说明:
特殊构造(非捕获)
(?:X) X,作为非捕获组
(?idmsux-idmsux) Nothing,但是将匹配标志由 on 转为 off
(?idmsux-idmsux:X) X,作为带有给定标志 on - off 的非捕获组
(?=X) X,通过零宽度的正 lookahead
(?!X) X,通过零宽度的负 lookahead
(?<=X) X,通过零宽度的正 lookbehind
(?<!X) X,通过零宽度的负 lookbehind
(?>X) X,作为独立的非捕获组
public static Pattern compile(String regex,int flags);
参数:
regex - 要编译的表达式。
flags - 匹配标志,可能包括 CASE_INSENSITIVE、MULTILINE、DOTALL、UNICODE_CASE 和 CANON_EQ 的位掩码。
Pattern中的定义如下:
- public static final int UNIX_LINES = 0x01;
- public static final int CASE_INSENSITIVE = 0x02;
- public static final int COMMENTS = 0x04;
- public static final int MULTILINE = 0x08;
- public static final int LITERAL = 0x10;
- public static final int DOTALL = 0x20;
- public static final int UNICODE_CASE = 0x40;
- public static final int CANON_EQ = 0x80;
public static final int UNIX_LINES = 0x01; public static final int CASE_INSENSITIVE = 0x02; public static final int COMMENTS = 0x04; public static final int MULTILINE = 0x08; public static final int LITERAL = 0x10; public static final int DOTALL = 0x20; public static final int UNICODE_CASE = 0x40; public static final int CANON_EQ = 0x80;
