- java.lang.Enum<TracingPolicy>
- - io.vertx.core.tracing.TracingPolicy

All Implemented Interfaces:

Serializable, Comparable<TracingPolicy>
```
public enum TracingPolicy
extends Enum<TracingPolicy>
```
Policy controlling the behavior across boundaries. This control is applied for clients or servers reporting traces.

Enum Constants
Enum Constant	Description
`ALWAYS`	Reuse an existing trace or create a new trace when no one exist.
`IGNORE`	Do not propagate a trace, this is equivalent of disabling tracing.
`PROPAGATE`	Propagate an existing trace.

  - PROPAGATE
```
public static final TracingPolicy PROPAGATE
```
    Propagate an existing trace.

- Method Detail
  - values
```
public static TracingPolicy[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (TracingPolicy c : TracingPolicy.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static TracingPolicy valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
