public class RuleBasedSubstringMatcher extends SimpleCollation implements SubstringMatcher
This class wraps a RuleBasedCollator to provide a SubstringMatcher. This users the facilities offered by the RuleBasedCollator to implement the XPath functions contains(), starts-with(), ends-with(), substring-before(), and substring-after().

Method Detail
-
contains
public boolean contains(UnicodeString s1, UnicodeString s2)
Test whether one string contains another, according to the rules of the XPath contains() function- Specified by:
contains
in interfaceSubstringMatcher
- Parameters:
s1
- the containing strings2
- the contained string- Returns:
- true iff s1 contains s2
-
endsWith
public boolean endsWith(UnicodeString s1, UnicodeString s2)
Test whether one string ends with another, according to the rules of the XPath ends-with() function- Specified by:
endsWith
in interfaceSubstringMatcher
- Parameters:
s1
- the containing strings2
- the contained string- Returns:
- true iff s1 ends with s2
-
startsWith
public boolean startsWith(UnicodeString s1, UnicodeString s2)
Test whether one string starts with another, according to the rules of the XPath starts-with() function- Specified by:
startsWith
in interfaceSubstringMatcher
- Parameters:
s1
- the containing strings2
- the contained string- Returns:
- true iff s1 starts with s2
-
substringAfter
public UnicodeString substringAfter(UnicodeString s1, UnicodeString s2)
Return the part of a string after a given substring, according to the rules of the XPath substring-after() function- Specified by:
substringAfter
in interfaceSubstringMatcher
- Parameters:
s1
- the containing strings2
- the contained string- Returns:
- the part of s1 that follows the first occurrence of s2
-
substringBefore
public UnicodeString substringBefore(UnicodeString s1, UnicodeString s2)
Return the part of a string before a given substring, according to the rules of the XPath substring-before() function- Specified by:
substringBefore
in interfaceSubstringMatcher
- Parameters:
s1
- the containing strings2
- the contained string- Returns:
- the part of s1 that precedes the first occurrence of s2
-
getCollationKey
public AtomicMatchKey getCollationKey(UnicodeString s)
Get a collation key for a String. The essential property of collation keys is that if (and only if) two strings are equal under the collation, then comparing the collation keys using the equals() method must return true.- Specified by:
getCollationKey
in interfaceStringCollator
- Overrides:
getCollationKey
in classSimpleCollation
- Parameters:
s
- the string whose collation key is required- Returns:
- the collation key
-
main
public static void main(java.lang.String[] args) throws java.lang.Exception
Test program to output the sequence of collation element iterators for a given input string- Parameters:
args
- command line arguments (collationURI, test-string)- Throws:
java.lang.Exception
- if any error occurs
