  - insignificantNumericStringHandling
```
public static String insignificantNumericStringHandling(char[] source)
```
    Remove all insignificant spaces in a numeric string. For instance, the following numeric string : " 123 456 789 " will be transformed to : "123456789"
    
    Parameters:
    
    source - The numeric String
    
    Returns:
    
    The modified numeric String
  - insignificantTelephoneNumberStringHandling
```
public static String insignificantTelephoneNumberStringHandling(char[] source)
```
    Remove all insignificant spaces in a TelephoneNumber string, Hyphen and spaces. For instance, the following telephone number : "+ (33) 1-123--456 789" will be transformed to : "+(33)1123456789"
    
    Parameters:
    
    source - The telephoneNumber String
    
    Returns:
    
    The modified telephoneNumber String
  - insignificantSpacesStringValue
```
public static String insignificantSpacesStringValue(char[] origin)
```
    Remove all insignificant spaces in a string. Any resulting String will start with a space, ands with a space and every spaces found in the middle of the String will be aggregated into two consecutive spaces :
    
    empty string --> <space><space>
    
    A --> <space>A<space>
    
    <space>A --> <space>A<space>
    
    <space><space>A --> <space>A<space>

    Returns:
    
    The modified String
  - insignificantSpacesStringInitial
```
public static String insignificantSpacesStringInitial(char[] origin)
```
    Remove all insignificant spaces in a Initial assertion. A String will always start with one space, every space in the middle will be doubled and if there are spaces at the end, they will be replaced by one space :
    
    A --> <space>A
    
    <space>A --> <space>A
    
    <space><space>A --> <space>A
    
    A<space> --> <space>A<space>

    This method use a finite state machine to parse the text.
    Parameters:
    
    origin - The String to modify
    
    Returns:
    
    The modified String
  - insignificantSpacesStringAny
```
public static String insignificantSpacesStringAny(char[] origin)
```
    Remove all insignificant spaces in a Any assertion. A String starting with spaces will start with exactly one space, every space in the middle will be doubled and if there are spaces at the end, they will be replaced by one space :
    
    A --> A
    
    <space>A --> <space>A
    
    <space><space>A --> <space>A
    
    A<space> --> A<space>
    
    A<space><space> --> A<space>
    
    A<space>B --> A<space><space>B
    
    This method use a finite state machine to parse the text.
    Parameters:
    
    origin - The String to modify
    
    Returns:
    
    The modified String
  - insignificantSpacesStringFinal
```
public static String insignificantSpacesStringFinal(char[] origin)
```
    Remove all insignificant spaces in a string. This method use a finite state machine to parse the text.
    
    Parameters:
    
    origin - The String to modify
    
    Returns:
    
    The modified StringBuilder
