Examples of EquiJoinCondition

javax.jcr.query.qom.EquiJoinCondition
org.apache.jackrabbit.core.query.jsr283.qom.EquiJoinCondition
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:
- {@link #getSelector1Name selector1} has a property named{@link #getProperty1Name property1}, and
- {@link #getSelector2Name selector2} has a property named{@link #getProperty2Name property2}, and
- the value of {@link #getProperty1Name property1} equals the value of{@link #getProperty2Name property2}
The query is invalid if:
- {@link #getSelector1Name selector1} is not the name of a selector inthe query, or
- {@link #getSelector2Name selector2} is not the name of a selector inthe query, or
- {@link #getSelector1Name selector1} is the same as{@link #getSelector2Name selector2}, or
- {@link #getProperty1Name property1} is not a syntactically valid JCRname, or
- {@link #getProperty2Name property2} is not a syntactically valid JCRname, or
- the value of {@link #getProperty1Name property1} is not the sameproperty type as the name of {@link #getProperty2Name property2}, or
- {@link #getProperty1Name property1} is a multi-valued property, or
- {@link #getProperty2Name property2} is a multi-valued property, or
- {@link #getProperty1Name property1} is a BINARY property, or
- {@link #getProperty2Name property2} is a BINARY property.

org.jboss.dna.graph.query.model.EquiJoinCondition
A join condition that tests whether a property on a node is equal to a property on another node. A node-tuple satisfies the constraint only if:
- the {@code selector1Name} node has a property named {@code property1Name}, and
- the {@code selector2Name} node has a property named {@code property2Name}, and
- the value of property {@code property1Name} is equal to the value of property {@code property2Name}
org.modeshape.jcr.query.model.EquiJoinCondition
A join condition that tests whether a property on a node is equal to a property on another node. A node-tuple satisfies the constraint only if:
- the {@code selector1Name} node has a property named {@code property1Name}, and
- the {@code selector2Name} node has a property named {@code property2Name}, and
- the value of property {@code property1Name} is equal to the value of property {@code property2Name}
