Constructor Summary

Constructors

Modifier	Constructor	Description
	TemplateModelException()	Constructs a TemplateModelException with no specified detail message.
	TemplateModelException(Exception cause)	The same as TemplateModelException(Throwable); it's exists only for binary backward-compatibility.
	TemplateModelException(String description)	Constructs a TemplateModelException with the specified detail message.
	TemplateModelException(String description, boolean replaceWithCause, Throwable cause)	Constructs a TemplateModelException with both a description of the error that occurred and the underlying Exception that caused this exception to be raised.
	TemplateModelException(String description, Exception cause)	The same as TemplateModelException(String, Throwable); it's exists only for binary backward-compatibility.
	TemplateModelException(String description, Throwable cause)	Same as TemplateModelException(String, boolean, Throwable) with false replaceWithCause argument.
	TemplateModelException(Throwable cause)	Constructs a TemplateModelException with the given underlying Exception, but no detail message.
protected	TemplateModelException(Throwable cause, Environment env, freemarker.core._ErrorDescriptionBuilder descriptionBuilder, boolean preventAmbiguity)	Don't use this; this is to be used internally by FreeMarker.
protected	TemplateModelException(Throwable cause, Environment env, String description, boolean preventAmbiguity)	Don't use this; this is to be used internally by FreeMarker.

Method Summary

Modifier and Type	Method	Description
boolean	getReplaceWithCause()	Indicates that the cause exception should be thrown instead of this exception; it was only wrapped into this exception due to API constraints.

Constructor Details

TemplateModelException

public TemplateModelException()

Constructs a TemplateModelException with no specified detail message.

TemplateModelException

public TemplateModelException(String description)

Constructs a TemplateModelException with the specified detail message.

Parameters:

description - the detail message.

TemplateModelException

public TemplateModelException(Exception cause)

The same as TemplateModelException(Throwable); it's exists only for binary backward-compatibility.

TemplateModelException

public TemplateModelException(Throwable cause)

Constructs a TemplateModelException with the given underlying Exception, but no detail message.

Parameters:

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

TemplateModelException

public TemplateModelException(String description,
 Exception cause)

The same as TemplateModelException(String, Throwable); it's exists only for binary backward-compatibility.

TemplateModelException

public TemplateModelException(String description,
 Throwable cause)

Same as TemplateModelException(String, boolean, Throwable) with false replaceWithCause argument.

TemplateModelException

public TemplateModelException(String description,
 boolean replaceWithCause,
 Throwable cause)

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

Parameters:

description - the description of the error that occurred

replaceWithCause - See getReplaceWithCause(); usually false, unless you are forced to wrap TemplateException into a TemplateModelException merely due to API constraints.

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

Since:

2.3.28

TemplateModelException

protected TemplateModelException(Throwable cause,
 Environment env,
 String description,
 boolean preventAmbiguity)

Don't use this; this is to be used internally by FreeMarker.

Parameters:

preventAmbiguity - its value is ignored; it's only to prevent constructor selection ambiguities for backward-compatibility

TemplateModelException

protected TemplateModelException(Throwable cause,
 Environment env,
 freemarker.core._ErrorDescriptionBuilder descriptionBuilder,
 boolean preventAmbiguity)

Don't use this; this is to be used internally by FreeMarker.

Parameters:

preventAmbiguity - its value is ignored; it's only to prevent constructor selection ambiguities for backward-compatibility

Method Details

getReplaceWithCause

public boolean getReplaceWithCause()

Indicates that the cause exception should be thrown instead of this exception; it was only wrapped into this exception due to API constraints. Such unwanted wrapping typically occurs when you are only allowed to throw TemplateModelException, but the exception to propagate is a more generic TemplateException. The error handler mechanism of FreeMarker will replace the exception with its Throwable.getCause() when it has bubbled up to a place where that constraint doesn't apply anymore.

Since:

2.3.28
