Class ArmMetricDefinition

java.lang.Object

org.arm4.arm40.transaction.ArmInterface

org.arm4.arm40.metric.ArmMetricDefinition

All Implemented Interfaces:

ArmMetricDefinition, ArmInterface

Direct Known Subclasses:

ArmMetricCounter32Definition, ArmMetricCounter64Definition, ArmMetricCounterFloat32Definition, ArmMetricGauge32Definition, ArmMetricGauge64Definition, ArmMetricGaugeFloat32Definition, ArmMetricNumericId32Definition, ArmMetricNumericId64Definition, ArmMetricString32Definition

public class ArmMetricDefinition
extends ArmInterface
implements ArmMetricDefinition

The superclass for all the metric definition interfaces. All the methods are defined in ArmMetricDefinition. The subclasses serve as markers for the data types. All the publicly accessible attributes are immutable and have a getter method for them.

The attributes are:

• The definition of the application that contains the transaction. It must not be null.
• Name. The maximum length is 127 characters. The name must not be null or zero-length.
• Units. An optional string describing the units of measurement, such as "files" or "jobs in queue". It may be null.
• Usage. Describes any additional information about the semantics of the metric. Most metrics will be classified as "general", indicating that there is no specific semantic declared. The two specific semantics are the size of the transaction, such as the number of files that were backed up, and a status that could contain data, such as an error code that describes why a transaction failed. See the field descriptions of METRIC_USE_... below for the defined values. Any negative value is also permitted; the negative range is reserved for application-specific values.
• Optional ID. An optional 16-byte ID may be associated with the identity of a metric definition. The returned value, which could be null, is the same value passed to the factory method [e.g., ArmMetricFactory.newArmMetricCounter32Definition(org.opengroup.arm40.transaction.ArmApplicationDefinition, java.lang.String, java.lang.String, short, org.opengroup.arm40.transaction.ArmID)]. The ID value is bound to a unique combination of the metric format (e.g., Counter32), name, usage, and unit properties. When provided, the ID may be used as a concise alias for the unique combination. It may be null.

This class cannot be instantiated. Objects that implement a subclass of ArmMetricDefinition are created using the newArmMetric...Definition() methods of ArmMetricFactory.
