Classes

c Lexer	Given a Source object, creates a Lexer for that source. A Lexer is a stateful stream generator in that every time it is advanced, it returns the next token in the Source. Assuming the source lexes, the final Token emitted by the lexer will be of kind EOF, after which the lexer will repeatedly return the same EOF token whenever called.
c Source	A representation of source input to GraphQL. `name` and `locationOffset` are optional. They are useful for clients who store GraphQL documents in source files; for example, if the GraphQL input starts at line 40 in a file named Foo.graphql, it might be useful for name to be "Foo.graphql" and location to be `{ line: 40, column: 0 }`. line and column in locationOffset are 1-indexed

Variables

v BREAK
v DirectiveLocation	The set of allowed directive location values.
v Kind	The set of allowed kind values for AST nodes.
v TokenKind	An exported enum describing the different kinds of tokens that the lexer emits.

Functions

f getLocation	Takes a Source and a UTF-8 character offset, and returns the corresponding line and column as a SourceLocation.
f getVisitFn	Given a visitor instance, if it is leaving or not, and a node kind, return the function the visitor runtime should call.
f isDefinitionNode
f isExecutableDefinitionNode
f isSelectionNode
f isTypeDefinitionNode
f isTypeExtensionNode
f isTypeNode
f isTypeSystemDefinitionNode
f isTypeSystemExtensionNode
f isValueNode
f parse	Given a GraphQL source, parses it into a Document. Throws GraphQLError if a syntax error is encountered.
f parseType	Given a string containing a GraphQL Type (ex. `[Int!]`), parse the AST for that type. Throws GraphQLError if a syntax error is encountered.
f parseValue	Given a string containing a GraphQL value (ex. `[42]`), parse the AST for that value. Throws GraphQLError if a syntax error is encountered.
f print	Converts an AST into a string, using one set of reasonable formatting rules.
f printLocation	Render a helpful description of the location in the GraphQL Source document.
f printSourceLocation	Render a helpful description of the location in the GraphQL Source document.
f visit	visit() will walk through an AST using a depth first traversal, calling the visitor's enter function at each node in the traversal, and calling the leave function after visiting that node and all of its child nodes.
f visitInParallel	Creates a new visitor instance which delegates to many visitors to run in parallel. Each visitor will be visited for each node before moving on.
