↓ 105 callersMethodInsert

Insert is used to add or update an object into the given table. When updating an object, the obj provided should be a copy rather than a value update

↓ 80 callersMethodTxn

Txn is used to start a new transaction in either read or write mode. There can only be a single concurrent writer, but any number of readers.

↓ 70 callersMethodNext

Next returns the next result from the iterator. If there are no more results nil is returned.

↓ 61 callersMethodFirst

First is used to return the first matching object for the given constraints on the index. Note that all values read in the transaction form a consist

↓ 36 callersMethodCommit

Commit is used to finalize this transaction. This is a noop for read transactions, already aborted or committed transactions.

Delete is used to delete a single object from the given table. This object must already exist in the table.

Watch blocks until one of the channels in the watch set is closed, or timeoutCh sends a value. Returns true if timeoutCh is what caused Watch to unblo

↓ 10 callersMethodAdd

Add appends a watchCh to the WatchSet if non-nil.
