方法详细资料

matches

boolean matches()

Attempts to match the entire region against the pattern.

If the match succeeds then more information can be obtained via the start, end, and group methods.

返回:

true if, and only if, the entire region sequence matches this matcher's pattern

reset

RegexpMatcher reset()

Resets this matcher.

Resetting a matcher discards all of its explicit state information and sets its append position to zero. The matcher's region is set to the default region, which is its entire character sequence. The anchoring and transparency of this matcher's region boundaries are unaffected.

返回:

This matcher

find

boolean find()

Attempts to find the next subsequence of the input sequence that matches the pattern. 找到下一个匹配的子串

This method starts at the beginning of this matcher's region, or, if a previous invocation of the method was successful and the matcher has not since been reset, at the first character not matched by the previous match.

If the match succeeds then more information can be obtained via the start, end, and group methods.

返回:

true if, and only if, a subsequence of the input sequence matches this matcher's pattern

find

boolean find(int start)

Resets this matcher and then attempts to find the next subsequence of the input sequence that matches the pattern, starting at the specified index.

If the match succeeds then more information can be obtained via the start, end, and group methods, and subsequent invocations of the find() method will start at the first character not matched by this match.

参数:

start - the index to start searching for a match

返回:

true if, and only if, a subsequence of the input sequence starting at the given index matches this matcher's pattern

抛出:

IndexOutOfBoundsException - If start is less than zero or if start is greater than the length of the input sequence.

appendReplacement

RegexpMatcher appendReplacement(StringBuffer b,
                                String replacement)

对匹配到的部分，进行文本替换

参数:

b - 替换后存入的buffer

replacement - 替换物

返回:

匹配器

appendTail

void appendTail(StringBuffer b)

把原始文本中 剩余部分添加的 StringBuffer中

参数:

b -
