Overview

Package object defines the standard set of object types in Tamarin.

For external users of Tamarin, often an object.Object interface will be type asserted to a specific object type, such as *object.Float.

For example: 

switch obj := obj.(type) {
case *object.String:
	// do something with obj.Value()
case *object.Float:
	// do something with obj.Value()
}

The Type() method of each object may also be used to get a string name of the object type, such as "string" or "float".

func ResolveIndex 

func ResolveIndex(idx int64, size int64) (int64, error)

ResolveIndex checks that the index is inbounds and transforms a negative index into the corresponding positive index. If the index is out of bounds, an error is returned.

func ResolveIntSlice 

func ResolveIntSlice(slice Slice, size int64) (start int64, stop int64, err error)

type TypeConverter 

type TypeConverter interface {

	// To converts a Tamarin object to a Go object.
	To(Object) (interface{}, error)

	// From converts a Go object to a Tamarin object.
	From(interface{}) (Object, error)

	// Type that this TypeConverter is responsible for.
	Type() reflect.Type
}

TypeConverter is an interface used to convert between Go and Tamarin objects for a single Go type. There may be a way to use generics here...

type TypeRegistryOpts 

type TypeRegistryOpts struct {
	// Converters is a list of TypeConverters that will be used to convert
	// input and output types for method calls.
	Converters []TypeConverter

	// NoDefaults indicates that the default TypeConverters should not be
	// automatically used by the registry. If this is set, the caller should
	// provide their own TypeConverters.
	NoDefaults bool
}

TypeRegistryOpts contains options used to create a GoTypeRegistry.
