|

|
|
// - 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" and "send1", ResolveNameConflict would return "send2" for input "send".
