Content Engine Java API: MergeMode

java.lang.Object
- com.filenet.api.constants.MergeMode

All Implemented Interfaces:

java.io.Serializable
```
public class MergeMode
extends java.lang.Object
implements java.io.Serializable
```
Determines how the search results are merged for searches across multiple repositories. The merge mode can be either:
- The intersection of all classes found (INTERSECTION). The search results will contain the classes occurring in every repository searched.
- The union of all classes found (UNION). The search results will contain the classes occurring in any repository searched.
When the merge mode is UNION and a class or property is not found in any repository, the following occurs:
- For classes, an inner join returns no rows, and an outer join returns nulls. Join types are specified in the JoinOperator class
- For properties, the property value is null in a selection list or WHERE clause, and is omitted from an ORDER BY clause.

Method Summary

Methods
Modifier and Type	Method and Description
`static MergeMode`	`getInstanceFromInt(int value)` Gets the instance of this class using its associated integer value (the *_AS_INT fields).
`int`	`getValue()` Returns an integer value associated with a specific instance of this class.

- Field Detail
  - INTERSECTION_AS_INT
```
public static final int INTERSECTION_AS_INT
```
    An integer associated with the INTERSECTION instance of this class.
    Use the static instances of this class, rather than the associated integer values. The integer values risk binary incompatibility (but not source incompatibility) across product releases.
    
    See Also:
    Constant Field Values
  - INTERSECTION
```
public static final MergeMode INTERSECTION
```
    A constant representing a MergeMode instance of type INTERSECTION. This specifies that the search result is the intersection of the classes found across the repositories (the classes occurring in every repository searched).
    
    See Also:
    getValue(), getInstanceFromInt(int)
  - UNION_AS_INT
```
public static final int UNION_AS_INT
```
    An integer associated with the UNION instance of this class.
    Use the static instances of this class, rather than the associated integer values. The integer values risk binary incompatibility (but not source incompatibility) across product releases.
    
    See Also:
    Constant Field Values
  - UNION
```
public static final MergeMode UNION
```
    A constant representing a MergeMode instance of type UNION. This specifies that the search result is the union of the classes found across the repositories (the classes occurring in any repository searched).

    getValue(), getInstanceFromInt(int)
- Method Detail
  - getValue
```
public int getValue()
```
    Returns an integer value associated with a specific instance of this class.
    
    Returns:
    An integer representing a specific instance of this class.
  - getInstanceFromInt
```
public static MergeMode getInstanceFromInt(int value)
```
    Gets the instance of this class using its associated integer value (the *_AS_INT fields).
    
    Parameters:
    value - An integer representing a particular static instance of this class.
    
    Returns:
    The MergeMode instance referenced.
    
    Throws:
    
    EngineRuntimeException - Thrown when the parameter is null or invalid.
  - toString
```
public java.lang.String toString()
```
    Returns a String representation of this instance.
    
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
    A String representing the instance.
