[jira] [Updated] (UIMA-4381) speed up flat iterator concurrent mod check

     [ https://issues.apache.org/jira/browse/UIMA-4381?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Marshall Schor updated UIMA-4381:
---------------------------------
    Description: The concurrent modification check is done frequently (e.g., on each "get", etc.)  It requires finding a value mapped from a type code (for the particular type / subtype involved). Change this map from a simple lookup (loop over all typecodes in the map looking for the right one) to a binary search one.   (was: The concurrent modification check is done frequently (e.g., on each "get", etc.)  It requires finding a value mapped from a type code (for the particular type / subtype involved). Change this map from a simple lookup (loop over all typecodes in the map looking for the right one) to a binary search one.  And arrange to share the keys with all flat iterators using them. )
