cdflib.setCacheSize

Specify number of dotCDF cache buffers

Syntax

cdflib.setCacheSize(cdfId,numBuffers)


Description

cdflib.setCacheSize(cdfId,numBuffers) specifies the number of cache buffers the CDF library uses for an open dotCDF file. A dotCDF file is a file with the .cdf file extension.

cdfId identifies an open CDF file. numBuffers is a numeric value that specifies the number of buffers.

For information about cache schemes, see the CDF User's Guide.

Examples

Create a CDF file and set the cache size. To run this example, you must have write permission in your current folder.

cdfId = cdflib.create("your_file.cdf");

% Get the default cache size
numBuf = cdflib.getCacheSize(cdfId)

numBuf =

   300

% Specify a cache size
cdflib.setCacheSize(cdfId,150)

% Check the cache size again
numBuf = cdflib.getCacheSize(cdfId)

numBuf =

   150

% Clean up
cdflib.delete(cdfId)
clear cdfId
