TraceAttributes (Oracle Database JDBC Java API Reference)

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.

    Returns the value to which the specified key is mapped, or null
    
    Parameters:
    
    key - the key whose associated value is to be returned
    
    Returns:
    
    the value to which the specified key is mapped, or null if this map contains no mapping for the key
    
    Throws:
    
    java.lang.ClassCastException - if the key is of an inappropriate type for this map (optional)
    
    java.lang.NullPointerException - if the specified key is null and this map does not permit null keys (optional)
  - iterator
```
public java.util.Iterator<TraceAttributes.Entry> iterator()
```
    Returns an iterator over Entries.
    
    Specified by:
    
    iterator in interface java.lang.Iterable<TraceAttributes.Entry>
    
    Returns:
    
    an Iterator.
