LocalMemoryStatsImpl

public LocalMemoryStatsImpl()

LocalMemoryStatsImpl

public LocalMemoryStatsImpl(MemoryStats memoryStats)

Method Detail

getTotalPhysical

public long getTotalPhysical()

Description copied from interface: MemoryStats

Returns total physical memory available in OS.

Specified by:

getTotalPhysical in interface MemoryStats

Returns:

total physical memory in bytes.

setTotalPhysical

public void setTotalPhysical(long totalPhysical)

getFreePhysical

public long getFreePhysical()

Description copied from interface: MemoryStats

Returns free physical memory available in OS.

Some operating systems have cached memory regions in which they store hot cached resources like files. Cached memory is used for allocations when required. So although this cached region is assumed as free, operating systems generally report this region as used not free.

Specified by:

getFreePhysical in interface MemoryStats

Returns:

free physical memory in bytes.

setFreePhysical

public void setFreePhysical(long freePhysical)

getMaxNativeMemory

public long getMaxNativeMemory()

Description copied from interface: MemoryStats

Returns the maximum amount of native memory that current HazelcastInstance will attempt to use in bytes.

Specified by:

getMaxNativeMemory in interface MemoryStats

Returns:

the maximum amount of native memory in bytes.

setMaxNativeMemory

public void setMaxNativeMemory(long maxNativeMemory)

getCommittedNativeMemory

public long getCommittedNativeMemory()

Description copied from interface: MemoryStats

Returns the amount of native memory in bytes that is committed for current HazelcastInstance to use.

Specified by:

getCommittedNativeMemory in interface MemoryStats

Returns:

the amount of committed native memory in bytes.

setCommittedNativeMemory

public void setCommittedNativeMemory(long allocated)

getUsedNativeMemory

public long getUsedNativeMemory()

Description copied from interface: MemoryStats

Returns the amount of used native memory in current HazelcastInstance in bytes.

Specified by:

getUsedNativeMemory in interface MemoryStats

Returns:

the amount of used native memory in bytes

setUsedNativeMemory

public void setUsedNativeMemory(long used)

getFreeNativeMemory

public long getFreeNativeMemory()

Description copied from interface: MemoryStats

Returns the amount of free native memory in current HazelcastInstance in bytes.

Specified by:

getFreeNativeMemory in interface MemoryStats

Returns:

the amount of free native memory in bytes

setFreeNativeMemory

public void setFreeNativeMemory(long freeNativeMemory)

getMaxHeap

public long getMaxHeap()

Description copied from interface: MemoryStats

Returns the maximum amount of memory that the JVM will attempt to use in bytes.

Specified by:

getMaxHeap in interface MemoryStats

Returns:

the maximum amount of memory in bytes.

Runtime.maxMemory()

getCommittedHeap

public long getCommittedHeap()

Description copied from interface: MemoryStats

Runtime.totalMemory(), MemoryUsage.getCommitted()

getUsedHeap

public long getUsedHeap()

Description copied from interface: MemoryStats

Returns the amount of used memory in the JVM in bytes.

Specified by:

getUsedHeap in interface MemoryStats

Returns:

the amount of used memory in bytes
