Constructor Detail

InsertInto

public InsertInto(int p,
          Data d,
          InputInfo i,
          NodeCache nc,
          boolean l)

Constructor.

Parameters:

p - pre

d - data

i - input info

nc - node copy

l - insert into as last

Method Detail

apply

public void apply()

Description copied from class: UpdatePrimitive

Applies this update primitive to the corresponding database.

adjacentTexts

public boolean adjacentTexts(int c)

Description copied from class: StructuralUpdate

Checks whether adjacent text nodes have been introduced as a result of this update primitive. Text node adjacency can only be taken care of if no more updates are to be expected for the left sibling of this target node. The total number of deleted/inserted nodes on the preceding axis of this target node is given recalculate the actual pre value of this target.

Specified by:

adjacentTexts in class StructuralUpdate

Parameters:

c - pre value shifts introduced by updates on the preceding sibling axis of this target node

Returns:

adjacent text nodes have been found and merged

merge

public void merge(UpdatePrimitive p)

Description copied from class: UpdatePrimitive

Merges two update primitives, as they have the same target node.

Specified by:

merge in class UpdatePrimitive

Parameters:

p - primitive to merge with
