Class TraceAttributes

java.lang.Object

oracle.jdbc.diagnostics.TraceAttributes

All Implemented Interfaces:

java.io.Serializable, java.lang.Iterable<TraceAttributes.Entry>

Direct Known Subclasses:

ImmutableTraceAttributes, MutableTraceAttributes

public abstract class TraceAttributes
extends java.lang.Object
implements java.lang.Iterable<TraceAttributes.Entry>, java.io.Serializable

A fast, compact implementation of Map<ConnectionAttribute, String>. Diagnostics creates many of these so they need to be small and fast. Since the keys are a known enum, the values are stored in an array indexed by the enum ordinal. Null values are not allowed.
