Field Detail

logger

static final org.apache.log4j.Logger logger

cg

final org.apache.bcel.generic.ClassGen cg

sourceLineNumbers

final java.util.Set sourceLineNumbers

The set of "real" source line numbers that are present in this class. That is, those lines of Java source code that do not represent comments, or other syntax "fluff" (e.g., "} else {"), or those lines that have been ignored because they match the ignore regex.

methodNamesAndSignatures

final java.util.Set methodNamesAndSignatures

The set of method names concatenated with their signature.

methodLineNumbers

final java.util.Map methodLineNumbers

A mapping from method name and signature to the set of line numbers for that method.

methodConditionals

final java.util.Map methodConditionals

A mapping from method name and signature to the set of conditionals for that method.

Method Detail

addInstrumentation

void addInstrumentation(org.apache.bcel.classfile.Method method)

Add instrumentation to a method found in this class.

Parameters:

method - a method present in the class

addInstrumentation

void addInstrumentation(org.apache.bcel.classfile.Method[] methods)

Add instrument to all the supplied methods.

addInstrumentation

void addInstrumentation()

Add coverage instrumentation to the class. Once instrumented, the instrumented class is tagged with a marker interface @see HasBeenInstrumented to prevent it from being instrumented again.

getMethodLineNumbers

java.util.Map getMethodLineNumbers()

Returns:

a mapping from method name and signature to the set of line numbers for that method.

getMethodConditionals
