Application Binary Interface

An Application Binary Interface (ABI) is a collection of Fragments which specify how to interact with various components of a Contract.

An Interface helps organize Fragments by type as well as provides the functionality required to encode, decode and work with each component.

Most developers will not require this low-level access to encoding and decoding the binary data on the network and will most likely use a Contract which provides a more convenient interface. Some framework, tool developers or developers using advanced techniques may find these classes and utilities useful.
