type BundleSource 

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

The assorted methods largely pass through to the underlying bundle, but do so through an atomic pointer so that gross go-routine reads are not vulnerable to out-of-order execution memory type bugs.

func NewBundleSource 

func NewBundleSource(bundle *Bundle, callbacks ...func(*Bundle)) *BundleSource

NewBundleSource creates a new BundleSource with an initial Bundle value The callbacks will be invoked whenever the Update method is called for the BundleSource. Note, these callbacks are called immediately before this function returns.

func (*BundleSource) ApplicationConfig

func (bs *BundleSource) PolicyManager() policies.Manager

PolicyManager returns the policy manager constructed for this config

func (*BundleSource) StableBundle 

func (bs *BundleSource) StableBundle() *Bundle

StableBundle returns a pointer to a stable Bundle. It is stable because calls to its assorted methods will always return the same result, as the underlying data structures are immutable. For instance, calling BundleSource.Orderer() and BundleSource.MSPManager() to get first the list of orderer orgs, then querying the MSP for those org definitions could result in a bug because an update might replace the underlying Bundle in between. Therefore, for operations which require consistency between the Bundle calls, the caller should first retrieve a StableBundle, then operate on it.

func (bs *BundleSource) Update(newBundle *Bundle)

Update sets a new bundle as the bundle source and calls any registered callbacks

func (*BundleSource) ValidateNew 

func (bs *BundleSource) ValidateNew(resources Resources) error
