Examples of IDOMPosition

org.eclipse.jst.pagedesigner.dom.IDOMPosition
An IDOMPosition represents a position in the DOM tree. There are multiple ways of identify a position in the tree, such as by saying a offset in parent, or before/after a particular node. NOTE: IDOMPosition and its child class should be implemented as literal. that is, they should not be changed after it is constructed. @author mengbo
