extends com.google.api.client.json.GenericJson
```
A span represents a single operation within a trace. Spans can be nested to form a trace tree. Often, a trace contains a root span that describes the end-to-end latency, and one or more subspans for its sub-operations. A trace can also contain multiple root spans, or none at all. Spans do not need to be contiguousthere may be gaps or overlaps between spans in a trace.
This is the Java data model class that specifies how to parse/serialize into the JSON that is transmitted over HTTP when working with the Cloud Trace API. For a detailed explanation see: https://developers.google.com/api-client-library/java/google-http-java-client/json

- Constructor Detail
  - Span
```
public Span()
```
- Method Detail
  - getAttributes
```
public Attributes getAttributes()
```
    A set of attributes on the span. You can have up to 32 attributes per span.
    
    Returns:
    
    value or null for none
  - setAttributes
```
public Span setAttributes(Attributes attributes)
```
    A set of attributes on the span. You can have up to 32 attributes per span.
    
    Parameters:
    
    attributes - attributes or null for none
  - getChildSpanCount
```
public java.lang.Integer getChildSpanCount()
```
    Optional. The number of child spans that were generated while this span was active. If set, allows implementation to detect missing child spans.
    
    Returns:
    
    value or null for none
  - setChildSpanCount
```
public Span setChildSpanCount(java.lang.Integer childSpanCount)
```
    Optional. The number of child spans that were generated while this span was active. If set, allows implementation to detect missing child spans.
    
    Parameters:
    
    childSpanCount - childSpanCount or null for none
  - getDisplayName
```
public TruncatableString getDisplayName()
```
    Required. A description of the span's operation (up to 128 bytes). Stackdriver Trace displays the description in the Google Cloud Platform Console. For example, the display name can be a qualified method name or a file name and a line number where the operation is called. A best practice is to use the same display name within an application and at the same call point. This makes it easier to correlate spans in different traces.
    
    Returns:
    
    value or null for none
  - setDisplayName
```
public Span setDisplayName(TruncatableString displayName)
```
    Required. A description of the span's operation (up to 128 bytes). Stackdriver Trace displays the description in the Google Cloud Platform Console. For example, the display name can be a qualified method name or a file name and a line number where the operation is called.

public java.lang.String getEndTime()
```
    Required. The end time of the span. On the client side, this is the time kept by the local machine where the span execution ends. On the server side, this is the time when the server application handler stops running.
    
    Returns:
    
    value or null for none
