All Implemented Interfaces:

com.amplitude.android.sessionreplay.storage.GenericStorage
```
public class PersistentStorage
 implements GenericStorage
                    
```
PersistentStorage is a file-based storage implementation
There are a few main components to the storage:
- Properties - currentSequenceId, etc
- Data - blob of data, this will be store in file storage

Method Summary

Modifier and Type	Method	Description
`final String`	`get(String key)`

 final String get(String key)
```
  - get
```
 String get(String key, String defaultValue)
```
    Get stored value for key
  - set
```
 Unit set(String key, String value)

  - serializeData
```
 String serializeData(Object data)
```
    By default we serialize data to a string using toString().
    This should be overridden by subclasses to provide custom serialization.
  - deserializeData
```
 Object deserializeData(String data)
```
    By default we return the data as a string. (unchanged)
    This should be overridden by subclasses to provide custom serialization.
  - generateNextDataBlockUri
```
 String generateNextDataBlockUri()
```
    By default we generate a new data block URI using the current time.
    This should be overridden by subclasses to provide custom file naming.
  - writeData
```
 Unit writeData(Object data)
```
    Store generic data with optional callback and identifier
    
    Parameters:
    
    data - : Data to be stored
  - writeDataList
```
 Unit writeDataList(List<Object> data)
```
    Write all data at once for performance reasons.
  - readDataBlock
```
 String readDataBlock(String uri)
```
    Read stored data content for given URI, return null if not found
  - readDataBlockItems
```
 List<String> readDataBlockItems(String uri)
```
    Read stored data content for given URI split into individual items based on delimiter Return null if not found
