Field Details

GLOBAL

public static final ILcdXMLDocumentContext.Scope GLOBAL

The GLOBAL scope is to be used for variables that need to be accessible within the whole document. Setting a new value for the variable will permanently override. the old value. The variable will only be invalidated at the end of the decoding process, or if a null value is set for it.

DESCENDANTS

public static final ILcdXMLDocumentContext.Scope DESCENDANTS

The DESCENDANTS scope is to be used for variables that need only be accessible in the current XML element and all of its children. Setting a new value for the variable in one of the descendants, will override the old value for that descendant and all of its children. The variable will be invalidated when the element, in which the variable was set, is ended, or if a null value is set in that element. This scope works as a stack, where the actual value of the variable corresponds the value currently on top of the stack.

LOCAL

public static final ILcdXMLDocumentContext.Scope LOCAL

The LOCAL scope is to be used for variables that need only be accessible in the current XML element. Setting a new value for the variable in that element will permanently override the old value. The variable will be invalidated when the element, in which the variable was set, is ended, or if a null value is set in that element.
