Constructor & Destructor Documentation

◆ Processor() [1/2]

semf::esh::Processor::Processor	(	const LinkedList< Command > &	commands,
		Printer &	printer,
		char	lineBuffer[],
		size_t	lineBufferSize,
		char **	argvBuffer,
		size_t	argvBufferSize
	)

Constructor.

Parameters

commands	List of available commands.
printer	Printer for printing.
lineBuffer	Buffer containing the current command line.
lineBufferSize	Size of `lineBuffer` .
argvBuffer	Pointer array of char* for pointing to arguments. The upper bound for this buffer is `lineBufferSize` / 2. The lower bound is 1 (no command takes parameters).
argvBufferSize	Length of `argvBuffer` .

Member Function Documentation

◆ execLoadedCommand()

void semf::esh::Processor::execLoadedCommand ( )

Execute the currenty loaded command. Returns with no error if no command is loaded. Unloads the loaded command after execution.

Definition at line 56 of file processor.cpp.

Here is the caller graph for this function:

◆ loadCommand()

void semf::esh::Processor::loadCommand ( )

Load a command for execution according to the current command line.

Exceptions

LoadCommand_IsBusy If object is busy.

Definition at line 27 of file processor.cpp.

◆ SEMF_SIGNAL() [1/2]

semf::esh::Processor::SEMF_SIGNAL ( done )

Gets emitted after the loaded command was executed.

◆ SEMF_SIGNAL() [2/2]

semf::esh::Processor::SEMF_SIGNAL	(	error	,
		Error
	)

Gets emitted on errors.
