Field Detail

dt

public final org.relaxng.datatype.Datatype dt

Datatype object that is used to test the equality.

value

public final java.lang.Object value

This expression matches this value only.

name

public final StringPair name

name of this datatype. The value of this field is not considered as significant. When two TypedStringExps share the same Datatype object, then they are unified even if they have different names.

serialVersionUID

private static final long serialVersionUID
