_property: contractFactory.attach(address) => [[Contract]]
|
|
|
|
Return an instance of a [[Contract]] attched to //address//. This is the
|
|
same as using the [Contract constructor](contract--creating) with
|
|
//address// and this the the //interface// and //signerOrProvider// passed
|
|
in when creating the ContractFactory.
|
|
|
|
_property: contractFactory.getDeployTransaction(...args) => [[UnsignedTransaction]]
|
|
|
|
Returns the unsigned transaction which would deploy this Contract with //args// passed
|
|
to the Contract's constructor.
|
|
|
|
_property: contractFactory.deploy(...args) => Promise<[[Contract]]>
|
|
|
|
Uses the signer to deploy the Contract with //args// passed into tgee constructor and
|
|
retruns a Contract which is attached to the address where this contract **will** be
|
|
deployed once the transction is mined.
|
|
|
|
The transction can be found at ``contract.deployTransaction``, and no interactions
|
|
should be made until the transaction is mined.
