Method Details

getAlias

@NotNull
public @NotNull String getAlias()

Specified by:

getAlias in interface Aliased

Returns:

the alias.

as

@NotNull
public @NotNull AliasedExpression as(String newAlias)

This takes the originally aliased expression and re-aliases it. Aliases are not nested.

Specified by:

as in interface Expression

Parameters:

newAlias - The new alias to use

Returns:

A new aliased, expression.

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.

asExpression

@NotNull
public @NotNull Expression asExpression()

Description copied from interface: IdentifiableElement

Transform this element into an expression

Specified by:

asExpression in interface IdentifiableElement

Returns:

this element as an expression. Will return the same instance if it is already an expression.

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}
