Overview

Package gwc contains the simplified mobile APIs to go-ethereum.

The scope of this package is *not* to allow writing a custom Gquantumchain client with pieces plucked from go-ethereum, rather to allow writing native dapps on mobile platforms. Keep this in mind when using or extending this package!

API limitations

Since gomobile cannot bridge arbitrary types between Go and Android/iOS, the exposed APIs need to be manually wrapped into simplified types, with custom constructors and getters/setters to ensure that they can be meaningfully used from Java/ObjC too.

With this in mind, please try to limit the scope of this package and only add essentials without which mobile support cannot work, especially since manually syncing the code will be unwieldy otherwise. In the long term we might consider writing custom library generators, but those are out of scope now.

Content wise each file in this package corresponds to an entire Go package from the go-ethereum repository. Please adhere to this scoping to prevent this package getting unmaintainable.

Wrapping guidelines:

Every type that is to be exposed should be wrapped into its own plain struct, which internally contains a single field: the original go-ethereum version. This is needed because gomobile cannot expose named types for now.

Whenever a method argument or a return type is a custom struct, the pointer variant should always be used as value types crossing over between language boundaries might have strange behaviors.

Slices of types should be converted into a single multiplicative type wrapping a go slice with the methods `Size`, `Get` and `Set`. Further slice operations should not be provided to limit the remote code complexity. Arrays should be avoided as much as possible since they complicate bounds checking.

If a method has multiple return values (e.g. some return + an error), those are generated as output arguments in ObjC. To avoid weird generated names like ret_0 for them, please always assign names to output variables if tuples.

Note, a panic *cannot* cross over language boundaries, instead will result in an undebuggable SEGFAULT in the process. For error handling only ever use error returns, which may be the only or the second return.

There are two basic forms of node designators

  • incomplete nodes, which only have the public key (node ID)
  • complete nodes, which contain the public key and IP/Port information

For incomplete nodes, the designator must look like one of these 

enode://<hex node id>
<hex node id>

For complete nodes, the node ID is encoded in the username portion of the URL, separated from the host by an @ sign. The hostname can only be given as an IP address, DNS domain names are not allowed. The port in the host name section is the TCP listening port. If the TCP and UDP (discovery) ports differ, the UDP port is specified as query parameter "discport".

In the following example, the node URL describes a node with IP address 10.3.58.6, TCP listening port 30304 and UDP discovery port 30301.
