KeyValue (TIBCO Streaming Product Javadoc 10.6.1 API)

All Known Implementing Classes:

HashableTuple
```
public interface KeyValue
```
KeyValue represents a specific value of the primary key, as taken from the Tuple in a specific Table, including if the Table has a complex key involving multiple fields. KeyValues can be compared using .equals and can be used as the key in HashMaps, such that if you get a new record, a KeyValue extracted from it will match to a KeyValue from an existing record.

- Method Detail
  - equals
```
boolean equals(Object other)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
int hashCode()
```
    Returns a int hashcode for this KeyValue. hashcodes may collide for complex keys in large result sets.
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    32 bit hashcode for this KeyValue
  - getValueAsUniqueString
```
String getValueAsUniqueString()
```
    Returns an opaque unique String that can be used to identify this tuple. What this String looks like may change from release to release so should not be persisted.
    
    Returns:
    
    - Unique String that identifies this KeyValue
