Asto stands for Abstract Storage, an abstraction over physical data storage system. The main entity of the library is an interface com.artipie.asto.Storage, a contract which requires to implement the following functionalities:

• put/get operations
• transaction support
• list files in a directory
• check if a file/directory exists

Supported abstractions:

• File system
• S3

This is the dependency you need:

<dependency>
  <groupId>com.artipie</groupId>
  <artifactId>asto</artifactId>
  <version>[...]</version>
</dependency>

Read the Javadoc for more technical details.

Create a hello.txt file with "Hello World!" content on file-system-based storage in blocking way:

final BlockingStorage storage = new BlockingStorage(
    new FileStorage(
        Files.createTempDirectory("temp-blocking")
    )
).save(new Key.From("hello.txt"), "Hello World!".getBytes());

The same with RxJava2 way:

new RxStorageWrapper(
    new FileStorage(
        Files.createTempDirectory("temp-rx")
    )
).save(
    new Key.From("hello.txt"),
    ByteBuffer.wrap("Hello World!".getBytes())
);
