Method Detail

mapReplace

public static java.lang.String mapReplace(java.lang.String source,
                                          java.util.Map<java.lang.String,java.lang.String> map,
                                          java.lang.String keyPrefix,
                                          java.lang.String keySuffix)

Returns a modified version of the given source string. In this modified version, any occurrence of any of the keys within the given map is replaced by the associated value.

If a value in the provided key/value map is null, then the associated key will be replaced by a blank string within the modified version of the source string.

If a keyPrefix or keySuffix is specified, then they will be appended to the key prior to the replace operation.

Parameters:

source - the source string

map - the key/value map

keyPrefix - appended to the beginning of the key before the replace operation. Example: key='node-name', prefix='%' => replacing occurrences of '%node-name'

keySuffix - appended to the ending of the key before the replace operation. Example: key='node-name', prefix='%' => replacing occurrences of 'node-name%'

Returns:

the modified version of the source string

mapReplace

public static java.lang.String mapReplace(java.lang.String source,
                                          java.util.Map<java.lang.String,java.lang.String> map)

Convenience method calling mapReplace(String, Map, String, String) without prefix and suffix

spacelessCaseInsensitiveCompare

public static boolean spacelessCaseInsensitiveCompare(java.lang.String str1,
                                                      java.lang.String str2)

Compares the two given strings while ignoring case and white spaces. If both strings are null, then the comparison result is TRUE. If one string is null and the other one isn't, then the comparison result is FALSE.

wordCount

public static int wordCount(java.lang.String string,
                            java.lang.String delimiter)

Counts the words in the given string using the given word delimiter

Returns:

word count or 0 if the string is null

wordCount

public static int wordCount(java.lang.String string)

Counts the words in the given string assuming the words are split by a space character

Returns:

word count or 0 if the string is null

extractWord

public static java.lang.String extractWord(java.lang.String string,
                                           int wordNumber)

Attempts to find the N'th word in the given string. N is given by the wordNumber argument

Returns:

the N'th word or null in case the given string is null or doesn't have at least N words
