Since:

2021.2.3

and

@NotNull
@Contract(pure=true)
public @NotNull MapProjection and(Object... content)

Adds additional content. The current projection is left unchanged and a new one is returned.

accept

public void accept(Visitor visitor)

Description copied from interface: Visitable

Accept a Visitor visiting this Visitable and its nested Visitables if applicable.

Specified by:

accept in interface Visitable

Parameters:

visitor - the visitor to notify, must not be null.

toString

public String toString()

Description copied from interface: Visitable

Most visitables will render themselves into a Cypher fragment preceded with the actual classname. The representation however is not cached - in contrast to the ones for full statements. Using toString is recommended for debugging purposes mainly, and not for production use.

The concrete classname has been prepended to help debugging and actually to discourage using fragments to build queries without explicitly rendering them, either as statement or going through the renderer on purpose.

Specified by:

toString in interface Visitable

Overrides:

toString in class Object

Returns:

A string representation of this visitable formatted as Classname{cypher=value}
