-
collect ()
causes a garbage collection to occur.
-
pack ()
shrinks the heap as much as possible so that other processes can use available RAM.
-
setMessages b
controls whether diagnostic messages are printed at the beginning and end of each garbage collection. It is the same as the gc-messages runtime system option.
-
setSummary b
controls whether a summary of garbage collection statistics is printed upon termination of the program. It is the same as the gc-summary runtime system option.
-
unpack ()
resizes a packed heap to the size desired by the runtime.
-
Statistics.bytesAllocated ()
returns bytes allocated (as of the most recent garbage collection).
-
Statistics.lastBytesLive ()
returns bytes live (as of the most recent garbage collection).
-
Statistics.numCopyingGCs ()
returns number of (major) copying garbage collections performed (as of the most recent garbage collection).
-
Statistics.numMarkCompactGCs ()
returns number of (major) mark-compact garbage collections performed (as of the most recent garbage collection).
-
Statistics.numMinorGCs ()
returns number of minor garbage collections performed (as of the most recent garbage collection).
-
Statistics.maxBytesLive ()
returns maximum bytes live (as of the most recent garbage collection).
