Types

type AstNode

type AstNode interface {
	// Connect connects this AstNode to another AstNode with the given predicate,
	// and returns the same AstNode.
	Connect(predicate string, other AstNode) AstNode

	// Decorate decorates this AstNode with the given property and string value,
	// and returns the same AstNode.
	Decorate(property string, value string) AstNode

	// Decorate decorates this AstNode with the given property and int value,
	// and returns the same AstNode.
	DecorateWithInt(property string, value int) AstNode
}

AstNode defines an interface for working with nodes created by this parser.

type NodeBuilder

type NodeBuilder func(source compilercommon.InputSource, kind generic.U) AstNode
