Field Summary

Fields
Modifier and Type	Field	Description
`int`	`arcIdx`	Where we are in the array; only valid if bytesPerArc != 0.
`int`	`bytesPerArc`	Non-zero if this arc is part of an array, which means all arcs for the node are encoded with a fixed number of bytes so that we can random access by index.
`int`	`label`
`T`	`nextFinalOutput`
`int`	`numArcs`	How many arcs in the array; only valid if bytesPerArc != 0.
`T`	`output`
`long`	`posArcsStart`	Where the first arc in the array starts; only valid if bytesPerArc != 0
`long`	`target`	To node (ord or address)

    Non-zero if this arc is part of an array, which means all arcs for the node are encoded with a fixed number of bytes so that we can random access by index. We do when there are enough arcs leaving one node. It wastes some bytes but gives faster lookups.
  - arcIdx
```
public int arcIdx
```
    Where we are in the array; only valid if bytesPerArc != 0.
  - numArcs
```
public int numArcs
```
    How many arcs in the array; only valid if bytesPerArc != 0.
