Method Detail

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.

getParameters

public java.util.Map<java.lang.String,java.lang.Object> getParameters()

Description copied from interface: Statement

After a statement has been build, all parameters that have been added to the statement can be retrieved through this method. The result will only contain parameters with a defined value. If you are interested in all parameter names, use Statement.getParameterNames().

The map can be used for example as an argument with various methods on the Neo4j Java Driver that allow the execution of parameterized queries.

This method is threadsafe

Specified by:

getParameters in interface Statement

Returns:

A map of all parameters with a bound value.

getParameterNames

public java.util.Set<java.lang.String> getParameterNames()

Description copied from interface: Statement

After the statement has been build, this method returns a list of all parameter names used, regardless whether a value was bound to the parameter o not.

This method is threadsafe

Specified by:

getParameterNames in interface Statement

Returns:

A set of parameter names being used.

getCypher

public java.lang.String getCypher()

Description copied from interface: Statement

This method uses the default renderer to create a String representation of this statement. The generated Cypher will use escaped literals and correct placeholders like $param for parameters. The placeholders for parameters can be retrieved via Statement.getParameterNames(). Bounded values for paramters can be retrieved via Statement.getParameters().

This method is threadsafe

Specified by:

getCypher in interface Statement

Returns:

A valid Cypher statement
