Function Documentation

abi_def_from_file()

chain::abi_def sysio::trace_api::configuration_utils::abi_def_from_file	(	const std::string &	file_name,
		const fc::path &	data_dir )

Given a path (absolute or relative) to a file that contains a JSON-encoded ABI, return the parsed ABI

Parameters

file_name	- a path to the ABI
data_dir	- the base path for relative file_name values

Returns

the ABI implied

Exceptions

json_parse_exception

if the JSON is malformed
