the lifetime of the source dictates the lifetime of the repository and its content.
Field Summary | |

static int |
DEFAULT_RETRY_LIMIT
The default limit is 0 for retrying connection calls to the underlying source. |
static String |
DEFAULT_WORKSPACE_NAME
The default name for the workspace used by this source, which is a blank string. |
Constructor Summary | |

public void initialize(RepositoryContext context) throws RepositorySourceException
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.

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.
