XAttribute (OpenXES)

All Superinterfaces:

java.lang.Cloneable, java.lang.Comparable<XAttribute>, java.io.Serializable, XAttributable

All Known Subinterfaces:

XAttributeBoolean, XAttributeCollection, XAttributeContainer, XAttributeContinuous, XAttributeDiscrete, XAttributeID, XAttributeList, XAttributeLiteral, XAttributeTimestamp

All Known Implementing Classes:

XAttributeBooleanImpl, XAttributeCollectionImpl, XAttributeContainerImpl, XAttributeContinuousImpl, XAttributeDiscreteImpl, XAttributeIDImpl, XAttributeImpl, XAttributeListImpl, XAttributeLiteralImpl, XAttributeTimestampImpl
```
public interface XAttribute
extends XAttributable, java.lang.Cloneable, java.lang.Comparable<XAttribute>, java.io.Serializable
```
This interface defines attributes used for describing meta-information about event log hierarchy elements. Attributes have a name (i.e., a key), which is string-based. The value of an attribute is strongly typed, and can be accessed and modified via sub-interface methods specified by type. Attributes may further be defined by an extension, which makes it possible to assign semantic meaning to them within a specific domain.
