Method Detail

readConstraint

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

Reads an IlvSimpleConstraint 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 IlvSimpleConstraint. This function does not add the newly created constraint to the Gantt model.

Specified by:

readConstraint in interface IlvConstraintReader

Parameters:

elem - The given element to read from.

readContext - The read context.

Returns:

The newly created constraint.

Throws:

IlvGanttReaderException

GetConstraintType

public static IlvConstraintType GetConstraintType(String type)

Gets the constraint type from a string.

Parameters:

type - The String indicating the type of constraint. It must be one of the following: "Start-Start", "Start-End", "End-Start" or "End-End".

Returns:

The type of constraint.

createConstraint

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

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

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.
