/**

* When sending values to or receiving values from a [[Contract]], the

|
* data is generally encoded using the [ABI standard](solc-abi-standard).

|
|
* The AbiCoder provides a utility to encode values to ABI data and
|
|
* decode values from ABI data.
|
|
*
|
|
* Most of the time, developers should favour the [[Contract]] class,
|
|
* which further abstracts a lot of the finer details of ABI data.
