API Note

This class implements AutoCloseable to facilitate its usage with try-with-resources statement. The close() method simply calls end().

The following code fragment demonstrates a trivial compression and decompression of a string using Deflater and Inflater.

// Encode a String into bytes
String inputString = "blahblahblah€€";
byte[] input = inputString.getBytes(StandardCharsets.UTF_8);

// Compress the bytes
ByteArrayOutputStream compressedBaos = new ByteArrayOutputStream();
try (Deflater compressor = new Deflater()) {
    compressor.setInput(input);
    // Let the compressor know that the complete input
    // has been made available
    compressor.finish();
    // Keep compressing the input till the compressor
    // is finished compressing
    while (!compressor.finished()) {
        // Use some reasonable size for the temporary buffer
        // based on the data being compressed
        byte[] tmpBuffer = new byte[100];
        int numCompressed = compressor.deflate(tmpBuffer);
        // Copy over the compressed bytes from the temporary
        // buffer into the final byte array
        compressedBaos.write(tmpBuffer, 0, numCompressed);
    }
}

// Decompress the bytes
ByteArrayOutputStream decompressedBaos = new ByteArrayOutputStream();
try (Inflater decompressor = new Inflater()) {
    byte[] compressed = compressedBaos.toByteArray();
    decompressor.setInput(compressed, 0, compressed.length);
    while (!decompressor.finished()) {
        // Use some reasonable size for the temporary buffer,
        // based on the data being decompressed; in this example,
        // we use a small buffer size
        byte[] tmpBuffer = new byte[100];
        int numDecompressed = 0;
        try {

        // buffer into the final byte array
        decompressedBaos.write(tmpBuffer, 0, numDecompressed);
    }

// Decode the bytes into a String

        // buffer into the final byte array
        compressedBaos.write(tmpBuffer, 0, numCompressed);
    }
}

// Decompress the bytes
ByteArrayOutputStream decompressedBaos = new ByteArrayOutputStream();
try (Inflater decompressor = new Inflater()) {
    byte[] compressed = compressedBaos.toByteArray();

Constructor Detail

Inflater	back to summary
public Inflater(boolean nowrap) Creates a new decompressor. If the parameter 'nowrap' is true then the ZLIB header and checksum fields will not be used. This provides compatibility with the compression format used by both GZIP and PKZIP. Note When using the 'nowrap' option it is also necessary to provide an extra "dummy" byte as input. This is required by the ZLIB native library in order to support certain optimizations. Parameters nowrap:boolean if true then support GZIP compatible compression Annotations @SuppressWarnings:this-escape

public int inflate(byte[] output, int off, int len) throws DataFormatException Uncompresses bytes into specified buffer. Returns actual number of bytes uncompressed. A return value of 0 indicates that needsInput() or needsDictionary() should be called in order to determine if more input data or a preset dictionary is required. In the latter case, getAdler() can be used to get the Adler-32 value of the dictionary required. If the `setInput(ByteBuffer)` method was called to provide a buffer for input, the input buffer's position will be advanced by the number of bytes consumed by this operation, even in the event that a `DataFormatException` is thrown. The remaining byte count will be reduced by the number of consumed input bytes. If the `setInput(ByteBuffer)` method was called to provide a buffer for input, the input buffer's position will be advanced the number of consumed bytes. These byte totals, as well as the total bytes read and the total bytes written values, will be updated even in the event that a `DataFormatException` is thrown to reflect the amount of data consumed and produced before the exception occurred.

public void setInput(ByteBuffer input)

Sets input data for decompression.

One of the setInput() methods should be called whenever needsInput() returns true indicating that more input data is required.

The given buffer's position will be advanced as inflate operations are performed, up to the buffer's limit. The input buffer may be modified (refilled) between inflate operations; doing so is equivalent to creating a new buffer and setting it with this method.

Modifying the input buffer's contents, position, or limit concurrently with an inflate operation will result in undefined behavior, which may include incorrect operation results or operation failure.
