## Enum CorsFilter.CORSRequestType

- java.lang.Object
- - java.lang.Enum<CorsFilter.CORSRequestType>
  - - org.apache.catalina.filters.CorsFilter.CORSRequestType

- All Implemented Interfaces:
    `Serializable`, `Comparable<CorsFilter.CORSRequestType>`
  Enclosing class:
    CorsFilter

      protected static enum CorsFilter.CORSRequestType
      extends Enum<CorsFilter.CORSRequestType>

  Enumerates varies types of CORS requests. Also, provides utility methods to determine the request type.

- - ### Enum Constant Summary

    Enum Constants
    Enum Constant | Description
    --- | ---
    `ACTUAL` | An HTTP request that needs to be pre-flighted.
    `INVALID_CORS` | An invalid CORS request, i.e. it qualifies to be a CORS request, but fails to be a valid one.
    `NOT_CORS` | Not a CORS request, but a normal request.
    `PRE_FLIGHT` | A pre-flight CORS request, to get meta information, before a non-simple HTTP request is sent.
    `SIMPLE` | A simple HTTP request, i.e. it shouldn't be pre-flighted.

      An HTTP request that needs to be pre-flighted.

    - #### PRE_FLIGHT

          public static final CorsFilter.CORSRequestType PRE_FLIGHT

      A pre-flight CORS request, to get meta information, before a non-simple HTTP request is sent.

  - ### Method Detail

    - #### values

          public static CorsFilter.CORSRequestType[] 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 (CorsFilter.CORSRequestType c : CorsFilter.CORSRequestType.values())
              System.out.println(c);

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

    - #### valueOf

          public static CorsFilter.CORSRequestType 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
