public SystemMemoryOshi()

Method Details

getPhysicalTotal

@Parameter
public abstract long getPhysicalTotal()

The amount of actual physical memory, in bytes.

Returns:

Total number of bytes.

getSwapTotal

@Parameter
public abstract 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.

getPageSize

@Parameter
public abstract long getPageSize()

The number of bytes in a memory page

Returns:

Page size in bytes.

traverse

public final void traverse(PropertyVisitor visitor)

Description copied from interface: PropertySet

Traverse this property set and output the property key/values to the given visitor.

Callers should typically prefer to call PropertyVisitor.visitProperties(PropertySet), as the inversion of logic allows the visitor (the more stateful object) to potentially perform initialization logic and traverse more efficiently.

Specified by:

traverse in interface PropertySet

Parameters:

visitor - the visitor
