Used to load the recognition tree and perform lookups of all properties, or
individual properties. Typical usage is as follows: <br />
<code>
<br /> HashMap tree = Api.getTreeFromFile("sample/DeviceAtlas.json");
<br /> HashMap prps = Api.getProperties(tree, "Nokia6680...");
<br /> Object prop = Api.getProperty(tree, "Nokia6680...", "displayWidth");
</code>
<br />
<br />
Note that you should normally use the user-agent that was received in the
device's HTTP request. In a JSP environment, you would do this as follows:
<br />
<code>
<br />String ua = request.getHeader("User-Agent");
<br />int displayWidth = Api.getPropertyAsInteger(tree, ua, "displayWidth");
</code>
<br />
<br />
(Also note the use of the strongly typed property accessor) <br />
In some contexts, the user-agent you want to recognise may have been provided
in a different header. Opera's mobile browser, for example, makes requests
via an HTTP proxy, which rewrites the headers. in that case, the original
device's user-agent is in the "X-OperaMini-Phone-UA" header, and the
following code could be used: <br />
<code>
<br />String ua;
<br />String operaHeader = "X-OperaMini-Phone-UA";
<br />if (request.getHeader(operaHeader) != null) {
<br /> ua = request.getHeader(operaHeader);
<br />} else {
<br /> ua = request.getHeader("User-Agent");
<br />}
<br />int displayWidth = Api.getPropertyAsInteger(tree, ua, "displayWidth");
</code>
