Constructor Detail

EmptyRecord

public EmptyRecord()

Creates a new instance of this class using the given parameters.

EmptyRecord

public EmptyRecord(java.lang.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.

EmptyRecord

protected EmptyRecord(java.lang.Object[] values,
                      java.lang.Class<?>[] valueTypes)

This constructor uses the given array to initialize the fields of this record.

Parameters:

values - The values for the record.

valueTypes - The types of the elements in the first array.

EmptyRecord

public EmptyRecord(java.nio.ByteBuffer buffer,
                   IRegistry<java.lang.String> stringRegistry)
            throws java.nio.BufferUnderflowException

This constructor converts the given array into a record.

Parameters:

buffer - The bytes for the record.

Throws:

java.nio.BufferUnderflowException - if buffer not sufficient

Method Detail

toArray

public java.lang.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.

registerStrings

public void registerStrings(IRegistry<java.lang.String> stringRegistry)

Registers the string attributes of the record at the given stringRegistry.

Specified by:

registerStrings in interface IMonitoringRecord

Overrides:

registerStrings in class AbstractMonitoringRecord

writeBytes

public void writeBytes(java.nio.ByteBuffer buffer,
                       IRegistry<java.lang.String> stringRegistry)
                throws java.nio.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:

java.nio.BufferOverflowException - if buffer not sufficient

getValueTypes

public java.lang.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.

initFromArray

@Deprecated
public void initFromArray(java.lang.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 void initFromBytes(java.nio.ByteBuffer buffer,
                                     IRegistry<java.lang.String> stringRegistry)
                   throws java.nio.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:

java.nio.BufferUnderflowException - if buffer not sufficient
