- java.lang.Enum<EvaluationMode>
- - net.sf.saxon.expr.EvaluationMode

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<EvaluationMode>
```
public enum EvaluationMode
extends java.lang.Enum<EvaluationMode>
```
An evaluation mode represents a way in which expressions can be evaluated

- Method Detail
  - values
```
public static EvaluationMode[] 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 (EvaluationMode c : EvaluationMode.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static EvaluationMode 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
  - getCode
```
public int getCode()
```
    Get the integer code associated with an evaluation mode. These codes should be considered stable, as they are recorded in SEF files
    
    Returns:
    
    an integer code
  - getEvaluator
```
public Evaluator getEvaluator()
```
    Get the evaluator corresponding to a particular evaluation mode
    
    Returns:
    
    the corresponding evaluator
  - forCode
```
public static EvaluationMode forCode(int code)
```
    Get the evaluation mode with a particular integer code. This is used when reloading a stylesheet from a SEF file
    
    Parameters:
    
    code - the integer code
    
    Returns:
    
    the corresponding evaluation mode
