Abstract
A system and method of squeezing slabs of memory empty are provided. A slab is a block of allocated memory space that is dedicated to holding one type of data. When it is determined that a slab of memory is to be squeezed empty, no object may be allocated from the slab. That is, new data is precluded from being placed in any unused space of the slab. Further, data is also precluded from being placed in any space in the slab that becomes unused anytime thereafter. When the slab becomes empty, the slab is de-allocated.
Claims21
A method of squeezing slabs empty, a slab being a block of allocated memory space, the method comprising the steps of:
- determining whether a slab is to be squeezed empty;
- and
- precluding, if the slab is to be squeezed empty, data from being placed in any unused space of the slab.
A computer program product on a computer readable medium for squeezing slabs empty, a slab being a block of allocated memory space, the computer program product comprising:
- code means for determining whether a slab is to be squeezed empty;
- and
- code means for precluding, if the slab is to be squeezed empty, data from being placed in any unused space of the slab.
A system for squeezing slabs empty, a slab being a block of allocated memory space, the system comprising:
- at least one storage device for storing code data;
- and
- at least one processor for processing the code data to determine whether a slab is to be squeezed empty, and to preclude, if the slab is to be squeezed empty, data from being placed in any unused space of the slab.
