----------------------------------
Summary: Implement Marker File precondition
Key: OODT-451
URL: https://issues.apache.org/jira/browse/OODT-451
Project: OODT
Issue Type: Improvement
Components: metadata container
Affects Versions: 0.3
Reporter: Luca Cinquini
Fix For: 0.4
Sometimes it is necessary to process a product directory only when the
directory has been fully produced, or transferred, which can be indicated by
the existence of a special "marker file". It is suggested that we implement a
precondition that checks for the existence of a given file within a given
product. This precondition would be implemented similarly to
org.apache.oodt.cas.metadata.preconditions.ExistanceCheckComparator, but would
check for a file at location:
File file = new File(product.getAbsolutePath()+"/"+filePath);
