| * VM Testbase keywords: [quick, jpda, jvmti, noras] |
| * VM Testbase readme: |
| * This test exercises JVMTI function IterateOverHeap(). |
| * Test checks that for slected heap-filter all expected objects will be reached |
| * and reported by appropriate callback. |
| * Test consist of two mostly idential classes. |
| * Agent tags instance and class of first one of them as well as it's non-primitive fields. |
| * Depending on heap-filter selected by agent's 'filter' option for each field in instances |
| * of those two classes flag that indicates whether or not field should be reported by |
| * any callback is calculated. |
| * Classes of non-primitive fields are not tagged. |
| * Following table illustrates which fields depending on their type and selected heap |
| * filter are expected to be reported: |
| * object\Filter TAGGED UNTAGGED CLASS_TAGGED CLASS_UNTAGGED |
| * Tagged class |
| * primitive static field - + + - |
| * primitive instance field - + - + |
| * primitive array field - + + - |
| * String field - + + - |
| * Untagged class |
| * primitive static field + - + - |
| * primitive instance field + - + - |
| * primitive array field + - + - |
| * String field + - + - |
| * HeapFilter agent support option filter=<heap-filter>, where <heap-filter> is one of the following: |
| * JVMTI_HEAP_FILTER_TAGGED |
| * JVMTI_HEAP_FILTER_UNTAGGED |
| * JVMTI_HEAP_FILTER_CLASS_TAGGED |
| * JVMTI_HEAP_FILTER_CLASS_UNTAGGED |
| * Test filter-tagged uses JVMTI_HEAP_FILTER_TAGGED. |
| * Test filter-untagged uses JVMTI_HEAP_FILTER_UNTAGGED. |
| * Test filter-class-tagged uses JVMTI_HEAP_FILTER_CLASS_TAGGED. |
| * Test filter-class-untagged uses JVMTI_HEAP_FILTER_CLASS_UNTAGGED. |
