Method Detail

readConstraint

public IlvConstraint readConstraint(Element elem,
                                    IlvGanttDocumentReader.Context readContext)
                             throws IlvGanttReaderException

Reads an IlvGeneralConstraint from a given Element. This method does the following:

• Reads the given Element and gets the IDs of the from and to activities.
• Finds the from and to activity instances in the Gantt model.
• Creates and returns a new IlvGeneralConstraint. This function does not add the newly created constraint to the Gantt model.

Specified by:

readConstraint in interface IlvConstraintReader

Overrides:

readConstraint in class IlvSimpleConstraintReader

Parameters:

elem - The given element to read from.

readContext - The read context.

Returns:

The newly created constraint.

Throws:

IlvGanttReaderException - if an error occurs while reading the constraint.

createConstraint

protected IlvConstraint createConstraint(IlvActivity from,
                                         IlvActivity to,
                                         IlvConstraintType type)

Creates an IlvGeneralConstraint with the specified parameters. This method is called by readConstraint. If you want to create a customized constraint reader, you can override this method to create a customized constraint.

Overrides:

createConstraint in class IlvSimpleConstraintReader

Parameters:

from - The from activity for the constraint.

to - The to activity for the constraint.

type - The type of constraint.

Returns:

The newly created constraint.
