public interface SubstringMatcher
This interface is implemented by a collation that is capable of supporting
the XPath functions that require matching of a substring: namely contains(),
starts-with, ends-with, substring-before, and substring-after. For sorting
and comparing strings, a collation needs to implement only the StringCollator
interface; for matching of substrings, it must also implement this interface.
Method Summary | |
---|---|
boolean |
contains(String s1,
String s2)
Test whether one string contains another, according to the rules of the XPath contains() function |
boolean |
endsWith(String s1,
String s2)
Test whether one string ends with another, according to the rules of the XPath ends-with() function |
boolean |
startsWith(String s1,
String s2)
Test whether one string starts with another, according to the rules of the XPath starts-with() function |
String |
substringAfter(String s1,
String s2)
Return the part of a string after a given substring, according to the rules of the XPath substring-after() function |
String |
substringBefore(String s1,
String s2)
Return the part of a string before a given substring, according to the rules of the XPath substring-before() function |
