parseBooleanAttribute

public static Boolean parseBooleanAttribute(org.thymeleaf.Arguments arguments,
                            org.thymeleaf.dom.Element element,

Parses the value of an attribute as a Boolean.

Parameters:

arguments - Thymeleaf Arguments

element - The element in which an attribute is to be parsed.

attributeName - The attribute name for which the value is to be parsed.

Returns:

A Boolean which is evaluated :

• either using the "true" or "false" strings
• or using the default value if the expression to parse is null
• or using the Standard Thymeleaf Expression in all other cases

parseStringAttribute

public static String parseStringAttribute(org.thymeleaf.Arguments arguments,
                          org.thymeleaf.dom.Element element,

Parses the value of an attribute as a String.

Parameters:

arguments - Thymeleaf Arguments

element - The element in which an attribute is to be parsed.

attributeName - The attribute name for which the value is to be parsed.

Returns:

A string which is evaluated :

• either using a specific case (e.g. asc/desc)
• or using the default value if the expression to parse is null
• or using the Standard Thymeleaf Expression in all other cases

forceParsingStringAttribute

public static String forceParsingStringAttribute(org.thymeleaf.Arguments arguments,
                                 org.thymeleaf.dom.Element element,
                                 String attributeName)

parseAttribute

public static <T> T parseAttribute(org.thymeleaf.Arguments arguments,

                   String attributeName,
                   Class<T> clazz)

Parses the value of an attribute according to the provided clazz.

Parameters:
