Member Function Documentation

QScxmlError::QScxmlError()

Creates a new invalid SCXML error.

QScxmlError::QScxmlError(const QString &fileName, int line, int column, const QString &description)

Creates a new valid SCXML error that contains the error message, description, as well as the fileName, line, and column where the error occurred.

QScxmlError::QScxmlError(const QScxmlError &other)

Constructs a copy of other.

QScxmlError::~QScxmlError()

Destroys the SCXML error.

int QScxmlError::column() const

Returns the column in which the error occurred.

Note: Getter function for property column.

QString QScxmlError::description() const

Returns the error message.

Note: Getter function for property description.

QString QScxmlError::fileName() const

Returns the name of the file in which the error occurred.

Note: Getter function for property fileName.

bool QScxmlError::isValid() const

Returns true if the error is valid, false otherwise. An invalid error can only be created by calling the default constructor or by assigning an invalid error.

Note: Getter function for property valid.

int QScxmlError::line() const

Returns the line on which the error occurred.

Note: Getter function for property line.

QString QScxmlError::toString() const

This convenience method converts an error to a string. Returns the error message formatted as: "filename:line:column: error: description"

QScxmlError &QScxmlError::operator=(const QScxmlError &other)

Assigns other to this SCXML error and returns a reference to this SCXML error.
