All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`int`	`getValue()`

- Method Detail
  - values
```
public static Operator[] 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 (Operator c : Operator.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Operator valueOf(java.lang.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:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - writeTo
```
public void writeTo(java.io.DataOutput output)
             throws java.io.IOException
```
    Write the serialized version of this Operator to the specified output.
    
    Parameters:
    
    output - the output to write to
    
    Throws:
    
    java.io.IOException - if an I/O problem occurs while writing to the specified output
  - getValue
```
public int getValue()
```
  - readFrom
```
public static Operator readFrom(java.io.DataInput input)
                         throws java.io.IOException
```
    Deserializes a Operator instance from the specified input.
    
    Parameters:
    
    input - the input to read from
    
    Returns:
    
    the Operator instance deserialized
    
    Throws:
    
    java.io.IOException - if a problem occurs while deserializing the Type instance.
  - isSatisfiedBy
```
public boolean isSatisfiedBy(AbstractType<?> type,
                             java.nio.ByteBuffer leftOperand,
                             java.nio.ByteBuffer rightOperand)
```
    Whether 2 values satisfy this operator (given the type they should be compared with).
    
    Throws:
    
    java.lang.AssertionError - for CONTAINS and CONTAINS_KEY as this doesn't support those operators yet
  - serializedSize
```
public int serializedSize()
```
  - isSlice
```
public boolean isSlice()
```
    Checks if this operator is a slice operator.
    
    Returns:
    
    true if this operator is a slice operator, false otherwise.
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Enum<Operator>
