Method Detail

compareString

public int compareString(java.lang.String a,
                         java.lang.String b,
                         boolean ignoreCase)

Description copied from class: CompareMode

Compare two strings.

Overrides:

compareString in class CompareMode

Parameters:

a - the first string

b - the second string

ignoreCase - true if a case-insensitive comparison should be made

Returns:

-1 if the first string is 'smaller', 1 if the second string is smaller, and 0 if they are equal

equalsChars

public boolean equalsChars(java.lang.String a,
                           int ai,
                           java.lang.String b,
                           int bi,
                           boolean ignoreCase)

Description copied from class: CompareMode

Compare two characters in a string.

Overrides:

equalsChars in class CompareMode

Parameters:

a - the first string

ai - the character index in the first string

b - the second string

bi - the character index in the second string

ignoreCase - true if a case-insensitive comparison should be made

Returns:

true if the characters are equals
