PartitionId (Google Cloud Spanner Parent 6.47.0 API)

java.lang.Object
- com.google.cloud.spanner.connection.PartitionId

All Implemented Interfaces:

Serializable
```
public class PartitionId
extends Object
implements Serializable
```
Contains a reference to a BatchTransactionId and a Partition. The combination of these two are needed to execute a partition of a partitioned query on a Connection. A PartitionId can safely be given to a different connection and/or host to be executed there.

- Method Detail
  - decodeFromString
```
public static PartitionId decodeFromString(String id)
```
    Deserializes a string representation of a PartitionId. The string must have been created with the encodeToString(BatchTransactionId, Partition) method.
  - encodeToString
```
public static String encodeToString(BatchTransactionId transactionId,
                                    Partition partition)
```
    Returns:
    
    A string-encoded version of this PartitionId. This encoded version can be sent to any other Connection to be executed there, including connections on different hosts than the current host.
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - getTransactionId
```
public BatchTransactionId getTransactionId()
```
  - getPartition
```
public Partition getPartition()
```
