Functions

func BuildConfigEndpointFromOptions 

func BuildConfigEndpointFromOptions(opts ...interface{}) (fab.EndpointConfig, error)

BuildConfigEndpointFromOptions will return an EndpointConfig instance pre-built with Optional interfaces provided in fabsdk's WithEndpointConfig(opts...) call

func ConfigFromBackend 

func ConfigFromBackend(coreBackend ...core.ConfigBackend) (fab.EndpointConfig, error)

ConfigFromBackend returns endpoint config implementation for given backend

func IsEndpointConfigFullyOverridden 

func IsEndpointConfigFullyOverridden(c *EndpointConfigOptions) bool

IsEndpointConfigFullyOverridden will return true if all of the argument's sub interfaces is not nil (ie EndpointConfig interface not fully overridden)

func UpdateMissingOptsWithDefaultConfig 

func UpdateMissingOptsWithDefaultConfig(c *EndpointConfigOptions, d fab.EndpointConfig) fab.EndpointConfig

UpdateMissingOptsWithDefaultConfig will verify if any functions of the EndpointConfig were not updated with fabsdk's WithConfigEndpoint(opts...) call, then use default EndpointConfig interface for these functions instead
