Method Detail

touchById

public static void touchById(org.jetbrains.coverage.org.objectweb.asm.MethodVisitor mv,
                             int id,
                             boolean calculateHits)

Util method for touching coverage counter which is stored in an array. An array must be already loaded on stack. This method has different strategies basing on calculateHits option:
when option is true, int array is expected and array counter is incremented,
otherwise boolean array is expected and the value is just set to true.

Parameters:

mv - current method visitor

id - index of a hit in the array

getBytecodeVersion

public static int getBytecodeVersion(org.jetbrains.coverage.org.objectweb.asm.ClassReader cr)

isCondyEnabled

public static boolean isCondyEnabled(org.jetbrains.coverage.org.objectweb.asm.ClassReader cr)

pushInt

public static void pushInt(org.jetbrains.coverage.org.objectweb.asm.MethodVisitor mv,
                           int value)

push

public static void push(org.jetbrains.coverage.org.objectweb.asm.MethodVisitor mv,
                        java.lang.Object o)

Push value on stack.

Parameters:

o - value to push must be primitive or String

getParentClassIfIsInner

public static java.lang.String getParentClassIfIsInner(org.jetbrains.coverage.org.objectweb.asm.ClassReader cr)

Get the name of the parent class if the given class is an inner class.

Parameters:

cr - the ClassReader that reads the class file

Returns:

the name of the parent class if the given class is an inner class, null otherwise

getClassAnnotations

public static java.util.List<java.lang.String> getClassAnnotations(org.jetbrains.coverage.org.objectweb.asm.ClassReader cr)

Get the annotations of a class in the bytecode.

Parameters:

cr - the ClassReader that reads the class file

Returns:

a list of annotations for the given class

getOuterClass

public static InstrumentationUtils.MethodDescriptor getOuterClass(org.jetbrains.coverage.org.objectweb.asm.ClassReader cr)

Get the outer class of a class in the bytecode.

Parameters:

cr - the ClassReader that reads the class file

Returns:

the outer class of the given class, or null if there is no outer class
