Functions

• allowance

  function allowance(address _tokenHolder, address _spender) public view returns (uint)

  Parameters:_tokenHolder - address_spender - addressReturns:The amount of tokens allowed to be spent by _spender from _tokenHolder.

• approve

  function approve(address _spender, uint _amount) public returns (bool)

  Msg.sender can approve another address to transferFrom(...) tokens from msg.senders address.Parameters:_spender - Approved address that can transferFrom(...) tokens._amount - Amount that _spender can use.Returns:bool

• approveAndCall

  function approveAndCall(address _spender, uint _amount, bytes _data) public returns (bool)

  Msg.sender can ping a contract that the contract has been approved to spend tokens on msg.senders behalf.Parameters:_spender - Contract address that can spend tokens._amount - Amount of tokens that the contract can spend._data - Arbitrary bytes value passed to contract.Returns:bool

• balanceOf

  function balanceOf(address _tokenHolder) public view returns (uint)

  Parameters:_tokenHolder - addressReturns:Token balance of token holder address.

• burn

  function burn(uint _amount) public returns (bool)

  Burns _amount of tokens from total supply and msg.senders balance.Parameters:_amount - Amount of tokens.Returns:bool

• burnFrom

  function burnFrom(address _from, uint _amount) public returns (bool)

  Burns _amount of tokens from total supply and _from balance if msg.sender has been approved.Parameters:_from - Address that tokens will be burnt from if msg.sender has been approved._amount - Amount of tokens that will be burnt _from address.Returns:bool

• fallback

  function (uint _initialAmount, string _tokenName, uint8 _decimalUnits, string _tokenSymbol) public

  Returns:The amount of tokens released.

• transfer

  function transfer(address _to, uint _amount) public returns (bool)

  Transfers tokens from msg.sender, to the _to address for the _amount parameter.Parameters:_to - Address to transfer the tokens too._amount - Amount of tokens to transfer.Returns:bool

• transferFrom

  function transferFrom(address _from, address _to, uint _amount) public returns (bool)
