a template compatibility string (should not contain whitespace or punctuation)

Specified by:

getTemplateContext in interface I_CmsTemplateContextProvider

Parameters:

cms - the CMS context

request - the current request

resource - the resource being rendered

Returns:

the current template context

Checks if the template context should be hidden in the GUI.

Specified by:

isHiddenContext in interface I_CmsTemplateContextProvider

Parameters:

key - the key of a template context

Returns:

true if the template context should be hidden in the GUI

readCommonProperty

public java.lang.String readCommonProperty(CmsObject cms,

                                           java.lang.String fallbackValue)

Description copied from interface: I_CmsTemplateContextProvider

Gets the value which should be used instead of a property which was read from the template resource.

This is needed because before template context providers, it was common to store template-specific configuration in a property on the template JSP. Since template context providers make the result ambiguous, this method is intended as a replacement.

Specified by:

readCommonProperty in interface I_CmsTemplateContextProvider

Parameters:

cms - the CMS context to use

propertyName - the name of the property

fallbackValue - the value to return if no value is found or an error occurs
