Constant Field Values

m_pagesize

private long m_pagesize

The only attribute to the machine element is required.

m_stamp

private Stamp m_stamp

The time when the snapshot was taken.

m_uname

private Uname m_uname

The uname child element is mandatory.

m_specific

private MachineSpecific m_specific

This is a grouping element for the remaining machine-specific items.

Constructor Detail

Machine

public Machine()

Default constructor.

Method Detail

setPageSize

public void setPageSize(long size)

Sets the page size.

Parameters:

size - is the remote page size in byte.

getPageSize

public long getPageSize()

Obtains the page size information.

Returns:

pagesize in byte

setStamp

public void setStamp(Stamp stamp)

Sets the time stamp when the machine info was obtained.

Parameters:

stamp - is the time stamp

getStamp

public Stamp getStamp()

Obtains the time stamp information when the remote machine element was recorded.

Returns:

stamp is a time stamp

setUname

public void setUname(Uname uname)

Sets the utsname generic system information record.

Parameters:

uname - is the utsname record

getUname

public Uname getUname()

Obtains the utsname generic system information record.

Returns:

uname is the utsname record

setMachineSpecific

public void setMachineSpecific(MachineSpecific m)

Sets the machine-specific grouping element.

Parameters:

m - is the machine specific grouping element

getMachineSpecific

public MachineSpecific getMachineSpecific()

Obtains the machine-specific grouping element.

Returns:

machine

getElementName

public String getElementName()

Returns the name of the xml element corresponding to the object.

Returns:

name

toString

public void toString(Writer stream)
              throws IOException

Converts the active state into something meant for human consumption. The method will be called when recursively traversing the instance tree.

Specified by:

toString in class org.griphyn.vdl.Chimera

Parameters:

stream - is a stream opened and ready for writing. This can also be a string stream for efficient output.

Throws:

IOException - if something fishy happens to the stream.

toXML

public void toXML(Writer stream,
                  String indent,
                  String namespace)
           throws IOException

Dump the state of the current element as XML output. This function traverses all sibling classes as necessary, and converts the data into pretty-printed XML output. The stream interface should be able to handle large output efficiently.

Specified by:

toXML in class org.griphyn.vdl.Chimera

Parameters:

stream - is a stream opened and ready for writing. This can also be a string stream for efficient output.

indent - is a String of spaces used for pretty printing. The initial amount of spaces should be an empty string. The parameter is used internally for the recursive traversal. If a null value is specified, no indentation nor linefeeds will be generated.

namespace - is the XML schema namespace prefix. If neither empty nor null, each element will be prefixed with this prefix, and the root element will map the XML namespace.

Throws:

IOException - if something fishy happens to the stream.
