Method Detail

ALL

public RTerminal ALL()

JCYPHER

return all nodes, relationships and paths found in a query,

e.g. ALL()

value

public RSortable value(JcValue element)

JCYPHER

select a named (identified) element

e.g. value(n)

or an expression like value(n.property("age")) to be returned

evalPredicate

public RElement<RElement<?>> evalPredicate(Concatenator P)

JCYPHER

return the result of evaluating a Predicate Expression (true or false)

Use Factory Class P to create a Predicate Expressions

e.g. ...evalPredicate(P.valueOf(a.property("age")).GT(30))

existsPattern

public RElement<RElement<?>> existsPattern(IElement X)

JCYPHER

try to match a pattern against the graph. If a match is found return true else return false

Use Factory Class X to create a Pattern Expressions

e.g. existsPattern(X.node(n)...)

collection

public RElement<RElement<?>> collection(ICollectExpression C)

JCYPHER

return the result of a collection expression

Use Factory Class C to create a Collection Expressions

e.g. ...collection(C.COLLECT().property("name").from(nds))

collection

public RElement<RElement<?>> collection(JcCollection collection)

JCYPHER

return a collection

e.g. ...collection(p.nodes())

or ...collection(n.labels())

getReturnExpression

protected ReturnExpression getReturnExpression()
