Types

type BaseNode

type BaseNode struct {
	// contains filtered or unexported fields
}

func (*BaseNode) GetRegistry

func (n *BaseNode) GetRegistry() *NodeRegistry

func (*BaseNode) SetRegistry

func (n *BaseNode) SetRegistry(registry *NodeRegistry)

type Field

type Field struct {
	// contains filtered or unexported fields
}

Field a Field represents a component of the Node abstraction, corresponding to an attribute of a business object. Field is used to define and represent a single data point within a Node, such as a user's name, age, etc.

func NewNodeField

func NewNodeField(fieldName string, fieldType FieldType) *Field

func (*Field) Convert

func (f *Field) Convert(hub *NodeRegistry) (field *graphql.Field, err error)

Convert Field对象不仅需要转换成graphql.Field对象，同时要根据自身的数据类型，生成相应的ArgumentConfig 当 Field 是一个对象类型时，将会递归调用 NodeRegistry.buildNode 方法，优先初始化对应的Node，

func (*Field) Resolver

func (f *Field) Resolver() graphql.FieldResolveFn

func (*Field) SetResolver

func (f *Field) SetResolver(resolver graphql.FieldResolveFn)

type FieldType

type FieldType string

const (
	FieldTypeString  FieldType = "String"
	FieldTypeInt     FieldType = "Int"
	FieldTypeFloat   FieldType = "Float"
	FieldTypeBoolean FieldType = "Boolean"
)

type Node

type Node interface {
	// Name query name
	// users{ <- this is the query name
	//   id
	//   name
	//   email
	// }
	Name() string
	// Type NodeType
	Type() FieldType

	Resolve() graphql.FieldResolveFn
	BuildFields() []*Field
	BuildArgs() []argument.Argument

	IsList() bool

	GetRegistry() *NodeRegistry
	SetRegistry(*NodeRegistry)
}

Node a Node represents a fundamental business object, serving as the core unit for constructing GraphQL queries. As an abstract concept, Node allows developers to define and declare their business data models. These models are then transformed by the framework into GraphQL query structures.

type NodeRegistry

type NodeRegistry struct {
	// contains filtered or unexported fields
}

NodeRegistry is a key component in the go-gql-builder framework, serving as a repository for storing and managing the implementations of Node declared by developers.

func DefaultRegistry

func DefaultRegistry() *NodeRegistry

func NewRegistry

func NewRegistry() *NodeRegistry

func (*NodeRegistry) BuildHandler

func (h *NodeRegistry) BuildHandler() (http.Handler, error)

func (*NodeRegistry) GetDB

func (h *NodeRegistry) GetDB() *sql.DB

func (*NodeRegistry) Register

func (h *NodeRegistry) Register(delegate Node)

func (*NodeRegistry) SetDB

func (h *NodeRegistry) SetDB(db *sql.DB)
