Method Detail

findLeafNodeAtOffset

public static org.eclipse.xtext.nodemodel.ILeafNode findLeafNodeAtOffset(org.eclipse.xtext.nodemodel.INode node,
                                                                         int leafNodeOffset)

Find the leaf node at the given offset. May return null if the given offset is not valid for the node (sub-)tree. A node matches the leafNodeOffset if it fulfills the following condition:

  node.totalOffset <= leafNodeOffset &&
  node.totalEndOffset > leafNodeOffset
 

This implementation is faster than original NodeModelUtils.findLeafNodeAtOffset(INode, int) for big node model

Parameters:

node - the container node. May not be null.

leafNodeOffset - the offset that is covered by the searched node

Returns:

the leaf node at the given offset or null if node was not found

findLeafNodeAtOffsetStartFromBack

public static org.eclipse.xtext.nodemodel.ILeafNode findLeafNodeAtOffsetStartFromBack(org.eclipse.xtext.nodemodel.INode node,
                                                                                      int leafNodeOffset)

Find the leaf node at the given offset, the search will be started from the last lead node child of node. May return null if the given offset is not valid for the node (sub-)tree. A node matches the leafNodeOffset if it fulfills the following condition:

  node.totalOffset <= leafNodeOffset &&
  node.totalEndOffset > leafNodeOffset
 

This implementation is faster than original NodeModelUtils.findLeafNodeAtOffset(INode, int) for big node model

Parameters:

node - the container node. May not be null.

leafNodeOffset - the offset that is covered by the searched node

Returns:

the leaf node at the given offset or null if node was not found
