Interface SubstringMatcher

All Superinterfaces:

java.util.Comparator

All Known Implementing Classes:

CodepointCollator, RuleBasedSubstringMatcher

public interface SubstringMatcher

extends java.util.Comparator

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.

Method Summary

boolean	contains(java.lang.String s1, java.lang.String s2) Test whether one string contains another, according to the rules of the XPath contains() function
boolean	endsWith(java.lang.String s1, java.lang.String s2) Test whether one string ends with another, according to the rules of the XPath ends-with() function
boolean	startsWith(java.lang.String s1, java.lang.String s2) Test whether one string starts with another, according to the rules of the XPath starts-with() function
java.lang.String	substringAfter(java.lang.String s1, java.lang.String s2) Return the part of a string after a given substring, according to the rules of the XPath substring-after() function
java.lang.String	substringBefore(java.lang.String s1, java.lang.String s2) Return the part of a string before a given substring, according to the rules of the XPath substring-before() function

Method Detail

contains

public boolean contains(java.lang.String s1,
                        java.lang.String s2)

Test whether one string contains another, according to the rules of the XPath contains() function

Parameters:

s1 - the containing string

s2 - the contained string

Returns:

true iff s1 contains s2

startsWith

public boolean startsWith(java.lang.String s1,
                          java.lang.String s2)

Test whether one string starts with another, according to the rules of the XPath starts-with() function

Parameters:

s1 - the containing string

s2 - the contained string

Returns:

true iff s1 starts with s2

endsWith

public boolean endsWith(java.lang.String s1,
                        java.lang.String s2)

Test whether one string ends with another, according to the rules of the XPath ends-with() function

Parameters:

s1 - the containing string

s2 - the contained string

Returns:

true iff s1 ends with s2

substringBefore

public java.lang.String substringBefore(java.lang.String s1,
                                        java.lang.String s2)

Return the part of a string before a given substring, according to the rules of the XPath substring-before() function

Parameters:

s1 - the containing string

s2 - the contained string

Returns:

the part of s1 that precedes the first occurrence of s2

substringAfter

public java.lang.String substringAfter(java.lang.String s1,
                                       java.lang.String s2)

Return the part of a string after a given substring, according to the rules of the XPath substring-after() function

Parameters:

s1 - the containing string

s2 - the contained string

Returns:

the part of s1 that follows the first occurrence of s2
