RegexpFlag (core 5.6.16 API)

java.lang.Object
- java.lang.Enum<RegexpFlag>
- - org.elasticsearch.index.query.RegexpFlag

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<RegexpFlag>
```
public enum RegexpFlag
extends java.lang.Enum<RegexpFlag>
```
Regular expression syntax flags. Each flag represents optional syntax support in the regular expression:
- INTERSECTION - Support for intersection notation: <expression> & <expression>
- COMPLEMENT - Support for complement notation: <expression> & <expression>
- EMPTY - Support for the empty language symbol: #
- ANYSTRING - Support for the any string symbol: @
- INTERVAL - Support for numerical interval notation: <n-m>
- NONE - Disable support for all syntax options
- ALL - Enables support for all syntax options

public static final RegexpFlag COMPLEMENT
```
    Enables complement expression of the form: ~<expression>
  - EMPTY
```
public static final RegexpFlag EMPTY
```
    Enables empty language expression: #
  - ANYSTRING
```
public static final RegexpFlag ANYSTRING
```
    Enables any string expression: @
  - INTERVAL
```
public static final RegexpFlag INTERVAL
```
    Enables numerical interval expression: <n-m>

public static final RegexpFlag NONE
```
    Disables all available option flags
  - ALL
```
public static final RegexpFlag ALL
```
    Enables all available option flags
- Method Detail
  - values
```
public static RegexpFlag[] 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 (RegexpFlag c : RegexpFlag.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static RegexpFlag valueOf(java.lang.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:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - value
```
public int value()
```
  - resolveValue
```
public static int resolveValue(java.lang.String flags)
```
    Resolves the combined OR'ed value for the given list of regular expression flags. The given flags must follow the following syntax:
    flag_name(|flag_name)*
    Where flag_name is one of the following:
    - INTERSECTION
    - COMPLEMENT
    - EMPTY
    - ANYSTRING
    - INTERVAL
    - NONE
    - ALL
    Example: INTERSECTION|COMPLEMENT|EMPTY
    Parameters:
    
    flags - A string representing a list of regular expression flags
    
    Returns:
    
    The combined OR'ed value for all the flags
