Detailed Description

Definition at line 150 of file util.h.

Member Typedef Documentation

◆ Default

Default constant value.

Definition at line 197 of file util.h.

◆ DefaultHint

using RPCArg::DefaultHint = std::string

Hint for default value.

Definition at line 195 of file util.h.

◆ Fallback

Definition at line 198 of file util.h.

Member Enumeration Documentation

◆ Optional

Enumerator
NO 

Required arg.

OMITTED 

The arg is optional for one of two reasons:

Optional arg that is a named argument and has a default value of null.

Optional argument with default value omitted because they are implicitly clear. That is, elements in an array may not exist by default. When possible, the default value should be specified.

OMITTED_NAMED_ARG 

Definition at line 177 of file util.h.

◆ Type

Enumerator
OBJ 
ARR 
STR 
NUM 
BOOL 
OBJ_NAMED_PARAMS 

Special type that behaves almost exactly like OBJ, defining an options object with a list of pre-defined keys.

The only difference between OBJ and OBJ_NAMED_PARAMS is that OBJ_NAMED_PARMS also allows the keys to be passed as top-level named parameters, as a more convenient way to pass options to the RPC method without nesting them.

OBJ_USER_KEYS 

Special type where the user must set the keys e.g.

to define multiple addresses; as opposed to e.g. an options object where the keys are predefined

AMOUNT 

Special type representing a floating point amount (can be either NUM or STR)

STR_HEX 

Special type that is a STR with only hex chars.

RANGE 

Special type that is a NUM or [NUM,NUM].

Member Function Documentation

◆ GetFirstName()

std::string RPCArg::GetFirstName ( ) const

Return the first of all aliases.

Definition at line 834 of file util.cpp.

Here is the caller graph for this function:
