Detailed Description

Type of Java object.

This class consists of data about type of object. Java objects can be differentiated by the couple (class, isArray), where 'class' means class of the object and 'isArray' contains a value if the object is a normal object or an array of objects of the given 'class'. Data is aquired by receiving a JVMPI_EVENT_OBJECT_ALLOC event.

Member Function Documentation

virtual eClassIdent AllocObject::getClassIdent (    )  [inline, virtual]

Class identification. Returns: unique class type identifier Reimplemented from IdObject. Definition at line 169 of file allocObject.h.

const AllocObjectKey & AllocObject::getKey (  AllocObjectKey &    key )

Retrieves object's key. Parameters: key  where to store the key Returns: key See also: Hash Definition at line 81 of file allocObject.cpp. Referenced by AllocThreadObject::getKey(), and AllocObjectMethod::getKey().

int AllocObject::hashKey (  const AllocObjectKey &    key )  [static]

Hash function. Parameters: key  reference to a key Returns: hash value Definition at line 95 of file allocObject.cpp. Referenced by AllocObjectTrace::hashKey(), and AllocObjectMethod::hashKey().

Buffer & AllocObject::infoToBin (  Buffer &    b )  [virtual]

Convert info to binary. This method converts information data to binary format in which it is sent thru communication interface to client. Parameters: b  buffer where to append data Returns: reference to same Buffer object as argument 'b' Reimplemented from InfoBinaryFormat. Definition at line 43 of file allocObject.cpp.

int AllocObject::isActive (    )  [virtual]

State of object. Once an object is unactive, it remains unactive forever. Returns: 0 (not active); 1 (active) Reimplemented from IdObject. Definition at line 100 of file allocObject.cpp. Referenced by AllocThreadObject::isActive(), and AllocObjectMethod::isActive().

virtual int AllocObject::isChanged (    )  [inline, virtual]

Indication that object has changed its data. Returns: 0 (no change); 1 (data changed) Reimplemented from IdObject. Definition at line 184 of file allocObject.h.

int AllocObject::operator== (  const AllocObjectKey &    key )

Compares object with given key. Parameters: key  key Returns: 1 (true); 0 (false) See also: Hash Definition at line 88 of file allocObject.cpp.

Member Data Documentation

jint AllocObject::isArray

Type of object (eg. JVMPI_NORMAL_OBJECT, JVMPI_CLASS, JVMPI_BOOLEAN etc.). These values say if the object is normal object or an array of objects (of given class) or an array of primitive type (boolean, short etc.). See also: JVMPI documentation Definition at line 81 of file allocObject.h. Referenced by Prof::getAllocObject().
