Detailed Description

Crossroad of traces and objects-methods.

This class defines a relation between traces (specify where an object was allocated) and objects-methods (another relation described in AllocObjectMethod class description). It would be nice to have information where an object of given type was allocated - in which method (and to have a stack of called methods for each object where the last one in this stack made an allocation of the object).

Remember: a method allocates an object; this method can be called from various methods; these call sequences of methods divide objects of the same type to groups, two objects of the same type are equivalent if they're in the same group, so they're allocated using the same call sequence. Trace is one of these call sequences. In this way we gained the highest granularity of data.

Member Function Documentation

void AllocObjectTrace::addMemoryStat (  jint    size )  [virtual]

Addition of the object's size to statistics. This method adds size of object to the statistic data. It changes number of live/total instances, too. Parameters: size  size of object (in number of bytes) See also: subMemoryStat() Reimplemented from AllocAbstractStatThreadObject. Definition at line 45 of file allocObjectTrace.cpp. Referenced by AllocThreadObjectTrace::addMemoryStat().

void AllocObjectTrace::clearFlag (    )  [virtual]

Clearing of flag. This method sets the modification flag to zero. Reimplemented from AllocAbstractStatThreadObject. Definition at line 67 of file allocObjectTrace.cpp. Referenced by AllocThreadObjectTrace::clearFlag().

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

Class identification. Returns: unique class type identifier Reimplemented from IdObject. Definition at line 176 of file allocObjectTrace.h.

const AllocObjectTraceKey & AllocObjectTrace::getKey (  AllocObjectTraceKey &    key )

Retrieves object's key. Parameters: key  where to store the key Returns: key See also: Hash Definition at line 79 of file allocObjectTrace.cpp. Referenced by AllocThreadObjectTrace::getKey().

int AllocObjectTrace::hashKey (  const AllocObjectTraceKey &    key )  [static]

Hash function. Parameters: key  reference to a key Returns: hash value Definition at line 91 of file allocObjectTrace.cpp.

int AllocObjectTrace::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 96 of file allocObjectTrace.cpp. Referenced by AllocThreadObjectTrace::isActive().

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

Indication that object has changed its data. Returns: 0 (no change); 1 (data changed) Reimplemented from IdObject. Definition at line 191 of file allocObjectTrace.h.

int AllocObjectTrace::operator== (  const AllocObjectTraceKey &    key )

Compares object with given key. Parameters: key  key Returns: 1 (true); 0 (false) See also: Hash Definition at line 86 of file allocObjectTrace.cpp.

void AllocObjectTrace::subMemoryStat (  jint    size )  [virtual]

Subtraction of the object's size from statistics. This method subtracts size of object from the statistic data. It changes number of live instances, too. Parameters: size  size of object (in number of bytes) See also: addMemoryStat() Reimplemented from AllocAbstractStatThreadObject. Definition at line 56 of file allocObjectTrace.cpp. Referenced by AllocThreadObjectTrace::subMemoryStat().
