// ResolveNameConflict returns the next available name for a given thing.
|
|
// This helper can be used for lots of purposes:
|
|
//
|
|
// - In solidity function overloading is supported, this function can fix
|
|
// the name conflicts of overloaded functions.
|
|
// - In golang binding generation, the parameter(in function, event, error,
|
|
// and struct definition) name will be converted to camelcase style which
|
|
// may eventually lead to name conflicts.
|
|
//
|
|
// Name conflicts are mostly resolved by adding number suffix.
|
|
// e.g. if the abi contains Methods send, send1
|
|
// ResolveNameConflict would return send2 for input send.
