示例1: enterBlock
import jdk.nashorn.internal.ir.Block; //导入方法依赖的package包/类
@Override
public boolean enterBlock(final Block block) {
boolean cloned = false;
for(final Symbol symbol: block.getSymbols()) {
if(symbol.isBytecodeLocal()) {
if (getLocalVariableTypeOrNull(symbol) == null) {
if (!cloned) {
cloneOrNewLocalVariableTypes();
cloned = true;
}
localVariableTypes.put(symbol, LvarType.UNDEFINED);
}
// In case we're repeating analysis of a lexical scope (e.g. it's in a loop),
// make sure all symbols lexically scoped by the block become valid again.
invalidatedSymbols.remove(symbol);
}
}
return true;
