Method Detail

createVariable

public static GUIVariable createVariable(IDecisionVariable variable,
                                         org.eclipse.swt.widgets.Composite parent,
                                         GUIConfiguration config,
                                         GUIVariable varParent)

Creates a new GUIVariable.

Parameters:

variable - The IDecisionVariable represented by this GUIVariable

parent - The controlling composite, needed for the creation of CellEditors

config - The GUIConfiguration holding this BasisGUIVariable

varParent - The parent GUIVariable holding this variable. Can be null if and only if this variable is a top level variable stored inside the configuration.

Returns:

A GUI representation of the IDecisionVariable

createVariable

public static GUIVariable createVariable(IDecisionVariable variable,
                                         org.eclipse.swt.widgets.Composite parent,
                                         GUIConfiguration config,
                                         GUIVariable varParent,
                                         java.util.List<IRangeRestriction> rangeRestrictors)

Creates a new GUIVariable.

Parameters:

variable - The IDecisionVariable represented by this GUIVariable

parent - The controlling composite, needed for the creation of CellEditors

config - The GUIConfiguration holding this BasisGUIVariable

varParent - The parent GUIVariable holding this variable. Can be null if and only if this variable is a top level variable stored inside the configuration.

rangeRestrictors - Optional list to restrict values of some GUIVariable, e.g., to restrict values of combo box based variables.

Returns:

A GUI representation of the IDecisionVariable

createComboItemArray

private static ComboboxGUIVariable.ComboItem[] createComboItemArray(IDecisionVariable variable,
                                                                    int length)

Creates the array for combobox items and pre-assigns the null value if required via DisplayNameProvider.enableNullValueInConfiguration(IDecisionVariable). The caller may utilize the result until length but not further.

Parameters:

variable - the variable to create the combo items for

length - the length of the array to be created (except for null value entries)

Returns:

the created array

makeUnique

private static <T> java.util.List<T> makeUnique(java.util.List<T> list)

Returns a list of unique elements taken from list.

Type Parameters:

T - the element type

Parameters:

list - the list to be processed

Returns:

the list of unique elements from list in sequence of list

createComboItems

public static ComboboxGUIVariable.ComboItem[] createComboItems(IDecisionVariable variable,
                                                               Reference reference)

Creates combo items for the given variable of type reference.

Parameters:

variable - the variable to be considered

reference - the (required) reference type of variable

Returns:

the combo items

createUpdatableCellEditors

public static final void createUpdatableCellEditors(boolean updatable)

Defines whether updatable cell editors shall be created if possible.

Parameters:

updatable - if true, updatable cell editors shall be created, false for usual ones

createUpdatableCellEditors

public static final boolean createUpdatableCellEditors()

Returns whether updatable cell editors shall be created if possible.

Returns:

true if updatable cell editors shall be created, false for usual ones
