org.xenei.classpathutils.Case

All Implemented Interfaces:

Serializable

public final class Case
extends Object
implements Serializable

Enumeration of class name case sensitivity.

This class captures difference case sensitivity, providing an enumeration to control how filename comparisons should be performed. It also provides methods that use the enumeration to perform comparisons.

Wherever possible, you should use the check methods in this class to compare filenames.

The constant for case sensitive regardless of operating system.

INSENSITIVE

public static final Case INSENSITIVE

The constant for case insensitive regardless of operating system.

Method Detail

forName

public static Case forName(String name)

Factory method to create a Case from a name.

Parameters:

name - the name to find

Returns:

the Case object

Throws:

IllegalArgumentException - if the name is invalid

getName

public String getName()

Gets the name of the constant.

Returns:

the name of the constant

isCaseSensitive

public boolean isCaseSensitive()

Does the object represent case sensitive comparison.

Returns:

true if case sensitive

checkCompareTo

public int checkCompareTo(String str1,
                          String str2)

Compares two strings using the case-sensitivity rule.

This method mimics String.compareTo(java.lang.String) but takes case-sensitivity into account.

Parameters:

str1 - the first string to compare, not null

str2 - the second string to compare, not null

Returns:

true if equal using the case rules

Throws:

NullPointerException - if either string is null

checkEquals

public boolean checkEquals(String str1,
                           String str2)

Compares two strings using the case-sensitivity rule.

This method mimics String.equals(java.lang.Object) but takes case-sensitivity into account.

Parameters:

str1 - the first string to compare, not null

str2 - the second string to compare, not null

Returns:

true if equal using the case rules

Throws:

NullPointerException - if either string is null

checkStartsWith

public boolean checkStartsWith(String str,
                               String start)

Checks if one string starts with another using the case-sensitivity rule.

This method mimics String.startsWith(String) but takes case-sensitivity into account.

Parameters:

str - the string to check, not null

start - the start to compare against, not null

Returns:

true if equal using the case rules

Throws:

NullPointerException - if either string is null

checkEndsWith

public boolean checkEndsWith(String str,
                             String end)

Checks if one string ends with another using the case-sensitivity rule.

This method mimics String.endsWith(java.lang.String) but takes case-sensitivity into account.

Parameters:

str - the string to check, not null

end - the end to compare against, not null

Returns:

true if equal using the case rules

Throws:

NullPointerException - if either string is null

checkIndexOf

public int checkIndexOf(String str,
                        int strStartIndex,
                        String search)

Checks if one string contains another starting at a specific index using the case-sensitivity rule.

This method mimics parts of String.indexOf(String, int) but takes case-sensitivity into account.

Parameters:

str - the string to check, not null

strStartIndex - the index to start at in str

search - the start to search for, not null

Returns:

the first index of the search String, -1 if no match or null string input

Throws:

NullPointerException - if either string is null

Since:

2.0

checkRegionMatches

public boolean checkRegionMatches(String str,
                                  int strStartIndex,
                                  String search)

Checks if one string contains another at a specific index using the case-sensitivity rule.

This method mimics parts of String.regionMatches(boolean, int, String, int, int) but takes case-sensitivity into account.

Parameters:

str - the string to check, not null

strStartIndex - the index to start at in str

search - the start to search for, not null

Returns:

true if equal using the case rules

Throws:

NullPointerException - if either string is null

toString

public String toString()

Gets a string describing the sensitivity.

Overrides:

toString in class Object

Returns:

a string describing the sensitivity
