java - JJTree の「IN」と「CONTAINS」の実現

Question

この質問は私を夢中にさせます。そのような式を解析できる生成されたクラスがあります。

「is_container AND custom_application_name IN ("myasp.com","fraworks")」

そしてそれは次のように評価されます：

'is_container AND ((application_name CONTAINS "fraworks" IGNORECASE) OR (application_name CONTAINS "myasp.com" IGNORECASE))'

しかし、私はそのようにする必要があります:

'is_container AND ((application_name IS "fraworks" IGNORECASE) OR (application_name IS "myasp.com" IGNORECASE))'

問題は、「IN」リテラルを処理するときに jjTree がバリアントの配列 (「myasp.com」、「fraworks」) を反復処理し、「CONTAINS」を使用する場所を見つけて、そこに「IS」を配置する方法です。

これを説明する私の.jjtファイルの部分：

式全体を解析する関数

void DiscreteRangeExpression()#DiscreteRangeExpression(true):
{
Token t=null;
}
{
    ((Variable() TerminalIn() SetLiteral())|(SetLiteral() TerminalIn() Variable()))
//Variable() TerminalIn() SetLiteral()
(
    TerminalIgnorecase()
{
    jjtThis.setIgnorecase(true);
}
)? 
{
    jjtThis.setOccurType(OCCURSANY);
} 
(
    <ALL>
{
    jjtThis.setOccurType(OCCURSALL);
}
    |
    <ANY> 
    |
    (
            <OCCURS> 
            t=<INTEGER_LITERAL>
{
    jjtThis.setOccurType(OCCURSEQUAL);
    jjtThis.setOccurNum(t.image);
} 
        (
                <PLUS>
{
    jjtThis.setOccurType(OCCURSMORE);
}
                |
                <MINUS>
{
    jjtThis.setOccurType(OCCURSLESS);
}
        )?
    )
)?
}

ターミナル "IN":

void TerminalIn() : 
{}
{
    <IN>
}

予約語:

}
