PatternElementMatch (findbugs 3.0.1)

java.lang.Object
- edu.umd.cs.findbugs.ba.bcp.PatternElementMatch

```
public class PatternElementMatch
extends Object
```
PatternElementMatch represents matching a PatternElement against a single instruction. The "prev" field points to the previous PatternElementMatch. By building up sequences of PatternElementMatch objects in this way, we can implement nondeterministic matching without having to copy anything.

public PatternElementMatch(PatternElement patternElement,
                   org.apache.bcel.generic.InstructionHandle matchedInstruction,
                   BasicBlock basicBlock,

                   PatternElementMatch prev)
```
    Constructor.
    
    Parameters:
    patternElement - the PatternElement being matched
    matchedInstruction - the instruction which matched the PatternElement
    basicBlock - the basic block containing the matched instruction
    matchCount - the index (starting at zero) of the instructions matching the PatternElement; multiple instructions can match the same PatternElement
    prev - the previous PatternElementMatch
