Method Detail

setMaxDataSize

public void setMaxDataSize(long size)

sets the maximum size in bytes of the disk cache. The actual size may be a few Mb more for suuport file. Care should be taken to not set this value too small, as the system will trash reloading data remotely, causing it to run very slow. The recommended value is somewhere in the tens of megabytes. The default is 50 megabytes. The size checking is only done when new data is added.
