An IlvAnchoredLabel
is a subclass of IlvGraphic
containing an IlvMapLabel
and a reference IlvGraphic
.
Constructor and Description |

IlvLabeledPointRenderer . |
IlvLabeledPointRenderer(IlvInputStream stream)
Reads an
IlvLabeledPointRenderer from the stream stream . |
IlvLabeledPointRenderer(String[] attributeNames,
String[] rejectedValues)
Constructs an
IlvLabeledPointRenderer with the name
of the attribute and a value. |
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 always 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.
|
void |
setRejectedValues(String[] rejectedValues)
Sets the arrays of values to be rejected from attribute values.
|
void |
setTextRenderingStyle(IlvMapTextRenderingStyle style)
Sets the text style for the
IlvAnchoredLabel s label. |
void |

with the name
of the attribute and a value.
If 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
