Types

type Aspect

type Aspect interface {
	// Pointcut returns the pointcut for the aspect.
	// Pointcut is executed on compilation-time.
	Pointcut() Pointcut

	// Advice executes the "around" advice.
	// User must be careful about the length and the type of
	// the []interface{} slice.
	// The slice can be empty []interface{}{}, but cannot be nil.
	Advice(Context) []interface{}
}

Aspect is the interface for aspect definition. Currently, only "around" type advice is supported.

type Context

type Context interface {
	// Args returns the original argument set for the joinpoint.
	// The slice can be empty []interface{}{}, but cannot be nil.
	Args() []interface{}

	// Call calls the joinpoint.
	// User must be careful about the length and the type of
	// the []interface{} slices.
	// The slices can be empty []interface{}{}, but cannot be nil.
	Call([]interface{}) []interface{}

	// Receiver returns the receiver for methods.
	// For non-method function, it just returns nil.
	Receiver() interface{}
}

Context is the type for joinpoint context definition.

type Pointcut
