net.sf.saxon.expr.sort.RuleBasedSubstringMatcher
- All Implemented Interfaces:
StringCollator
,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().

- the collation to be used

Method Details
-
contains
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
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
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
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
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
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
Test program to output the sequence of collation element iterators for a given input string- Parameters:
args
- command line arguments (collationURI, test-string)- Throws:
Exception
- if any error occurs
