The objective of the DeleteNode class is to delete an existing node from a tree (identified by the folders table). To delete an existing node, you need to supply the ID of the node being deleted. Also, you need to indicate whether to promote the subtree of the deleted node; you pass this argument as a boolean (true/false). So, the DeleteNode class s main() method will accept two arguments: the ID of the node to be deleted and a boolean (true/false) to indicate the promotion of the subtree of the deleted node. If a node is a leaf node, it is easy to delete it, because it has no impact on other nodes. But if a node to be deleted is an inner node (a nonleaf node, which has at least one child), then the deletion process is complex. When a node is deleted from the tree, you have to preserve the integrity of the tree if the node has any subnodes. You have two approaches:

<columnMetaData column="3" columnDisplaySize="65535" columnLabel="photo" columnName="photo" columnType="-4" columnTypeName="BLOB" columnClassName="java.lang.Object" tableName="mypictures" precision="0" scale="0" isAutoIncrement="false" isCurrency="false" isWritable="false" isDefinitelyWritable="false" isNullable="1" isReadOnly="false" isCaseSensitive="true" isSearchable="true" isSigned="false" catalog="null" schema="" /> </resultSetMetaData> ------------------------------------

Sometimes while entering numerical values, we come across negative values. In the preceding jQuery code, no symbol is allowed; that is, we cannot use a hyphen or minus sign. Hence we cannot enter a negative value in the text field with the preceding code. Let s modify our jQuery code to accept negative values also: $(document).ready(function() { $('.error').hide(); $('.submit').click(function(event){ var data=$('.infobox').val(); var len=data.length; var c; for(var i=0;i<len;i++) { c=data.charAt(i).charCodeAt(0); if(c==45 && i==0) { continue; } if(c <48 || c >57) { $('.error').show(); event.preventDefault(); break; }

The first approach is to promote one of the deleted node s children (a subnode) to take over the position of the deleted node. The remaining subnodes of the deleted node become subnodes to the promoted node. To understand this, take a look at the following figures: assume that the original tree is Figure 11-2, and you want to delete node B. Using the promotion approach, the resultant tree will become Figure 11-3. The second approach is to promote the entire subtree (all the children) of the deleted node so that all the subnodes of the deleted node become the subnodes of the deleted node s parent node. Assume that the original tree is Tree-1, and you want to delete node B. Using the promotion of the entire subtree approach, the resultant tree will become Figure 11-4.
