Class ClassFieldProbeArrayStrategy
java.lang.Object
org.jacoco.core.internal.instr.ClassFieldProbeArrayStrategy
- All Implemented Interfaces:
IProbeArrayStrategy
The strategy for regular classes adds a static field to hold the probe array
and a static initialization method requesting the probe array from the
runtime.

storeInstance
public int storeInstance(org.objectweb.asm.MethodVisitor mv, boolean clinit, int variable) Description copied from interface:IProbeArrayStrategy
Creates code that stores the probe array instance in the given variable.- Specified by:
storeInstance
in interfaceIProbeArrayStrategy
- Parameters:
mv
- visitor to create codeclinit
- true in case of<clinit>
methodvariable
- variable index to store probe array to- Returns:
- maximum stack size required by the generated code
-
addMembers
public void addMembers(org.objectweb.asm.ClassVisitor cv, int probeCount) Description copied from interface:IProbeArrayStrategy
Adds additional class members required by this strategy. This method is called after all original members of the class has been processed.- Specified by:
addMembers
in interfaceIProbeArrayStrategy
- Parameters:
cv
- visitor to create fields and methodsprobeCount
- total number of probes required for this class
-
createDataField
private void createDataField(org.objectweb.asm.ClassVisitor cv) -
createInitMethod
private void createInitMethod(org.objectweb.asm.ClassVisitor cv, int probeCount) -
genInitializeDataField
private int genInitializeDataField(org.objectweb.asm.MethodVisitor mv, int probeCount) Generates the byte code to initialize the static coverage data field within this class. The code will push the [Z data array on the operand stack.- Parameters:
mv
- generator to emit code to
