BrotliInputStream

public BrotliInputStream(InputStream source)
                  throws IOException

Creates a InputStream wrapper that decompresses brotli data.

For byte-by-byte reading (read()) internal buffer with DEFAULT_INTERNAL_BUFFER_SIZE size is allocated and used.

Will block the thread until first kilobyte of data of source is available.

Parameters:

source - underlying data source

Throws:

IOException - in case of corrupted data or source stream problems

BrotliInputStream

public BrotliInputStream(InputStream source,
                         int byteReadBufferSize)
                  throws IOException

Creates a InputStream wrapper that decompresses brotli data.

For byte-by-byte reading (read()) internal buffer of specified size is allocated and used.

Will block the thread until first kilobyte of data of source is available.

Parameters:

source - compressed data source

byteReadBufferSize - size of internal buffer used in case of byte-by-byte reading

Throws:

IOException - in case of corrupted data or source stream problems

BrotliInputStream

public BrotliInputStream(InputStream source,
                         int byteReadBufferSize,
                         byte[] customDictionary)
                  throws IOException

Creates a InputStream wrapper that decompresses brotli data.

For byte-by-byte reading (read()) internal buffer of specified size is allocated and used.

Will block the thread until first kilobyte of data of source is available.

Parameters:

source - compressed data source

byteReadBufferSize - size of internal buffer used in case of byte-by-byte reading

customDictionary - custom dictionary data; null if not used

Throws:

IOException - in case of corrupted data or source stream problems
