Method Detail

lookup

public static MemoryProfiler lookup()

getMinMemorySize

public long getMinMemorySize()

setMinMemorySize

public void setMinMemorySize(long minMemorySize)

getMinMemoryPercentage

public float getMinMemoryPercentage()

setMinMemoryPercentage

public void setMinMemoryPercentage(float minMemoryPercentage)

isLowMemory

public boolean isLowMemory()

getFreeMemoryInBytes

public long getFreeMemoryInBytes()

Returns the amount of free memory in the Java Virtual Machine. Calling the gc method may result in increasing the value returned by freeMemory.

Returns:

an approximation to the total amount of memory currently available for future allocated objects, measured in bytes.

getTotalMemoryInBytes

public long getTotalMemoryInBytes()

Returns the total amount of memory in the Java virtual machine. The value returned by this method may vary over time, depending on the host environment.

Note that the amount of memory required to hold an object of any given type may be implementation-dependent.

Returns:

the total amount of memory currently available for current and future objects, measured in bytes.

freeMemory

public MemoryProfiler freeMemory()

freeEvenMoreMemory

protected void freeEvenMoreMemory()

getMemoryUsedInBytes

public long getMemoryUsedInBytes()

formatSize

public static String formatSize(long bytes)
