Class AsciiSet

java.lang.Object

com.netflix.spectator.impl.AsciiSet

public final class AsciiSet
extends java.lang.Object

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.

Method Detail

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.

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.
