Method Detail

returning

@NotNull
@CheckReturnValue
default StatementBuilder.OngoingReadingAndReturn returning(java.lang.String... variables)

Creates the RETURN clause. All variables passed via variables must be valid symbolic names. Expression.property(String...) must be used to return single properties.

Parameters:

variables - The named things to return

Returns:

A build step with a defined list of things to return.

returning

@NotNull
@CheckReturnValue
default StatementBuilder.OngoingReadingAndReturn returning(Named... variables)

Creates the RETURN clause.

Parameters:

variables - The named things to return

Returns:

A build step with a defined list of things to return.

returning

@NotNull
@CheckReturnValue
StatementBuilder.OngoingReadingAndReturn returning(Expression... expressions)

Create a match that returns one or more expressions.

Parameters:

expressions - The expressions to be returned. Must not be null and be at least one expression.

Returns:

A match that can be build now

returning

@NotNull
@CheckReturnValue
StatementBuilder.OngoingReadingAndReturn returning(java.util.Collection<Expression> expressions)

Create a match that returns one or more expressions.

Parameters:

expressions - The expressions to be returned. Must not be null and be at least one expression.

Returns:

A match that can be build now

returningDistinct

@NotNull
@CheckReturnValue
default StatementBuilder.OngoingReadingAndReturn returningDistinct(java.lang.String... variables)

Creates a RETURN clause containing the DISTINCT keyword. All variables passed via variables must be valid symbolic names. Expression.property(String...) must be used to return single properties.

Parameters:

variables - The named things to return

Returns:

A build step with a defined list of things to return.

returningDistinct

@NotNull
@CheckReturnValue
default StatementBuilder.OngoingReadingAndReturn returningDistinct(Named... variables)

Creates a RETURN clause containing the DISTINCT keyword.

Parameters:

variables - The named things to return

Returns:

A build step with a defined list of things to return.

returningDistinct

@NotNull
@CheckReturnValue
StatementBuilder.OngoingReadingAndReturn returningDistinct(Expression... expressions)

Creates a RETURN clause returning the distinct set of one or more expressions.

Parameters:

expressions - The expressions to be returned. Must not be null and be at least one expression.

Returns:

A match that can be build now

returningDistinct

@NotNull
@CheckReturnValue
StatementBuilder.OngoingReadingAndReturn returningDistinct(java.util.Collection<Expression> expressions)

Creates a RETURN clause returning the distinct set of one or more expressions.

Parameters:

expressions - The expressions to be returned. Must not be null and be at least one expression.

Returns:

A match that can be build now

returningRaw

@NotNull
@CheckReturnValue
StatementBuilder.OngoingReadingAndReturn returningRaw(Expression rawExpression)

Creates a RETURN clause from a raw Cypher expression created via Cypher.raw(String, Object...). The expression maybe aliased but it must resolve to a raw element

Parameters:

rawExpression - Must be a plain raw or an aliased raw expression. To eventually render as valid Cypher, it must contain the RETURN keyword.

Returns:

A match that can be build now
