org.apache.jackrabbit.core.query.jsr283.qom.PropertyValue
Evaluates to the value (or values, if multi-valued) of a property.
If, for a node-tuple, the {@link #getSelectorName selector} node does nothave a property named {@link #getPropertyName property}, the operand evaluates to null.
The query is invalid if:
- {@link #getSelectorName selector} is not the name of a selector in thequery, or
- {@link #getPropertyName property} is not a syntactically valid JCRname.
@since JCR 2.0
