Constructor Detail

ControlAnalyticVectorField

public ControlAnalyticVectorField()
Method Detail

getPropertyList

public java.util.List<java.lang.String> getPropertyList()
Description copied from class: ControlElement
Returns the list of all properties that can be set for this ControlElement. Subclasses that add properties should implement this. Order is crucial here: Both for the presentation in an editor (f.i. ViewElement) and for the setValue() method.

Overrides:
getPropertyList in class ControlVectorField

getPropertyCommonName

public java.lang.String getPropertyCommonName(java.lang.String _property)
Description copied from class: ControlElement
This is used by Ejs to obtain an alias for the property name in order to search for this alias in a common file of easily translatable entries used in the tables of properties for an element.

Overrides:
getPropertyCommonName in class ControlElement
Parameters:
_property - String
Returns:
String

getPropertyInfo

public java.lang.String getPropertyInfo(java.lang.String _property)
Description copied from class: ControlElement
Returns information about a given property. Subclasses that add properties should implement this. Order in the implementation is irrelevant.
  • The first keyword is ALWAYS the type. If more than one type is accepted, they are separated by | (do NOT use spaces!)
  • The keyword CONSTANT applies to properties that can not be changed using the setValue() methods
  • The keyword VARIABLE_EXPECTED is used when a String could be accepted, but a variable has priority. In this case, a String requires using inverted commas or quotes
  • The keyword NotTrimmed specifies that leading or trailing spaces must be respected when present. This is useful for labels or titles, for instance
  • The keywords PREVIOUS and POSTPROCESS indicate that, when setting several properties at once (using setProperties()) the property must be process before, resp. after, the others

    Overrides:
    getPropertyInfo in class ControlVectorField

  • setValue

    public void setValue(int _index,
                         Value _value)
    Description copied from class: ControlElement
    Sets the value of the registered variables. Subclasses with internal values should extend this Order is crucial here: it must match exactly that of the getPropertyList() method.

    Overrides:
    setValue in class ControlVectorField

    setDefaultValue

    public void setDefaultValue(int _index)
    Overrides:
    setDefaultValue in class ControlVectorField

    getDefaultValueString

    public java.lang.String getDefaultValueString(int _index)
    Overrides:
    getDefaultValueString in class ControlVectorField

    getValue

    public Value getValue(int _index)
    Description copied from class: ControlElement
    Gets the value of any internal variable. Subclasses with internal values should extend this

    Overrides:
    getValue in class ControlVectorField
    Returns:
    Value _value The object holding the value for the variable.

    preupdate

    public void preupdate()
    Specified by:
    preupdate in interface NeedsPreUpdate
    Overrides:
    preupdate in class ControlVectorField
