public final class GlyphMetrics extends Object
Instances of this class represent glyph metrics.The hashCode() method in this class uses the values of the public fields to compute the hash value. When storing instances of the class in hashed collections, do not modify these fields after the object has been inserted.
Application code does not need to explicitly release the resources managed by each instance when those instances are no longer required, and thus no
dispose()
method is provided.- Since:
