Function Documentation

◆ CreateChainParams()

std::unique_ptr<const CChainParams> CreateChainParams ( const ArgsManager args,
const std::string &  chain 
)

Creates and returns a std::unique_ptr<CChainParams> of the chosen chain.

Returns
a CChainParams* of the chosen chain.
Exceptions
astd::runtime_error if the chain is not supported.

Definition at line 528 of file chainparams.cpp.

◆ operator<<()

std::ostream& operator<< ( std::ostream &  o,
const AssumeutxoData aud 
)

Here is the call graph for this function:

◆ Params()

const CChainParams& Params ( )

Return the currently selected parameters.

This won't change after app startup, except for unit tests.

◆ SelectParams()

void SelectParams ( const std::string &  chain)

Sets the params returned by Params() to those for the given chain name.

Exceptions
std::runtime_errorwhen the chain is not supported.
