serialize

Serialize PathPatternNode

• [required] 1 string: name. It specifies the name of node
• [required] 1 int: nodeType or size of valueSet.
  • If this node is being used by PathPatternTree, it specifies the type of this node. -1 means from root to the current node is a registered path pattern. Otherwise -2.
  • If this node is being used by PatternTreeMap, it specifies the size of valueSet which will be serialized next.(>=0)
• [optional] valueSet
• [required] 1 int: children size.
• [optional] children
