IlvLabeledAreaRenderer(IlvInputStream stream)
Reads an
IlvLabeledAreaRenderer from the stream stream |
IlvLabeledAreaRenderer(String[] attributeNames,
String[] rejectedValues)
Constructs a
IlvLabeledAreaRenderer with the list of attributes names
of interest and the attributes values to discard. |
Modifier and Type | Method and Description |
---|---|
String[] |
getAttributeNames()
Retrieves the array of attribute names.
|
String |
getName(IlvMapFeature feature)
Retrieves a name in the attributes of the feature
that matches the criteria defined in the constructor.
|
String[] |
getRejectedValues()
Retrieves the arrays of values to be rejected from attribute values.
|
IlvMapTextRenderingStyle |
getTextRenderingStyle()
Retrieves the test rendering style for the
IlvAnchoredLabel s label. |
boolean |
isAlwaysProducingGraphic()
Tells if the renderer is alway producing graphic even if there
is no matching name or value in the attributes.
|
IlvGraphic |
makeGraphic(IlvMapFeature feature,
IlvCoordinateTransformation tr)
Makes the graphic accordingly to the rule described
in the constructor documentation.
|
void |
setAlwaysProducingGraphic(boolean produce)
Tells the renderer if it should produce an
IlvGraphic
even if there is no matching name or value in the attributes. |
void |
setAttributeNames(String[] attributeNames)
Sets the attributes whose names are candidate to be displayed by the label.

with the list of attributes names
of interest and the attributes values to discard.
If the an attribute whose name is contained in the attributeNames
array is found, and if the value of this attribute is different from a
value found in the rejectedValues
array, an IlvAnchoredLabel
with a label will be made.
Otherwise, depending on the AlwaysProducingGraphic flag, a null graphic or a IlvAnchoredLabel
with only a reference graphic will be produced.attributeNames
