Class CoverageFinalizeAsmGenerator

java.lang.Object

org.ek9lang.compiler.backend.jvm.AbstractAsmGenerator

org.ek9lang.compiler.backend.jvm.CoverageFinalizeAsmGenerator

All Implemented Interfaces:

Consumer<CoverageFinalizeInstr>, org.objectweb.asm.Opcodes

final class CoverageFinalizeAsmGenerator
extends AbstractAsmGenerator
implements Consumer<CoverageFinalizeInstr>, org.objectweb.asm.Opcodes

Specialized ASM generator for CoverageFinalizeInstr processing.

Generates bytecode to finalize coverage data collection by calling CoverageRuntime.finaliseCoverage(outputPath) which writes probe data to files for post-execution analysis.

Generated bytecode pattern (2 instructions):

LDC outputPath                              (String constant, e.g., ".ek9")
INVOKESTATIC CoverageRuntime.finaliseCoverage(Ljava/lang/String;)V

This instruction should be emitted at the end of a program's main method to ensure coverage data is persisted before the JVM exits.
