Field Detail

EMPTY

protected static final ContextAttributes.Impl EMPTY

NULL_SURROGATE

protected static final java.lang.Object NULL_SURROGATE

_shared

protected final java.util.Map<?,?> _shared

Shared attributes that we cannot modify in-place.

_nonShared

protected transient java.util.Map<java.lang.Object,java.lang.Object> _nonShared

Per-call attributes that we can directly modify, since they are not shared between threads.

NOTE: typed as Object-to-Object, unlike _shared, because we need to be able to modify contents, and wildcard type would complicate that access.
