Class TextUtils

java.lang.Object

com.day.text.TextUtils

public class TextUtils
extends java.lang.Object

Simple text manipulation tasks - these aren't optimized, and are intended primarily to be used by test code. (eg. to compare returned values from functions with the values expected).

Method Detail

removeControlCharacters

public static java.lang.String removeControlCharacters(java.lang.String characters)

removeWhitespace

public static java.lang.String removeWhitespace(java.lang.String characters)

isTextSimilar

public static boolean isTextSimilar(java.lang.String docOne,
                                    java.lang.String docTwo)

Compare two strings, and determine whether they are approximately "similar" - by this we mean whether they have the same numbers of each character in (barring whitespace). We do this by sorting the strings as a character array and stripping whitespace.

This will generate false positives on some text - for example anagrams.

For example, the text "Watch the carthorse" and "Watch the orchestra" will both be converted to "aacceehhhorrstttw" and compared - so they will be identical.

This method is mostly useful as a simple way of comparing data which can be differently ordered but still functionally equivalent - for example DTDs.

noisyIsTextSimilar

public static boolean noisyIsTextSimilar(java.lang.String docOne,
                                         java.lang.String docTwo)

stripWhitespace

public java.lang.String stripWhitespace(java.lang.String s)

Remove all whitespace from a string - most useful for test purposes (where you compare two strings, but whitespace isn't syntactically significant)

sanitizeForCommunique

public static java.lang.String sanitizeForCommunique(java.lang.String s)

These are characters not allowed in a text string in a CQ any file - they require escaping.

replace

public static java.lang.String replace(java.lang.String allOfTheText,
                                       java.lang.String toFind,
                                       java.lang.String toReplace)

Search and replace

trimTrailingSlashes

public static java.lang.String trimTrailingSlashes(java.lang.String input)

trimLeadingSlashes

public static java.lang.String trimLeadingSlashes(java.lang.String input)

occursOnceOnly

public static boolean occursOnceOnly(java.lang.String big,
                                     java.lang.String small)

occursExactlyNTimes

public static boolean occursExactlyNTimes(java.lang.String big,
                                          java.lang.String small,
                                          int n)

countOccurences

public static int countOccurences(java.lang.String big,
                                  java.lang.String small)

trimLastSlashLevel

public static java.lang.String trimLastSlashLevel(java.lang.String input)

Removes last level from a "slashy string" representaion of a hierarchical path. For example, '/a/b/c' becomes '/a/b' with the exception that '/' and '' remain unchanged
