-Object Query Language (OQL)
-</title>
-</head>
-<body>
-<h1>Object Query Language (OQL)</h1>
-
-<p>
-OQL is SQL-like query language to query Java heap. OQL allows to filter/select information
-wanted from Java heap. While pre-defined queries such as "show all instances of class X"
-are already supported by HAT, OQL adds more flexibility. OQL is based on JavaScript expression
-language.
-</p>
-
-<p>
-OQL query is of the form
-
-<pre>
-<code>
- <span class="key">select</span> <JavaScript expression to select>
- [ <span class="key">from</span> [<span class="key">instanceof</span>] <class name> <identifier>
- [ <span class="key">where</span> <JavaScript boolean expression to filter> ] ]
-</code>
-</pre>
-where class name is fully qualified Java class name (example: java.net.URL) or array class name.
-[C is char array name, [Ljava.io.File; is name of java.io.File[] and so on.
-Note that fully qualified class name does not always uniquely identify a
-Java class at runtime. There may be more than one Java class with the same
-name but loaded by different loaders. So, class name is permitted to be
-id string of the class object.
-
-If <span class="key">instanceof</span> keyword is used, subtype objects are selected. If this
-keyword is not specified, only the instances of exact class specified are selected. Both
-<span class="key">from</span> and <span class="key">where</span> clauses are optional.
-</p>
-
-
-<p>
-In <span class="key">select</span> and (optional) <span class="key">where</span> clauses, the expression
-used in JavaScript expression. Java heap objects are wrapped as convenient script objects so that
-fields may be accessed in natural syntax. For example, Java fields can be accessed with obj.field_name
-syntax and array elements can be accessed with array[index] syntax. Each Java object selected is
-bound to a JavaScript variable of the identifier name specified in <span class="key">from</span> clause.
-</p>
-
-<h2>OQL Examples</h2>
-
-<ul>
-<li>select all Strings of length 100 or more
-<pre>
-<code>
- select s from java.lang.String s where s.value.length >= 100
-</code>
-</pre>
-<li>select all int arrays of length 256 or more
-<pre>
-<code>
- select a from [I a where a.length >= 256
-</code>
-</pre>
-<li>show content of Strings that match a regular expression
-<pre>
-<code>
- select s.value.toString() from java.lang.String s
- where /java/.test(s.value.toString())
-</code>
-</pre>
-<li>show path value of all File objects
-<pre>
-<code</b>
- select file.path.value.toString() from java.io.File file
-</code>
-</pre>
-<li>show names of all ClassLoader classes
-<pre>

-<h3>More complex examples</h3>
-
-<h4>Print histogram of each class loader and number of classes loaded by it</h4>
-
-<pre>
-<code>
- select <a href="#map">map</a>(<a href="#sort">sort</a>(map(heap.objects('java.lang.ClassLoader'),
- '{ loader: it, count: it.classes.elementCount }'), 'lhs.count < rhs.count'),
- 'toHtml(it) + "<br>"')
-</code>
-</pre>
-<p>
-The above query uses the fact that, <b>java.lang.ClassLoader</b> has a private
-field called <b>classes</b> of type <b>java.util.Vector</b> and Vector has a
-private field named <b>elementCount</b> that is number of elements in the
-vector. We select multiple values (loader, count) using JavaScript object
-literal and map function. We sort the result by count (i.e., number of classes
-loaded) using sort function with comparison expression.
-</p>
-
-<h4>Show parent-child chain for each class loader instance</h4>
-
-<pre>
-<code>
- select <a href="#map">map</a>(heap.objects('java.lang.ClassLoader'),
- function (it) {
- var res = '';
- while (it != null) {
- res += toHtml(it) + "->";
- it = it.parent;
- }
- res += "null";
- return res + "<br>";
- })
-</code>
-</pre>
-<p>
-Note that we use <b>parent</b> field of <b>java.lang.ClassLoader</b> class
-and walk until parent is null using the callback function to map call.
-</p>
-
-<h4>Printing value of all System properties</h4>
-
-<pre>
-<code>
- select <a href="#map">map</a>(<a href="#filter">filter(<a href="#findClass">heap.findClass</a>('java.lang.System').statics.props.table, 'it != null'),
- function (it) {
- var res = "";
- while (it != null) {
- res += it.key.value.toString() + '=' +
- it.value.value.toString() + '<br>';
- it = it.next;
- }
- return res;
- });
-</code>
-</pre>
-<p>
-The above query uses the following facts:
-<ul>
-<li>java.lang.System has static field by name 'props' of type java.util.Properties.
-<li>java.util.Properties has field by 'table' of type java.util.Hashtable$Entry
-(this field is inherited from java.util.Hashtable). This is the hashtable
-buckets array.
-<li>java.util.Hashtable$Entry has 'key', 'value' and 'next' fields. Each
-entry points the next entry (or null) in the same hashtable bucket.
-<li>java.lang.String class has 'value' field of type char[].
-</ul>
-<p>
-<b>Note that this query (and many other queries) may not be stable - because
-private fields of Java platform classes may be modified/removed without any
-notification! (implementation detail)</b>. But, using such queries on user
-classes may be safe - given that user has the control over the classes.
