Constructor Detail

MemSwapUsageRecord

public MemSwapUsageRecord(long timestamp,
                          String hostname,
                          long memTotal,
                          long memUsed,
                          long memFree,
                          long swapTotal,
                          long swapUsed,
                          long swapFree)

Constructs a new MemSwapUsageRecord with the given values. If certain String values shall remain undefined, use the constant DEFAULT_VALUE.

Parameters:

timestamp - The timestamp of the measure.

hostname - The name of the host.

memTotal - The total available memory.

memUsed - The used memory.

memFree - The free memory.

swapTotal - The total available swap.

swapUsed - The used swap.

swapFree - The free swap.

MemSwapUsageRecord

public MemSwapUsageRecord(Object[] values)

This constructor converts the given array into a record. It is recommended to use the array which is the result of a call to toArray().

Parameters:

values - The values for the record.

MemSwapUsageRecord

public MemSwapUsageRecord(ByteBuffer buffer,
                          IRegistry<String> stringRegistry)
                   throws BufferUnderflowException

This constructor converts the given array into a record.

Parameters:

buffer - The bytes for the record.

Throws:

BufferUnderflowException - if buffer not sufficient

Method Detail

toArray

public Object[] toArray()

This method should deliver an array containing the content of the record. It should be possible to convert this array later into a record again.

Specified by:

toArray in interface IMonitoringRecord

Returns:

An array with the values of the record.

writeBytes

public void writeBytes(ByteBuffer buffer,
                       IRegistry<String> stringRegistry)
                throws BufferOverflowException

This method should deliver an byte array containing the content of the record. It should be possible to convert this array later into a record again.

Specified by:

writeBytes in interface IMonitoringRecord

Parameters:

buffer - The used ByteBuffer with sufficient capacity

stringRegistry - Usually the associated MonitoringController

Throws:

BufferOverflowException - if buffer not sufficient

initFromArray

@Deprecated
public final void initFromArray(Object[] values)

Deprecated. This record uses the IMonitoringRecord.Factory mechanism. Hence, this method is not implemented.

This method should initialize the record based on the given values. The array should be one of those resulting from a call to IMonitoringRecord.toArray().

Specified by:

initFromArray in interface IMonitoringRecord

Parameters:

values - The values for the record.

initFromBytes

@Deprecated
public final void initFromBytes(ByteBuffer buffer,
                                           IRegistry<String> stringRegistry)
                         throws BufferUnderflowException

Deprecated. This record uses the IMonitoringRecord.BinaryFactory mechanism. Hence, this method is not implemented.

This method should initialize the record based on the given values. The array should be one of those resulting from a call to IMonitoringRecord.writeBytes(ByteBuffer, IRegistry).

Specified by:

initFromBytes in interface IMonitoringRecord

Parameters:

buffer - The bytes for the record.

stringRegistry - The Registry storing the strings.

Throws:

BufferUnderflowException - if buffer not sufficient

getValueTypes

public Class<?>[] getValueTypes()

This method should deliver an array with the classes of the single values for the record.

Specified by:

getValueTypes in interface IMonitoringRecord

Returns:

The types of the values. This returned array should be treated readonly.

See Also:

IMonitoringRecord.toArray()

getSize

public int getSize()

This method should deliver the size of a binary representation of this record.

Specified by:

getSize in interface IMonitoringRecord

Returns:

The size.

getMemTotal

public final long getMemTotal()

Returns:

the memTotal

getMemUsed

public final long getMemUsed()

Returns:

the memUsed

getMemFree

public final long getMemFree()

Returns:

the memFree

getSwapTotal

public final long getSwapTotal()

Returns:

the swapTotal

getSwapUsed

public final long getSwapUsed()

Returns:

the swapUsed

getSwapFree

public final long getSwapFree()

Returns:

the swapFree

getTimestamp

public final long getTimestamp()

Returns:

the timestamp
