Class MethodCoverageCalculator

java.lang.Object
org.jacoco.core.internal.analysis.MethodCoverageCalculator
All Implemented Interfaces:
IFilterOutput
class MethodCoverageCalculator extends Object implements IFilterOutput
Calculates the filtered coverage of a single method. A instance of this class can be first used as IFilterOutput before the coverage result is calculated.

    • instructions

      private final Map<org.objectweb.asm.tree.AbstractInsnNode, Instruction> instructions

    • ignored

    • merged

      private final Map<org.objectweb.asm.tree.AbstractInsnNode, org.objectweb.asm.tree.AbstractInsnNode> merged
      Instructions that should be merged form disjoint sets. Coverage information from instructions of one set will be merged into representative instruction of set. Each such set is represented as a singly linked list: each element except one references another element from the same set, element without reference - is a representative of this set. This map stores reference (value) for elements of sets (key).
