Maping S3ObjectInputStream into input stream

Question

I am working with AWS Java api.

Retrieving file returns S3Object that contains S3ObjectInputStream which i read data from.

However, i would like to map S3ObjectInputStream into normal InputStream , is something like that possible?

I would love to create API that hides this implementation.

I know if i have small file i can just store bytes in array and create InputStream from that, but big files will be needed too.

Thanks for help!

For S3 Java 1, refer to this example:

https://github.com/awsdocs/aws-doc-sdk-examples/blob/master/java/example_code/s3/src/main/java/GetObject.java

If you are using V2, see this client method. You can get a byte[] and then use that to meet your requirements:
