Twig_Error

class Twig_Error extends Exception

Twig base exception.

This exception class and its children must only be used when
an error occurs during the loading of a template, when a syntax error
is detected in a template, or when rendering a template. Other
errors must use regular PHP exception classes (like when the template
cache directory is not writable for instance).

To help debugging template issues, this class tracks the original template
name and line where the error occurred.

Whenever possible, you must set these information (original template name
and line number) yourself by passing them to the constructor. If some or all
these information are not available from where you throw the exception, then
this class will guess them automatically (when the line number is set to -1
and/or the filename is set to null). As this is a costly operation, this
can be disabled by passing false for both the filename and the line number
when creating a new instance of this class.
