Flush the data (but do not unlock).
Reimplemented from casacore::LatticeBase.

Reimplemented from casacore::LatticeBase.
virtual void casacore::LCPagedMask::resync | ( | ) | [virtual] |
Resynchronize the PagedArray object with the lattice file.
This function is only useful if no read-locking is used, ie. if the table lock option is UserNoReadLocking or AutoNoReadLocking. In that cases the table system does not acquire a read-lock, thus does not synchronize itself automatically.

virtual void casacore::LCPagedMask::setCacheSizeInTiles | ( | uInt | howManyTiles | ) | [virtual] |
Set the actual cache size for this Array to be be big enough for the indicated number of tiles.
This cache is not shared with PagedArrays in other rows and is always clipped to be less than the maximum value set using the setMaximumCacheSize member function. tiles. Tiles are cached using a first in first out algorithm.
Reimplemented from casacore::LatticeBase.
virtual void casacore::LCPagedMask::setMaximumCacheSize | ( | uInt | howManyPixels | ) | [virtual] |
