  - values
```
public static LoadMetadataType[] 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 (LoadMetadataType c : LoadMetadataType.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static LoadMetadataType 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
  - getValue
```
public int getValue()
```
    Returns:
    
    the integer value of the LoadMetadataType
  - toThrift
```
public static LoadMetadataTType toThrift(LoadMetadataType loadMetadataType)
```
    Parameters:
    
    loadMetadataType - the LoadMetadataType
    
    Returns:
    
    the thrift representation of this enum
  - fromThrift
```
@Nullable
public static LoadMetadataType fromThrift(LoadMetadataTType loadMetadataTType)
```
    Parameters:
    
    loadMetadataTType - the thrift representation of loadMetadataType
    
    Returns:
    
    the LoadMetadataType
