Class Binary.BinaryStream

java.lang.Object
org.rapidcontext.core.data.Binary.BinaryStream
All Implemented Interfaces:
Binary
Enclosing interface:
Binary
public static class Binary.BinaryStream extends Object implements Binary
A binary data object, encapsulating an input stream. This wrapper breaks the Binary contract slightly, since new streams cannot be opened.
Version:
1.0

    • BinaryStream

      public BinaryStream(InputStream is, int size)
      Creates a new binary stream wrapper.

      sha256 in interface Binary
      Returns:
      the hexadecimal string with the SHA-256 hash, or null if not available

    • openStream

      public InputStream openStream() throws IOException
