Base64InputStream

AI-generated Key Takeaways

• Base64InputStream is a subclass of FilterInputStream that decodes Base64-encoded data read from another input stream.

• It provides methods for reading, skipping, marking, and resetting the stream, similar to other input streams.

• The constructor takes an existing InputStream and flags to control the decoding process using Base64 constants.

• Base64InputStream handles the decoding transparently, allowing you to read the decoded data directly.

• Common input stream operations like read(), available(), close(), mark(), reset(), and skip() are supported.
