alignLeftAndPad

public static java.lang.String alignLeftAndPad(java.lang.String text,
                                               int size)

Puts the text to the left and pads with spaces until the size is reached.

alignRightAndPad

public static java.lang.String alignRightAndPad(java.lang.String text,
                                                int size)

Puts the text to the right and pads it with spaces until the size is reached.

humanReadableByteCount

public static java.lang.String humanReadableByteCount(long bytes,
                                                      boolean useSi)

Formats byte size to human readable bytecount. https://stackoverflow.com/questions/3758606/how-to-convert-byte-size-into-human-readable-format-in-java/3758880#3758880

toPrettyString

public static java.lang.String toPrettyString(java.lang.Object value)

Converts object into pretty string. All arrays are iterated.

fromCamelCase

public static java.lang.String fromCamelCase(java.lang.String input,
                                             char separator)

Changes CamelCase string to lower case words separated by provided separator character. The following translations are applied:

• Every upper case letter in the CamelCase name is translated into two characters, a separator and the lower case equivalent of the target character, with three exceptions.
  1. For contiguous sequences of upper case letters, characters after the first character are replaced only by their lower case equivalent, and are not preceded by a separator (theFOO to the_foo).
  2. An upper case character in the first position of the CamelCase name is not preceded by a separator character, and is translated only to its lower case equivalent. (Foo to foo and not _foo)
  3. An upper case character in the CamelCase name that is already preceded by a separator character is translated only to its lower case equivalent, and is not preceded by an additional separator. (user_Name to user_name and not user__name.
• If the CamelCase name starts with a separator, then that separator is not included in the translated name, unless the CamelCase name is just one character in length, i.e., it is the separator character. This applies only to the first character of the CamelCase name.

toCamelCase

public static java.lang.String toCamelCase(java.lang.String input,
                                           boolean firstCharUppercase,
                                           char separator)

Converts separated string value to CamelCase.

formatParagraph

public static java.lang.String formatParagraph(java.lang.String src,
                                               int len,
                                               boolean breakOnWhitespace)

Formats provided string as paragraph.

convertTabsToSpaces

public static java.lang.String convertTabsToSpaces(java.lang.String line,
                                                   int tabWidth)

Converts all tabs on a line to spaces according to the provided tab width. This is not a simple tab to spaces replacement, since the resulting indentation remains the same.

escapeJava

public static java.lang.String escapeJava(java.lang.String string)

Escapes a string using java rules.

unescapeJava

public static java.lang.String unescapeJava(java.lang.String str)

Unescapes a string using java rules.
