```
public abstract class DDTraceId

                    
```
Class encapsulating the id used for TraceIds.
It contains parsing and formatting to string for both decimal and hexadecimal representations. The string representations are either kept from parsing, or generated on demand and cached.

  - from
```
 static DDTraceId from(long id)
```
    Creates a new 64-bit TraceId from the given {@code long} interpreted asthe bits of the unsigned 64-bit id. This means that values larger than MAX_VALUE will be represented as negative numbers.
    
    Parameters:
    
    id - The {@code long} representing the bits of the unsigned 64-bit id.
  - from
```
 static DDTraceId from(String s)
```
    Creates a new 64-bit TraceId from the given String representation.
    
    Parameters:
    
    s - The String representation of a DDTraceId.
  - fromHex
```
 static DDTraceId fromHex(String s)
```
    Creates a new DDTraceId from the given hexadecimal representation.
    
    Parameters:
    
    s - The hexadecimal String representation of a DD128bTraceId to parse.
  - toString
```
 abstract String toString()
```
    Returns a 64-bit only decimal String representation of the DDTraceId. The String will be cached.
  - toHexString
```
 abstract String toHexString()
```
    Returns the lower-case zero-padded 32 hexadecimal characters String representation ofthe DDTraceId. The * String will be cached.
  - toHexStringPadded
```
 abstract String toHexStringPadded(int size)
```
    Returns the lower-case zero-padded hexadecimal String representation ofthe DDTraceId. The size will be rounded up to 16 or 32characters. This hexadecimal Stringwill not be cached.
    
    Parameters:
    
    size - The size in characters of the zero-padded String (rounded up to 16 or 32).
  - toLong
```
 abstract long toLong()
```
    Returns the low-order 64 bits of the DDTraceId as an unsigned {@code long}. This meansthat values larger than MAX_VALUE will be represented as negative numbers.
  - toHighOrderLong
```
 abstract long toHighOrderLong()
```
    Returns the high-order 64 bits of 128-bit DDTraceId as un unsigned {@code long}. Thismeans that values larger than MAX_VALUE will be represented as negative numbers.
