EffectType (General SQL Parser Java Library Core 4.1.0.3 API)

Object
- Enum<EffectType>
- - gudusoft.gsqlparser.ir.common.EffectType

All Implemented Interfaces:

Serializable, Comparable<EffectType>
```
public enum EffectType
extends Enum<EffectType>
```
Data effect type for lineage edges and procedural data flow edges. Describes how a value is transformed from source to target.

```
    Function/expression transformation. Example: SELECT UPPER(a) FROM t
  - AGGREGATION
```
public static final EffectType AGGREGATION
```
    Aggregation causes granularity change. Example: SELECT SUM(a) FROM t

public static final EffectType AMBIGUOUS
```
    Dynamic SQL or ambiguous path. Example: EXECUTE IMMEDIATE
  - WINDOW_FUNCTION
```
public static final EffectType WINDOW_FUNCTION
```
    Window function transformation. Example: SELECT ROW_NUMBER() OVER(...)
  - TYPE_CAST
```
public static final EffectType TYPE_CAST
```
    Type cast. Example: CAST(a AS VARCHAR)
  - CONDITIONAL
```
public static final EffectType CONDITIONAL

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