Class AttributeSourcesChain.Merge

java.lang.Object
  eu.emi.dsr.security.util.AttributeSourcesChain.Merge

All Implemented Interfaces:

AttributeSourcesChain.CombiningPolicy

Enclosing class:

AttributeSourcesChain

public static class AttributeSourcesChain.Merge
extends Object
implements AttributeSourcesChain.CombiningPolicy

Merge: attributes with the same key are combined (values are added). This is always OK for XACML attributes (only duplicates are not maintained) and for lists of valid values. However for regular incarnation attributes (like xlogin, role, primary gid, queue) only one value make sense. So in case of default values obtained from AS of incarnation attributes the same policy is used as in MERGE_LAST_OVERRIDS.
