Support contains functions that the endorser requires to execute its tasks

type SupportImpl

type SupportImpl struct{}

SupportImpl provides an implementation of the endorser.Support interface issuing calls to various static methods of the peer

func (*SupportImpl) CheckACL

func (s *SupportImpl) CheckACL(signedProp *pb.SignedProposal, chdr *common.ChannelHeader, shdr *common.SignatureHeader, hdrext *pb.ChaincodeHeaderExtension) error
