| Memory Analyzer has a built-in object query language |
| (OQL) that allows to query the heap dump with custom |
| SQL-like queries. Just think of classes as tables, |
| objects as rows, and fields as columns. The basic syntax |
| is this:</p> |
| |
| <pre class="pre codeblock"><code>SELECT * FROM [ INSTANCEOF ] <class_name> [ WHERE <filter-expression>] |
| </code></pre> |
