AsciiSet (Spectator)

java.lang.Object
- com.netflix.spectator.impl.AsciiSet

All Implemented Interfaces:

java.io.Serializable
```
public final class AsciiSet
extends java.lang.Object
implements java.io.Serializable
```
Utility class for quickly checking if a string contains only characters contained within the given set. The set is limited to basic ascii with ranges, if you need more advanced patterns then regular expressions are a better option though it will likely come with a steep performance penalty.
This class is an internal implementation detail only intended for use within spectator. It is subject to change without notice.

  - fromPattern
```
public static AsciiSet fromPattern(java.lang.String pattern)
```
    Create a set containing ascii characters using a simple pattern. The pattern is similar to a character set in regex. For example, ABC would contain the characters A, B, and C. Ranges are supported so all uppercase letters could be specified as A-Z. The dash, -, will be included as part of the set if it is at the start or end of the pattern.
    
    Parameters:
    
    pattern - String specification of the character set.
    
    Returns:
    
    Set containing the characters specified in pattern.
  - none
```
public static AsciiSet none()
```
    Returns a set that matches no characters.
  - all
```
public static AsciiSet all()
```
    Returns a set that matches all ascii characters.
  - control
```
public static AsciiSet control()
```
    Returns a set that matches ascii control characters.
  - contains
```
public boolean contains(char c)
```
    Returns true if the character contained within the set. This is a constant time operation.
  - containsAll
```
public boolean containsAll(java.lang.CharSequence str)
```
    Returns true if all characters in the string are contained within the set.
  - replaceNonMembers
```
public java.lang.String replaceNonMembers(java.lang.String input,
                                          char replacement)
```
    Replace all characters in the input string with the replacement character.
  - union
```
public AsciiSet union(AsciiSet set)
```
    Returns a new set that will match characters either in the this set or in the set that is provided.
  - intersection
```
public AsciiSet intersection(AsciiSet set)
```
    Returns a new set that will match characters iff they are included this set and in the set that is provided.
  - diff
```
public AsciiSet diff(AsciiSet set)
```
    Returns a new set that will match characters iff they are included this set and not in the set that is provided.
  - invert
```
public AsciiSet invert()
```
    Returns a new set that will match characters that are not included this set.
  - character
```
public java.util.Optional<java.lang.Character> character()
```
    If this set matches a single character, then return an optional with that character. Otherwise return an empty optional.
  - isEmpty
```
public boolean isEmpty()
```
    Returns true if this set is isEmpty.
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class java.lang.Object
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Overrides:
    
    equals in class java.lang.Object
