Constructor Details

TemplateException

public TemplateException(Environment env)

Constructs a TemplateException with no specified detail message or underlying cause.

TemplateException

public TemplateException(String description,
 Environment env)

Constructs a TemplateException with the given detail message, but no underlying cause exception.

Parameters:

description - the description of the error that occurred

Parameters:

cause - the underlying Exception that caused this exception to be raised

 Exception cause,
 Environment env)

Constructs a TemplateException with both a description of the error that occurred and the underlying Exception that caused this exception to be raised.

Method Details

getCauseException

public Exception getCauseException()

Returns the underlying exception that caused this exception to be generated.

Note:
avoided calling it getCause to avoid name clash with JDK 1.4 method. This would be problematic because the JDK 1.4 method returns a Throwable rather than an Exception.

Returns:

the underlying Exception, if any, that caused this exception to be raised

getFTLInstructionStack

public String getFTLInstructionStack()

Returns the quote of the problematic FTL instruction and the FTL stack strace. As of FreeMarker 2.4, we provide access to the FTL instruction stack so you might prefer to use getFTLStack() and format the items in list yourself.

• getFTLStack()

getFTLStack

public List<freemarker.core.parser.TemplateLocation> getFTLStack()

Returns:

the FTL call stack (starting with current element)

getEnvironment

public Environment getEnvironment()

Returns:

the execution environment in which the exception occurred

printStackTrace

public void printStackTrace(PrintStream ps)

Overrides:

printStackTrace in class Throwable

printStackTrace

public void printStackTrace(PrintWriter pw)

Overrides:

printStackTrace in class Throwable
