func (*Cache) InitializeLocalChaincodes ¶
InitializeLocalChaincodes should be called once after cache creation (timing doesn't matter, though already installed chaincodes will not be invokable until it it completes).

Instead, use the utility functions attached to the lifecycle Resources when needed.

CommitChaincodeDefinition takes a chaincode definition, checks that its sequence number is the next allowable sequence number, checks which organizations have approved the definition, and applies the definition to the public world state. It is the responsibility of the caller to check the approvals to determine if the result is valid (typically, this means checking that the peer's own org has approved the definition).
