func ListAstNode 

func ListAstNode[T googlesql.ASTNode](n *googlesql.ASTScript) []T

func ListResolvedAstNode 

func ListResolvedAstNode[T googlesql.ResolvedNode](output *googlesql.AnalyzerOutput) []T

func LookupNode 

func LookupNode[T astNode](n googlesql.ASTNode) (T, bool)

func ParseLocEnd added in v0.5.0 

func ParseLocEnd(loc *googlesql.ParseLocationRange) int

func ParseLocStart added in v0.5.0 

func ParseLocStart(loc *googlesql.ParseLocationRange) int

ParseLocStart/End are exported wrappers for use from other packages.

func SearchAstNode 

func SearchAstNode[T googlesql.ASTNode](node googlesql.ASTNode, termOffset int) (T, bool)

func SearchResolvedAstNode 

func SearchResolvedAstNode[T googlesql.ResolvedNode](output *googlesql.AnalyzerOutput, termOffset int) (T, bool)

func Walk added in v0.5.0 

func Walk(node googlesql.ASTNode, fn func(googlesql.ASTNode) error) error
