Apparatus and Method for Displaying Hierarchical Data
A computer readable storage medium includes executable instructions to receive a request for tree node information and apply one or more tree node parameter limits to the request. The tree node parameter limits include a tree node level limit and a sibling node count limit. The computer readable storage medium further includes executable instructions to receive tree node objects corresponding to the tree node parameter limits, add the tree node objects to a dynamically extended tree node data structure and display a first portion of the tree node objects.
1 . A computer readable storage medium comprising executable instructions to:
receive a request for tree node information;
apply one or more tree node parameter limits to the request, wherein the tree node parameter limits comprise at least one of a tree node level limit and a sibling node count limit;
receive tree node objects corresponding to the tree node parameter limits;
add the tree node objects to a dynamically extended tree node data structure; and
display a first portion of the tree node objects.
2 . The computer readable medium of claim 1 , wherein the executable instructions to display the first portion of the tree node objects further comprises executable instructions to render the first portion of the tree node objects in a Document Object Model (DOM) structure corresponding to the tree node data structure.
3 . The computer readable medium of claim 1 , further comprising executable instructions to display a second portion of the tree node objects.
4 . The computer readable medium of claim 3 , wherein the executable instructions to display the second portion of the tree node objects further comprises executable instructions to render the second portion of the tree node objects in a Document Object Model (DOM) structure corresponding to the tree node data structure.
5 . The computer readable medium of claim 1 , further comprising executable instructions to receive additional tree node objects corresponding to one or more additional tree node parameter limits.
6 . The computer readable medium of claim 5 , further comprising executable instructions to add the additional tree node objects to the dynamically extended tree node structure based on identifying one or more hierarchical relationships between the tree node objects and the additional tree node objects.
7 . The computer readable medium of 1 , wherein the executable instructions to add the tree node objects comprise executable instructions to dynamically extend an object definition corresponding to the tree node objects.
8 . The computer readable medium of 1 , wherein the tree node parameter limits are specified using a plurality of Extensible Markup Language (XML) Hyper Text Transfer Protocol (HTTP) requests.
9 . The computer readable medium of 1 , further comprising executable instructions to receive the tree node objects in a Java Script Object Notation (JSON) format.
10 . A computer readable storage medium comprising executable instructions to:
receive one or more tree node parameter limits, wherein the tree node parameter limits comprise at least one of a tree node level limit and a sibling node count limit;
retrieve tree node objects corresponding to the tree node parameter limits; and
deliver the tree node objects.
11 . A computer readable storage medium, comprising executable instructions to:
request a set of node objects in a hierarchical data structure, wherein each node object in the set includes a definition;
receive the set of node objects, wherein each node object represents a connected part of the hierarchical data structure; and
extend the definition of each node object in the set.
12 . The computer readable storage medium of claim 11 , wherein the executable instructions to extend the definition of each node object include executable instructions to update a node object within an annotation comprising at least one of a child annotation and a sibling annotation.
13 . The computer readable storage medium of claim 12 wherein the sibling annotation is selected from a first annotation corresponding to a representative object having more siblings than received, and a second annotation corresponding to a representative object having children.
14 . The computer readable storage medium of claim 11 , further comprising executable instructions to render the set of node objects forming the connected part of the hierarchical data structure.
15 . The computer readable storage medium of claim 14 , wherein the executable instructions to render include executable instructions to render at least one of a tree, a directed graph, an array and a table.
16 . The computer readable storage medium of claim 11 , further comprising executable instructions to add to a specified point in the hierarchical data structure a second set of node objects, wherein the specified point is based on at least one of a hierarchical relationship between node objects, a previous sibling reference, a next sibling reference, a parent reference and a visible node count.
