Constructor Detail

MemoryUsageImpl

public MemoryUsageImpl(long committed,
                       long max,
                       long init,

Method Detail

getCommitted

public long getCommitted()

Description copied from interface: MemoryUsage

Returns the amount of memory in bytes that is committed for the Java virtual machine to use.

Specified by:

getCommitted in interface MemoryUsage

Returns:

the amount of committed memory in bytes.

getMax

public long getMax()

Description copied from interface: MemoryUsage

Returns the maximum amount of memory in bytes that can be used for memory management. This method returns -1 if the maximum memory size is undefined. This amount of memory is not guaranteed to be available for memory management if it is greater than the amount of committed memory. The Java virtual machine may fail to allocate memory even if the amount of used memory does not exceed this maximum size.

Specified by:

getMax in interface MemoryUsage

Returns:

the maximum amount of memory in bytes; -1 if undefined.

getInit

public long getInit()

Description copied from interface: MemoryUsage

Returns the amount of memory in bytes that the Java virtual machine initially requests from the operating system for memory management. This method returns -1 if the initial memory size is undefined.

Specified by:

getInit in interface MemoryUsage

Returns:

the initial size of memory in bytes; -1 if undefined.

getUsed

public long getUsed()

Description copied from interface: MemoryUsage

Returns the amount of used memory in bytes.

Specified by:

getUsed in interface MemoryUsage

Returns:

the amount of used memory in bytes.
