StatementEnum (Blazegraph Database Platform 2.1.5 API)

java.lang.Object
- java.lang.Enum<StatementEnum>
- - com.bigdata.rdf.model.StatementEnum

All Implemented Interfaces:

Serializable, Comparable<StatementEnum>
```
public enum StatementEnum
extends Enum<StatementEnum>
```
The basic statement types are: axioms, explicit, inferred.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`Axiom` Something that is directly entailed by the appropriate model theory.
`Explicit` A statement that was inserted into the database explicitly by the application.
`History` An explicit statement that was deleted but is being maintained in the statement indices for history.
`Inferred` A statement that was inferred from the explicit statements by the appropriate model theory.

Field Summary

Fields
Modifier and Type	Field and Description
`static int`	`MASK_OVERRIDE` A bit mask used to isolate the bit that indicates that the existing statement type should be overridden thereby allowing the downgrade of a statement from explicit to inferred.
`static int`	`MASK_USER_FLAG` A user bit mask used by applications to flag statements.

Method Summary

Methods
Modifier and Type	Method and Description
`byte`	`code()`
`static StatementEnum`	`decode(byte b)` Decode a byte into a `StatementEnum`.
`static StatementEnum`	`deserialize(byte[] val)`
`static boolean`	`isOverride(byte b)` Return `true` iff the override bit is set.
`static boolean`	`isUserFlag(byte b)` Return `true` iff the user bit is set.
`static StatementEnum`	`max(StatementEnum a, StatementEnum b)` Max returns the value that is first in the total order Explicit Axiom Inferred Deleted
`byte[]`	`serialize()`
`static StatementEnum`	`valueOf(String name)` Returns the enum constant of this type with the specified name.
`static StatementEnum[]`	`values()` Returns an array containing the constants of this enum type, in the order they are declared.

- Enum Constant Detail
  - Explicit
```
public static final StatementEnum Explicit
```
    A statement that was inserted into the database explicitly by the application.
  - Axiom
```
public static final StatementEnum Axiom
```
    Something that is directly entailed by the appropriate model theory.
  - Inferred
```
public static final StatementEnum Inferred
```
    A statement that was inferred from the explicit statements by the appropriate model theory.
  - History
```
public static final StatementEnum History
```
    An explicit statement that was deleted but is being maintained in the statement indices for history.
- Field Detail
  - MASK_OVERRIDE
```
public static final int MASK_OVERRIDE
```
    A bit mask used to isolate the bit that indicates that the existing statement type should be overridden thereby allowing the downgrade of a statement from explicit to inferred.

    Constant Field Values
  - MASK_USER_FLAG
```
public static final int MASK_USER_FLAG
```
    A user bit mask used by applications to flag statements.

```
public static StatementEnum[] 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 (StatementEnum c : StatementEnum.values())
    System.out.println(c);
```
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static StatementEnum 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
  - code
```
public byte code()
```
  - max
```
public static StatementEnum max(StatementEnum a,
                StatementEnum b)
```
    Max returns the value that is first in the total order
    - Explicit
    - Axiom
    - Inferred
    - Deleted
    Parameters:
    a -
    b -
    
    Returns:
  - decode
```
public static StatementEnum decode(byte b)
```
    Decode a byte into a StatementEnum.
    Note: The override bit is masked off during this operation.
    
    Parameters:
    b - The byte.
    
    Returns:
    The StatementEnum value.
  - deserialize
```
public static StatementEnum deserialize(byte[] val)
```
  - serialize
```
public byte[] serialize()
```
  - isUserFlag
```
public static boolean isUserFlag(byte b)
```
    Return true iff the user bit is set.
    
    Parameters:
    b - The byte.
  - isOverride
```
public static boolean isOverride(byte b)
```
    Return true iff the override bit is set.
    
    Parameters:
    b - The byte.
