@Generated("software.amazon.awssdk:codegen")
public final class SamplingRule
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<SamplingRule.Builder,SamplingRule>
```
A sampling rule that services use to decide whether to instrument a request. Rule fields can match properties of the service, or properties of a request. The service can ignore rules that don't match its properties.

- Method Detail
  - ruleName
```
public final String ruleName()
```
    The name of the sampling rule. Specify a rule by either name or ARN, but not both.
    
    Returns:
    
    The name of the sampling rule. Specify a rule by either name or ARN, but not both.
  - ruleARN
```
public final String ruleARN()
```
    The ARN of the sampling rule. Specify a rule by either name or ARN, but not both.
    
    Returns:
    
    The ARN of the sampling rule. Specify a rule by either name or ARN, but not both.
  - resourceARN
```
public final String resourceARN()
```
    Matches the ARN of the Amazon Web Services resource on which the service runs.
    
    Returns:
    
    Matches the ARN of the Amazon Web Services resource on which the service runs.
  - priority
```
public final Integer priority()
```
    The priority of the sampling rule.
    
    Returns:
    
    The priority of the sampling rule.
  - fixedRate
```
public final Double fixedRate()
```
    The percentage of matching requests to instrument, after the reservoir is exhausted.
    
    Returns:
    
    The percentage of matching requests to instrument, after the reservoir is exhausted.
  - reservoirSize
```
public final Integer reservoirSize()
```
    A fixed number of matching requests to instrument per second, prior to applying the fixed rate. The reservoir is not used directly by services, but applies to all services using the rule collectively.
    
    Returns:
    
    A fixed number of matching requests to instrument per second, prior to applying the fixed rate. The reservoir is not used directly by services, but applies to all services using the rule collectively.
  - serviceName
```
public final String serviceName()
```
    Matches the name that the service uses to identify itself in segments.
    
    Returns:
    
    Matches the name that the service uses to identify itself in segments.
  - serviceType
```
public final String serviceType()
```
    Matches the origin that the service uses to identify its type in segments.
    
    Returns:
    
    Matches the origin that the service uses to identify its type in segments.
  - host
```
public final String host()
```
    Matches the hostname from a request URL.
    
    Returns:
    
    Matches the hostname from a request URL.
  - httpMethod
```
public final String httpMethod()
```
    Matches the HTTP method of a request.
    
    Returns:
    
    Matches the HTTP method of a request.
  - urlPath
```
public final String urlPath()
```
    Matches the path from a request URL.
    
    Returns:
    
    Matches the path from a request URL.
  - version
```
public final Integer version()
```
    The version of the sampling rule format (1).
    
    Returns:
    
    The version of the sampling rule format (1).
  - hasAttributes
```
public final boolean hasAttributes()
```
    For responses, this returns true if the service returned a value for the Attributes property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - attributes
```
public final Map<String,String> attributes()
```
    Matches attributes derived from the request.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAttributes() method.
    
    Returns:
    
    Matches attributes derived from the request.
  - toBuilder

```
    Specified by:
    
    toBuilder in interface ToCopyableBuilder<SamplingRule.Builder,SamplingRule>
  - builder
