◆ addMissingVectorComponent()

string addMissingVectorComponent	(	const string &	sVectorComponent,
		const string &	sLeft,
		const string &	sRight,
		bool	bAddStrings
	)

This function determines the value of missing vector components (i.e. a vector contains not enough elements compared to the others used in the current expression) by applying a simple heuristic to the expression. It will either insert "1", "0" or an empty string in string expressions.

Parameters

sVectorComponent	const string&
sLeft	const string&
sRight	const string&
bAddStrings	bool

Returns: string

◆ convertVectorToExpression()

void convertVectorToExpression	(	string &	sLine,
		const Settings &	_option
	)

This function replaces vector expressions with their corresponding multi- expression equation.

Parameters

sLine	string&
_option	const Settings&

Returns: void

It is used quite extensively, however, it might not be necessary everywhere, because the parser can cope with the vector syntax now.

◆ evaluateIndices()

bool evaluateIndices	(	const string &	sCache,
		Indices &	_idx,
		MemoryManager &	_data
	)

This function will evaluate the passed indices, so that they match the dimensions of the passed cache, if they are defined as open ended.

Parameters

sCache	const string&
_idx	Indices&
_data	Datafile&

Returns: bool

This function evaluates the "target=TABLE()" expression and creates the target table, if needed.

Parameters

sCmd	string&
sDefaultTarget	const string&
_idx	Indices&
_parser	Parser&
_data	Datafile&
_option	const Settings&

Returns: string

If this option is not found, the function will create a default target cache.
