SimpleDateFormat.compile介绍

[英]Returns the compiled form of the given pattern. The syntax of the compiled pattern is: CompiledPattern: EntryList EntryList: Entry EntryList Entry Entry: TagField TagField data TagField: Tag Length TaggedData Tag: pattern_char_index TAG_QUOTE_CHARS Length: short_length long_length TaggedData: TAG_QUOTE_ASCII_CHAR ascii_char where short_length' is an 8-bit unsigned integer between 0 and 254.long_length' is a sequence of an 8-bit integer 255 and a 32-bit signed integer value which is split into upper and lower 16-bit fields in two char's. pattern_char_index' is an 8-bit integer between 0 and 18.ascii_char' is an 7-bit ASCII character value. `data' depends on its Tag value.

If Length is short_length, Tag and short_length are packed in a single char, as illustrated below.

char[0] = (Tag << 8) | short_length; If Length is long_length, Tag and 255 are packed in the first char and a 32-bit integer, as illustrated below. char[0] = (Tag << 8) | 255; char[1] = (char) (long_length >>> 16); char[2] = (char) (long_length & 0xffff);

If Tag is a pattern_char_index, its Length is the number of pattern characters. For example, if the given pattern is "yyyy", Tag is 1 and Length is 4, followed by no data.

If Tag is TAG_QUOTE_CHARS, its Length is the number of char's following the TagField. For example, if the given pattern is "'o''clock'", Length is 7 followed by a char sequence of o&nbs;'&nbs;c&nbs;l&nbs;o&nbs;c&nbs;k.

TAG_QUOTE_ASCII_CHAR is a special tag and has an ASCII character in place of Length. For example, if the given pattern is "'o'", the TaggedData entry is ((TAG_QUOTE_ASCII_CHAR&nbs;<.
[中]返回给定模式的编译形式。编译模式的语法是：CompiledPattern:EntryList EntryList:Entry EntryList Entry:TagField TagField data TagField:Tag Length TaggedData:pattern\u char\u index Tag\u QUOTE\u CHARS Length:short\u Length long\u Length TaggedData:Tag\u QUOTE\u ASCII\u char ASCII\u char其中'short\u Length'是0到254之间的8位无符号整数“long_length”是一个8位整数255和一个32位带符号整数值的序列，该值在两个字符中分为上下16位字段。“pattern_char_index”是一个介于0和18之间的8位整数ascii_char'是一个7位ascii字符值“数据”取决于其标记值。 如果Length是short_Length，则将标记和short_Length打包在一个字符中，如下所示。 字符[0]=（标记<<8）|短|长度；如果Length是long_Length，则Tag和255被压缩在第一个字符和一个32位整数中，如下所示。字符[0]=（标记<8）| 255；字符[1]=（字符）（长长度>>>16）；char[2]=（char）（long_length&0xffff）； 如果标记是模式字符索引，则其长度为模式字符数。例如，如果给定的模式为“yyy”，则标记为1，长度为4，后跟无数据。 如果标记是Tag_QUOTE_CHARS，则其长度是标记字段后面的字符数。例如，如果给定的模式是“o”“clock”，则长度为7，后跟字符序列o&nbs;'&nbs;c&nbs;l&nbs;o&nbs;c&nbs;k。 TAG_QUOTE_ASCII_CHAR是一个特殊的标记，用ASCII字符代替长度。例如，如果给定的模式是“o”，则TaggedData条目是((TAG_QUOTE_ASCII_CHAR&nbs;<. `
