public static final Asterisk INSTANCE

The single instance of the *.

Method Details

asString

@NotNull
public @NotNull String asString()

Description copied from interface: Literal

The string representation should be designed in such a way the a renderer can use it correctly in the given context of the literal, i.e. a literal containing a string should quote that string and escape all reserved characters.

Specified by:

asString in interface Literal<String>

Returns:

A string representation to be used literally in a cypher statement.

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.

getContent

public final String getContent()

Returns:

The content of this literal, may 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}
