Constructor & Destructor Documentation

◆ StringLineMultiField()

ml::StringLineMultiField::StringLineMultiField ( const std::string & name = "" )

Constructor. See constructor of MultiField for documentation.

Member Function Documentation

◆ getStringValue() [1/2]

std::string ml::StringLineMultiField::getStringValue ( ) const

overridevirtual

Same as getStringValue(StringLineMultiField::DefaultLineSeparator).

Reimplemented from ml::MultiField< std::string >.

◆ getStringValue() [2/2]

std::string ml::StringLineMultiField::getStringValue ( const std::string & sep ) const

Returns a string containing the concatenation of all values from the internal vector separated by the StringLineMultiField::DefaultLineSeparator.

After the last element sep is not appended. Note that using other values than StringLineMultiField::DefaultLineSeparator for sep will cause asymmetric conversion from/to setString(value) and getString() methods. So take care and make use of removeChar('
') and removeChar('\r') if necessary.

◆ ML_CLASS_HEADER()

ml::StringLineMultiField::ML_CLASS_HEADER ( StringLineMultiField )

Macro to implement the interface for the Runtime Type System and for the initialization of this class.

See mlRuntimeSubClass.h for more information.

◆ removeElements()

void ml::StringLineMultiField::removeElements ( const std::string & str = std::string() )

Removes all entries equal to str; default is an empty string to remove all empty entries.

◆ removeSubString()

void ml::StringLineMultiField::removeSubString ( const std::string & str )

Removes the character sequence str from each string element of the internal vector.

◆ setStringValue() [1/2]

void ml::StringLineMultiField::setStringValue ( const std::string & value )

overridevirtual

Same as setStringValue(const std::string &value, char sep) using the "\n" as value for sep; occurrences of "\r\n" (Windows convention) or just '\r' (Mac convention) are converted to '
' first.

Reimplemented from ml::MultiField< std::string >.

◆ setStringValue() [2/2]

void ml::StringLineMultiField::setStringValue	(	const std::string &	value,
		const std::string &	sep
	)

Subdivides value at all positions of sep and stores all values in the internal vector.

Note that '
' characters in value if sep differs from DefaultLineSeparator will not be not used as separator. This will cause asymmetric behaviour from/to the default setString(value) and getString() methods when those are used for field persistence. So take care when using non line feed characters and make use of removeSubString("\n") and/or removeSubString("\r") if necessary.

Parameters

value	The string to be subdivided.
sep	The character sequence used to separate string segments.

Member Data Documentation

◆ DefaultLineSeparator

const std::string ml::StringLineMultiField::DefaultLineSeparator

static

The default line separator used for line endings when converting the internal string vector to a string with the default getString() or operator>>.

"\r\n" on windows and "\n" on non windows systems.
