Here is the caller graph for this function:

getmeta()

IMetadata * NodeMetaRef::getmeta ( bool auto_create )

privatevirtual

Retrieve metadata for a node.

If auto_create is set and the specified node has no metadata information associated with it yet, the method attempts to attach a new metadata object to the node and returns a pointer to the metadata when successful.

However, it is NOT guaranteed that the method will return a pointer, and NULL may be returned in case of an error regardless of auto_create.

Parameters

ref	specifies the node for which the associated metadata is retrieved.
auto_create	when true, try to create metadata information for the node if it has none.

Returns

pointer to a NodeMetadata object or NULL in case of error.

Implements MetaDataRef.
