1.125.2 ObjectMemory class: builtins

abort

Quit the Smalltalk environment, dumping core.

addressOf: anObject

Returns the address of the actual object that anObject references. Note that, with the exception of fixed objects this address is only valid until the next garbage collection; thus it’s pretty risky to count on the address returned by this method for very long.

addressOfOOP: anObject

Returns the address of the OOP (object table slot) for anObject. The address is an Integer and will not change over time (i.e. is immune from garbage collector action) except if the virtual machine is stopped and restarted.

bigObjectThreshold

Answer the smallest size for objects that are allocated outside the main heap in the hope of providing more locality of reference between small objects.

bigObjectThreshold: bytes

Set the smallest size for objects that are allocated outside the main heap in the hope of providing more locality of reference between small objects. bytes must be a positive SmallInteger.

compact

Force a full garbage collection, including compaction of oldspace

finishIncrementalGC

Do a step in the incremental garbage collection.

gcMessage

Answer whether messages indicating that garbage collection is taking place are printed on stdout

gcMessage: aBoolean

Set whether messages indicating that garbage collection is taking place are printed on stdout

globalGarbageCollect

Force a full garbage collection

growThresholdPercent

Answer the percentage of the amount of memory used by the system grows which has to be full for the system to allocate more memory

growThresholdPercent: growPercent

Set the percentage of the amount of memory used by the system grows which has to be full for the system to allocate more memory

growTo: numBytes

Grow the amount of memory used by the system grows to numBytes.

incrementalGCStep

Do a step in the incremental garbage collection.

quit

Quit the Smalltalk environment. Whether files are closed and other similar cleanup occurs depends on the platform

quit: exitStatus

Quit the Smalltalk environment, passing the exitStatus integer to the OS. Files are closed and other similar cleanups occur.

scavenge

Force a minor garbage collection

smoothingFactor

Answer the factor (between 0 and 1) used to smooth the statistics provided by the virtual machine about memory handling. 0 disables updating the averages, 1 disables the smoothing (the statistics return the last value).

smoothingFactor: rate

Set the factor (between 0 and 1) used to smooth the statistics provided by the virtual machine about memory handling. 0 disables updating the averages, 1 disables the smoothing (the statistics return the last value).

spaceGrowRate

Answer the rate with which the amount of memory used by the system grows

spaceGrowRate: rate

Set the rate with which the amount of memory used by the system grows
