Returns a deep, unattached copy of this child and its descendants detached from any parent or document.

Returns: a detached deep copy of this child and descendants

detach

public Content detach()

Detaches this child from its parent or does nothing if the child has no parent.

Returns: this child detached

This tests for equality of this Content object to the supplied object. Content items are considered equal only if they are referentially equal (i.e. the same object). User code may choose to compare objects based on their properties instead.

Parameters: ob Object to compare to.

Returns: boolean - whether the Content is equal to the supplied Object.

getDocument

public Document getDocument()

Return this child's owning document or null if the branch containing this child is currently not attached to a document.

getParentElement

public Element getParentElement()

A convenience method that returns any parent element for this element, or null if the element is unattached or is a root element. This was the original behavior of getParent() in JDOM Beta 9 which began returning Parent in Beta 10. This method provides a convenient upgrade path for JDOM Beta 10 and 1.0 users.

Returns: the containing Element or null if unattached or a root element

getValue

public abstract String getValue()

Returns the XPath 1.0 string value of this child.

Returns: xpath string value of this child.
