Comparing the old and new methods, we find that using slice makes the parsing 20% faster on average than using channels. Also, using slices allows the parser to backtrack and peek the tokens which couldn't be done using channels as each token can only be consumed once.

Types ¶
type FilterTree ¶ added in v0.7.0
type FilterTree struct {
Op string
Child []*FilterTree
Func *Function
}
FilterTree is the result of parsing the filter directive. Either you can have `Op and Children` on non-leaf nodes Or Func at leaf nodes.
type Function ¶ added in v0.7.0
type Function struct {
Attr string
Name string // Specifies the name of the function.
Args []string // Contains the arguments of the function.
NeedsVar []string // If the function requires some variable
}
Function holds the information about gql functions.
func (*Function) IsAggregator ¶ added in v0.7.3
func (*Function) IsPasswordVerifier ¶ added in v0.7.3
type GraphQuery ¶
type GraphQuery struct {
UID []uint64
Attr string
Langs []string
Alias string
IsCount bool
Var string
NeedsVar []string
Func *Function
Args map[string]string
Children []*GraphQuery
Filter *FilterTree
Normalize bool
Facets *Facets
FacetsFilter *FilterTree
// 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.
func (*GraphQuery) DebugPrint ¶ added in v0.7.0
func (gq *GraphQuery) DebugPrint(prefix string)
DebugPrint is useful for debugging.
type Result ¶ added in v0.7.2
type Result struct {
Query []*GraphQuery
QueryVars []*Vars
Mutation *Mutation
}
Result struct contains the Query list, its corresponding variable use list and the mutation block.
