## Enum NodeNameMatchers

- java.lang.Object
- - java.lang.Enum<NodeNameMatchers>
  - - org.apache.commons.configuration2.tree.NodeNameMatchers

- All Implemented Interfaces:
    Serializable, Comparable<NodeNameMatchers>, NodeMatcher<String>

      public enum NodeNameMatchers
      extends Enum<NodeNameMatchers>
      implements NodeMatcher<String>

  An enumeration class with several pre-defined `NodeMatcher` implementations based on node names.

  Filtering nodes by their name is a typical use case. Therefore, some default implementations for typical filter algorithms are already provided. They are available as constants of this class. Because the algorithms are state-less these instances can be shared and accessed concurrently.

  Since:
    2.0

    Enum Constants
    Enum Constant and Description
    `EQUALS` A matcher for exact node name matches.
    `EQUALS_IGNORE_CASE` A matcher for matches on node names which ignores case.

    All Methods Static Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `static NodeNameMatchers` | `valueOf(String name)` Returns the enum constant of this type with the specified name.
    `static NodeNameMatchers[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

- - ### Enum Constant Detail

    - #### EQUALS

          public static final NodeNameMatchers EQUALS

      A matcher for exact node name matches. This matcher returns true if and only if the name of the passed in node equals exactly the given criterion string.

    - #### EQUALS_IGNORE_CASE

          public static final NodeNameMatchers EQUALS_IGNORE_CASE

      A matcher for matches on node names which ignores case. For this matcher the names `node`, `NODE`, or `NodE` are all the same.

  - ### Method Detail

    - #### values

          public static NodeNameMatchers[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (NodeNameMatchers c : NodeNameMatchers.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static NodeNameMatchers valueOf(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null
