public GZipCompression()

Method Detail

isCompressed

public boolean isCompressed(byte[] bytes)
                     throws java.io.IOException

Determines if a byte array is compressed. The java.util.zip GZip implementaiton does not expose the GZip header so it is difficult to determine if a string is compressed.

Specified by:

isCompressed in interface CompressionStrategy

---

readByte

private int readByte(java.io.InputStream in)
              throws java.io.IOException

---

compressByteArray

public byte[] compressByteArray(byte[] bytes)
                         throws java.io.IOException

Used for compressing a byte array into a new byte array using GZIP

Specified by:

compressByteArray in interface CompressionStrategy

---

uncompressByteArray

public byte[] uncompressByteArray(byte[] bytes)
                           throws java.io.IOException

Used for uncompressing a byte array into a uncompressed byte array using GZIP

Specified by:

uncompressByteArray in interface CompressionStrategy
