TokenType (Wrangler API 4.2.3 API)

java.lang.Object
- java.lang.Enum<TokenType>
- - io.cdap.wrangler.api.parser.TokenType

All Implemented Interfaces:

Serializable, Comparable<TokenType>
```
@PublicEvolving
public enum TokenType
extends Enum<TokenType>
implements Serializable
```
The TokenType class provides the enumerated types for different types of tokens that are supported by the grammar. Each of the enumerated types specified in this class also has associated object representing it. e.g. DIRECTIVE_NAME is represented by the object DirectiveName.

Bool, BoolList, ColumnName, ColumnNameList, DirectiveName, Numeric, NumericList, Properties, Ranges, Expression, Text, TextList

- Enum Constant Detail
  - DIRECTIVE_NAME
```
public static final TokenType DIRECTIVE_NAME
```
    Represents the enumerated type for the object DirectiveName type. This type is associated with the token that is recognized as a directive name within the recipe.
  - COLUMN_NAME
```
public static final TokenType COLUMN_NAME
```
    Represents the enumerated type for the object of ColumnName type. This type is associated with token that represents the column as defined by the grammar as :.
  - TEXT
```
public static final TokenType TEXT
```
    Represents the enumerated type for the object of Text type. This type is associated with the token that is either enclosed within a single quote(') or a double quote (") as string.
  - NUMERIC
```
public static final TokenType NUMERIC
```
    Represents the enumerated type for the object of Numeric type. This type is associated with the token that is either a integer or real number.
  - BOOLEAN
```
public static final TokenType BOOLEAN
```
    Represents the enumerated type for the object of Bool type. This type is associated with the token that either represents string 'true' or 'false'.
  - COLUMN_NAME_LIST
```
public static final TokenType COLUMN_NAME_LIST
```
    Represents the enumerated type for the object of type BoolList type. This type is associated with the rule that is a collection of Boolean values separated by comman(,). E.g. ColumnName[,ColumnName]*
  - TEXT_LIST
```
public static final TokenType TEXT_LIST
```
    Represents the enumerated type for the object of type TextList type. This type is associated with the comma separated text represented were each text is enclosed within a single quote (') or double quote (") and each text is separated by comma (,). E.g. Text[,Text]*
  - NUMERIC_LIST
```
public static final TokenType NUMERIC_LIST
```
    Represents the enumerated type for the object of type NumericList type. This type is associated with the collection of Numeric values separated by comma(,). E.g. Numeric[,Numeric]*
  - BOOLEAN_LIST
```
public static final TokenType BOOLEAN_LIST
```
    Represents the enumerated type for the object of type BoolList type. This type is associated with the collection of Bool values separated by comma(,). E.g. Boolean[,Boolean]*
  - EXPRESSION
```
public static final TokenType EXPRESSION
```
    Represents the enumerated type for the object of type Expression type. This type is associated with code block that either represents a condition or an expression. E.g. exp:{ }
  - PROPERTIES
```
public static final TokenType PROPERTIES
```
    Represents the enumerated type for the object of type Properties type. This type is associated with a collection of key and value pairs all separated by a comma(,). E.g. prop:{ =[,=]*}
  - RANGES
```
public static final TokenType RANGES
```
    Represents the enumerated type for the object of type Ranges types. This type is associated with a collection of range represented in the form shown below :=value[,:=value]*
  - IDENTIFIER
```
public static final TokenType IDENTIFIER
```
    Represents the enumerated type for the object of type String with restrictions on characters that can be present in a string.
- Method Detail
  - values
```
public static TokenType[] 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 (TokenType c : TokenType.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static TokenType 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
