ValueType (Protempa Framework 3.0-Alpha-13 API)

java.lang.Object
- java.lang.Enum<ValueType>
- - org.protempa.proposition.value.ValueType

All Implemented Interfaces:

Serializable, Comparable<ValueType>
```
public enum ValueType
extends Enum<ValueType>
```
Represents types of values of propositions and properties, and provides a method for parsing them from strings.

```
public static ValueType[] 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 (ValueType c : ValueType.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ValueType 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
  - isInstance
```
public abstract boolean isInstance(Value value)
```
    Returns whether a value is an instance of this value type.
    
    Parameters:
    
    value - a Value.
    
    Returns:
    
    true or false.
  - parse
```
public abstract Value parse(String val)
```
    Creates a Value instance by parsing the given string.
    
    Parameters:
    
    val - a String. May be null.
    
    Returns:
    
    a Value, or null if the supplied string is null or has an invalid format.
