Creates an instance of TECLMemoryStream.
constructor Create(Password: String; CompressLevel: TECLCompressionLevel = eclNone; CustomHeaderSize: Integer = 0);
Call Create to instantiate a compression/decompression stream for reading from or writing to the memory.
A Password parameter value different from default blank string indicates that the data is encrypted by this password.
CompressLevel indicates the level of compression to be used for the created stream.
Specify CustomHeaderSize parameter to set the number of bytes in the custom not compressed header. This custom header could be used to store user information that will not be compressed or encrypted. See also help for CustomHeaderSize property.
