Label

function selector

Description

A function selector can be represented either by a canonical text form of the function signature (e.g. `exampleFunction(bytes32)`) or by its bytes form (e.g. `0xfc13a76a`). The latter is used by the EVM to call a certain function in a contract. It is created by taking the first 4 bytes of the keccac hash of the canonical text form of the signature.

Usage

Instances of :FunctionSelector can have the following properties:

PROPERTY	TYPE	DESCRIPTION	RANGE
From class :FunctionSelector
:byteSignature	owl:DatatypeProperty	A function can be identified by its byte signature. It is generated from the canonical signature. For example the Function `bar(uint32 x, bool y)` returns `(bool r)` has the canonical signature `bar(uint32,bool)`. The first 4 bytes of the Keccac 256 hash of this forms the byte signature of the function, in the example that would be `0xcdcd77c0`.	xsd:hexBinary
:canonicalSignature	owl:DatatypeProperty	The signature of the function in the canonical form which is used to create the functionSelector. Example: `bar(uint32,bool)`	xsd:string
