Types ¶
type ObjectVal ¶
type ObjectVal struct {
// contains filtered or unexported fields
}
ObjectVal is the CEL Val for an object that is constructed via the object construction syntax.
func NewObjectVal ¶
func NewObjectVal(typeRef TypeRef, fields map[string]ref.Val) *ObjectVal
NewObjectVal creates an ObjectVal by its TypeRef and its fields.
func (*ObjectVal) ConvertToNative ¶
func (v *ObjectVal) ConvertToNative(typeDesc reflect.Type) (any, error)
ConvertToNative converts the object to map[string]any. All nested lists are converted into []any native type.
It returns an error if the target type is not map[string]any, or any recursive conversion fails.
func (*ObjectVal) ConvertToType ¶
func (v *ObjectVal) ConvertToType(typeValue ref.Type) ref.Val
ConvertToType supports type conversions between CEL value types supported by the expression language.
func (*ObjectVal) Equal ¶
func (v *ObjectVal) Equal(other ref.Val) ref.Val
Equal returns true if the `other` value has the same type and content as the implementing struct.
func (*ObjectVal) IsZeroValue ¶
func (v *ObjectVal) IsZeroValue() bool
IsZeroValue indicates whether the object is the zero value for the type. For the ObjectVal, it is zero value if and only if the fields map is empty.
type TypeRef ¶
type TypeRef interface {
ref.Type
// CELType wraps the TypeRef to be a type that is understood by CEL.
CELType() *types.Type
// Field finds the field by the field name, or false if the field is not known.
// This function directly return a FieldType that is known to CEL to be more customizable.
Field(name string) (*types.FieldType, bool)
// Val creates an instance for the TypeRef, given its fields and their values.
Val(fields map[string]ref.Val) ref.Val
}
TypeRef refers an object type that can be looked up for its fields.
type TypeResolver ¶
type TypeResolver interface {
// Resolve resolves the type by its name, starting with "Object" as its root.
// The type that the name refers to must be an object.
// This function returns false if the name does not refer to a known object type.
Resolve(name string) (TypeRef, bool)
}
TypeResolver resolves a type by a given name.
