java.lang.Object

com.emc.atmos.api.encryption.CompressionConfig

public class CompressionConfig
extends java.lang.Object

Contains the configuration for compression transformation in the Atmos client. Note that while LZMA compression produces high compression ratios it requires large amounts of RAM. In particular, even level 5 can exceed the default Java heap size.
