Memory refers to the state information of a computing system, as it is kept active in some physical structure. The term "memory" is used for the information in physical systems which are fast (ie. RAM), as a distinction from physical systems which are slow to access (ie. data storage). By design, the term "memory" refers to temporary state devices, whereas the term "storage" is reserved for permanent data.

Method Detail

getTotal

long getTotal()

The amount of actual physical memory, in bytes.

Returns:

Total number of bytes.

getAvailable

long getAvailable()

The amount of physical memory currently available, in bytes.

Returns:

Available number of bytes.

getSwapTotal

long getSwapTotal()

The current size of the paging/swap file(s), in bytes. If the paging/swap file can be extended, this is a soft limit.

Returns:

Total swap in bytes.

getSwapUsed

long getSwapUsed()

The current memory committed to the paging/swap file(s), in bytes

Returns:

Swap used in bytes
