Atitit dsl对于数组的处理以及main函数的参数赋值

1.1. 词法解析..添加了[] 方括号的解析支持1

1.2. Ast建立.添加了数组参数的支持..使用了递归下降法..getparam use recurs desc meth... Get arrayParam ya use recdesc meth..2

1.3. Ast解析的支持4

1.1. 词法解析..添加了[] 方括号的解析支持

public List getTokensV3() {

code_char_arr = code.toCharArray();

for (char c : code_char_arr) {

// get next char,,then change stat

// jude cur char and cur stat...then if or not chage stat

if (c == '[' && !this.curStat.equals("strStart"))

{

this.curStat="sqBrkStart";

Token tk2=new Token("[").setType("spltr");

tokens.add(tk2);

this.curTokenTxt = "";

continue;

}

if (c == ']' && !this.curStat.equals("strStart"))

{

this.curStat="sqBrkEnd";

Token tk2=new Token("]").setType("spltr");

tokens.add(tk2);

this.curTokenTxt = "";

continue;

}

1.2. Ast建立.添加了数组参数的支持..使用了递归下降法..getparam use recurs desc meth... Get arrayParam ya use recdesc meth..

} catch (ClassNotFoundException e) {

}

mi.arguments=arrParamProcess(mi.arguments);

li.add((String) object);

}

return li.toArray(new String[ li.size()]);

}

return null;
