com.android.tools.lint.checks
Class MathDetector

java.lang.Object
  com.android.tools.lint.detector.api.Detector
      com.android.tools.lint.checks.MathDetector

All Implemented Interfaces:

com.android.tools.lint.detector.api.Detector.ClassScanner

public class MathDetector
extends com.android.tools.lint.detector.api.Detector
implements com.android.tools.lint.detector.api.Detector.ClassScanner

Looks for usages of Math methods which can be replaced with android.util.FloatMath methods to avoid casting.
