Interface EquiJoinCondition

All Superinterfaces:

JoinCondition

All Known Implementing Classes:

EquiJoinConditionImpl

public interface EquiJoinCondition
extends JoinCondition

Tests whether the value of a property in a first selector is equal to the value of a property in a second selector.

A node-tuple satisfies the constraint only if:

• selector1 has a property named property1, and
• selector2 has a property named property2, and
• the value of property1 equals the value of property2

The query is invalid if:

• selector1 is not the name of a selector in the query, or
• selector2 is not the name of a selector in the query, or
• selector1 is the same as selector2, or
• property1 is not a syntactically valid JCR name, or
• property2 is not a syntactically valid JCR name, or
• the value of property1 is not the same property type as the name of property2, or
• property1 is a multi-valued property, or
• property2 is a multi-valued property, or
• property1 is a BINARY property, or
• property2 is a BINARY property.

Since:

JCR 2.0
