PDL::DiskCache Description

Non-memory-resident array object PDL::DiskCache is a non-memory-resident array Perl object.SYNOPSISNON-OO: use PDL::DiskCache; tie @a,'PDL::DiskCache', @files, \%options; imag $a;OO: use PDL::DiskCache; $a = diskcache(@files,\%options); imag $a->;or use PDL::DiskCache; $a = new PDL::DiskCache(@files,\%options); imag $a->;@files an array ref containing a list of file names\%options a hash ref containing options for the PDL::DiskCache object (see "TIEARRAY" below for details)A PDL::DiskCache object is a perl "tied array" that is useful for operations where you have to look at a large collection of PDLs one or a few at a time (such as tracking features through an image sequence). You can write prototype code that uses a perl list of a few PDLs, then scale up to to millions of PDLs simply by handing the prototype code a DiskCache tied array instead of a native perl array. The individual PDLs are stored on disk and a few of them are swapped into memory on a FIFO basis. You can set whether the data are read-only or writeable. Requirements: · Perl
