BaseRewardPool

The BaseRewardPool.sol contract is used as the main reward contract for all LP pools.
//sample convex reward contracts interface
interface IConvexRewards{
    //get balance of an address
    function balanceOf(address _account) external returns(uint256);
    //withdraw to a convex tokenized deposit
    function withdraw(uint256 _amount, bool _claim) external returns(bool);
    //withdraw directly to curve LP token
    function withdrawAndUnwrap(uint256 _amount, bool _claim) external returns(bool);
    //claim rewards
    function getReward() external returns(bool);
    //stake a convex tokenized deposit
    function stake(uint256 _amount) external returns(bool);
    //stake a convex tokenized deposit for another address(transfering ownership)
    function stakeFor(address _account,uint256 _amount) external returns(bool);
}
Token Type of Reward
Use baseRewardPool.rewardToken() to determine what token is rewarded
Balance of an Account
Use baseRewardPool.balanceOf(address) to see how much an address has staked.
Total Staked Amount
Use baseRewardPool.totalSupply() to see how much is currently staked on the reward contract
Current Earned Rewards
Use baseRewardPool.earned(address) to see how much rewards an address will receive if they claim their rewards now.
Claim Rewards
Use baseRewardPool.getReward() or baseRewardPool.getReward( address, bool ) to claim rewards for your address or an arbitrary address.  The bool is an option to also claim extra incentive tokens (ex. snx) which is defaulted to true in the non-parametrized version. More information on extra rewards below.
Stake/Deposit Tokens
Use baseRewardPool.stake( amount ) to stake a given amount for your address
Use baseRewardPool.stakeAll() to stake all tokens for your address
Use baseRewardPool.stakeFor( address, amount ) to stake on behalf of another address (*This transfers ownership of the tokens!)
Unstake/Withdraw Tokens
Use baseRewardPool.withdraw( amount, bool ) to withdraw a specific amount. bool is to also claim while withdrawing
Use baseRewardPool.withdrawAll( bool ) to withdraw all tokens staked. bool is to also claim while withdrawing
Use baseRewardPool.withdrawAndUnwrap( amount, bool ) to withdraw a specific amount of tokens AND also unwrap the tokens back into the underlying LP tokens. bool is to also claim while withdrawing
Use baseRewardPool.withdrawAllAndUnwrap(bool claim) to withdraw all tokens AND also unwrap the tokens back into the underlying LP tokens. bool is to also claim while withdrawing
Extra Rewards
The BaseRewardPool has an array of child reward contracts called extraRewards.
You can query the number of extra rewards via baseRewardPool.extraRewardsLength().
This array holds a list of VirtualBalanceRewardPool contracts which are similar in nature to the base reward contract but without actual control of staked tokens.

This means that if a pool has CRV rewards as well as SNX rewards, the pool's main reward contract(BaseRewardPool) will distribute the CRV and the child contract(VirtualBalanceRewardPool) will distribute the SNX.
Other Information
The reward contract mechanics are that of popular synthetix style reward contract.
Some important parameters for determining things like APY could be:
duration: The reward contract cycle length
periodFinish: When the current cycle is planned to finish
rewardRate: How many tokens are distributed per second
