| DomRangeImpl | | class DomRangeImpl implements DomProvider.DomRange(Code) | | XXX Moved from designer/../Range.
Represents a range: two positions, where one position
is considered the "dot" (current location). E.g. if you
swipe select out a range, the "start" point of the selection
is the mark, and the "end" point is the mark.
Implementation notes: I first used DOM Range directly,
but that doesn't work well for example within rendered jsf
fragments, since the Range can only be attached to the Document
itself; it also had no concept of dot and mark, so I was having
to track this state separately along with the range, and there's
some cleanup logic to be done, so all this is now managed by
this class.

| Method Summary | |
| public static DomRange | create(DomDocumentImpl domDocumentImpl, Node dotNode, int dotOffset, Node markNode, int markOffset)
| | public boolean | deleteRangeContents()
Delete the contents of the selection. | | public void | detach()
| | public DomPosition | getDot()
Fetches the current position of the caret. | | public DomPosition | getFirstPosition()
Return the first endpoint of the range in the document. | | public DomPosition | getLastPosition()
Return the second/last endpoint of the range in the document. | | public DomPosition | getMark()
Fetches the current position of the caret. | | public boolean | isDot(DomPosition dot)
| | public boolean | isEmpty()
Return true iff the range is empty, e.g. | | public boolean | isReadOnlyRegion()
| | public void | setDot(Node dotNode, int dotOffset, Bias bias)
| | public void | setMark(Node markNode, int markOffset, Bias bias)
| | public void | setRange(Node start, int startOffset, Node end, int endOffset)
| | public String | toString()
|
| deleteRangeContents | | public boolean deleteRangeContents()(Code) | | Delete the contents of the selection. Beep if the range is read-only.
true iff the deletion succeeded (an empty selection can alwaysbe successfully deleted) |
| detach | | public void detach()(Code) | | Free up resources associated with this range
|
| getDot | | public DomPosition getDot()(Code) | | Fetches the current position of the caret.
the position >= 0 |
| getFirstPosition | | public DomPosition getFirstPosition()(Code) | | Return the first endpoint of the range in the document.
|
| getLastPosition | | public DomPosition getLastPosition()(Code) | | Return the second/last endpoint of the range in the document.
|
| getMark | | public DomPosition getMark()(Code) | | Fetches the current position of the caret.
the position >= 0 |
| isDot | | public boolean isDot(DomPosition dot)(Code) | | Return true iff the given position coincides with the dot position
|
| isEmpty | | public boolean isEmpty()(Code) | | Return true iff the range is empty, e.g. the dot and mark are the same
|
| isReadOnlyRegion | | public boolean isReadOnlyRegion()(Code) | | Return true iff the range is in a read-only region
|
| setDot | | public void setDot(Node dotNode, int dotOffset, Bias bias)(Code) | | |
| setMark | | public void setMark(Node markNode, int markOffset, Bias bias)(Code) | | |
| setRange | | public void setRange(Node start, int startOffset, Node end, int endOffset)(Code) | | |
