Helper class used by code generated by the require
macro.
Require that a boolean condition about an argument passed to a method, function, or constructor,
and described in the given clue
, is true.
Require that a boolean condition about an argument passed to a method, function, or constructor,
and described in the given clue
, is true.
If the condition is true
, this method returns normally.
Else, it throws IllegalArgumentException
with the
String
obtained by invoking toString
on the
specified clue
and appending that to the macro-generated
error message as the exception's detail message.
the boolean condition to check as requirement
an objects whose toString
method returns a message to include in a failure report.
if the condition is false
.
if message
is null

Require that a boolean condition is true about an argument passed to a method, function, or constructor.
Require that a boolean condition is true about an argument passed to a method, function, or constructor.
If the condition is true
, this method returns normally.
Else, it throws IllegalArgumentException

Require that all passed arguments are non-null.
Require that all passed arguments are non-null.
If none of the passed arguments are null
, this method returns normally.
Else, it throws NullPointerException
