Functions

func Parse

func Parse(input string) (gq *GraphQuery, mu *Mutation, rerr error)

Parse initializes and runs the lexer. It also constructs the GraphQuery subgraph from the lexed items.

Types

type GraphQuery

type GraphQuery struct {
	UID      uint64
	XID      string
	Attr     string
	Args     map[string]string
	Children []*GraphQuery
	// contains filtered or unexported fields
}

GraphQuery stores the parsed Query in a tree format. This gets converted to internally used query.SubGraph before processing the query.

type Mutation

type Mutation struct {
	Set string
	Del string
}

Mutation stores the strings corresponding to set and delete operations.
