LabelingInfo class final

An object that defines the text, appearance and position of labels for features for a given scale range.

A LabelingInfo describes a class of labels.

Each LabelingInfo specifies:

Which features are covered by the definition, by applying the LabelingInfo.where SQL constraint
What text should be displayed, based on the individual feature's attributes and the LabelingInfo.labelExpression formula
How the text should appear, using the LabelingInfo.symbol
Where the text should appear, with respect to its feature, using the LabelingInfo.labelPlacement

LabelingInfo describes a very limited subset of the LabelDefinition properties.
