Field Documentation

const CommandStatus* CVC4::Command::d_commandStatus

protectedinherited

This field contains a command status if the command has been invoked, or NULL if it has not.

This field is either a dynamically-allocated pointer, or it's a pointer to the singleton CommandSuccess instance. Doing so is somewhat asymmetric, but it avoids the need to dynamically allocate memory in the common case of a successful command.

Definition at line 194 of file command.h.

bool CVC4::Command::d_muted

protectedinherited

True if this command is "muted"—i.e., don't print "success" on successful execution.

Definition at line 200 of file command.h.

std::string CVC4::EmptyCommand::d_name
