Method Detail

compare

public int compare(Object a, Object b)
Compare two string objects.

Returns: <0 if a0 if a>b

Throws: ClassCastException if the objects are of the wrong type for this Comparer

compareCS

public int compareCS(CharSequence a, CharSequence b)
Compare two CharSequence objects. This is hand-coded to avoid converting the objects into Strings.

Returns: <0 if a0 if a>b

Throws: ClassCastException if the objects are of the wrong type for this Comparer

contains

public boolean contains(String s1, 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

endsWith

public boolean endsWith(String s1, 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

getInstance

public static CodepointCollator getInstance()

startsWith

public boolean startsWith(String s1, 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

substringAfter

public 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

Parameters: s1 the containing string s2 the contained string

Returns: the part of s1 that follows the first occurrence of s2

substringBefore

public 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

Parameters: s1 the containing string s2 the contained string

Returns: the part of s1 that precedes the first occurrence of s2
