示例1: transformLetNode
import org.mozilla.javascript.ast.LetNode; //导入依赖的package包/类
private Node transformLetNode(LetNode node) {
pushScope(node);
try {
decompiler.addToken(Token.LET);
decompiler.addToken(Token.LP);
Node vars = transformVariableInitializers(node.getVariables());
decompiler.addToken(Token.RP);
node.addChildToBack(vars);
boolean letExpr = node.getType() == Token.LETEXPR;
if (node.getBody() != null) {
if (letExpr) {
decompiler.addName(" ");
} else {
decompiler.addEOL(Token.LC);
}
node.addChildToBack(transform(node.getBody()));
if (!letExpr) {
decompiler.addEOL(Token.RC);
}
}
return node;
} finally {
popScope();
}
}
示例2: transformVariables
import org.mozilla.javascript.ast.LetNode; //导入依赖的package包/类
private Node transformVariables(VariableDeclaration node) {
decompiler.addToken(node.getType());
transformVariableInitializers(node);
// Might be most robust to have parser record whether it was
// a variable declaration statement, possibly as a node property.
AstNode parent = node.getParent();
if (!(parent instanceof Loop)
&& !(parent instanceof LetNode)) {
decompiler.addEOL(Token.SEMI);
}
return node;
}
示例3: let
import org.mozilla.javascript.ast.LetNode; //导入依赖的package包/类
private AstNode let(boolean isStatement, int pos)
throws IOException
{

ExpressionStatement es =
new ExpressionStatement(pn, !insideFunction());
es.setLineno(pn.getLineno());
