- Enum Constant Detail
  - BLOCK
```
public static final IndexType BLOCK
```
    Block records by key fields.
  - FULL
```
public static final IndexType FULL
```
    Compare all records to all records using cartesian product of the sources.
  - HASHJOIN
```
public static final IndexType HASHJOIN
```
    Hash join inputs when linking.
  - INEQUALITYJOIN
```
public static final IndexType INEQUALITYJOIN

- Method Detail
  - values
```
public static IndexType[] 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 (IndexType c : IndexType.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static IndexType 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
