Detailed Description

Thread.

This class consists of data gained by receiving the JVMPI_EVENT_THREAD_START event. When the thread stops (JVMPI_EVENT_THREAD_END event received), data in this structure is no longer valid, so 'active' field will equal zero.

Member Function Documentation

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

Class identification. Returns: unique class type identifier Reimplemented from IdObject. Definition at line 232 of file thread.h.

JNIEnv* const& Thread::getKey (  JNIEnv *&    key )  [inline]

Retrieves object's key. Parameters: key  where to store the key Returns: key See also: Hash Definition at line 174 of file thread.h. Referenced by MonThreadMethod::getKey(), CpuThreadMethod::getKey(), AllocThreadObject::getKey(), and AllocThreadMethod::getKey().

int Thread::hashKey (  JNIEnv *const &    key )  [inline, static]

Hash function. Parameters: key  reference to a key Returns: hash value Definition at line 193 of file thread.h. Referenced by MonThreadTrace::hashKey(), MonThreadMethod::hashKey(), CpuThreadTrace::hashKey(), CpuThreadMethod::hashKey(), AllocThreadTrace::hashKey(), AllocThreadObjectTrace::hashKey(), AllocThreadObjectMethod::hashKey(), AllocThreadObject::hashKey(), and AllocThreadMethod::hashKey().

Buffer & Thread::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 47 of file thread.cpp.

virtual int Thread::isActive (    )  [inline, 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 240 of file thread.h. Referenced by MonThreadMethod::isActive(), CpuThreadMethod::isActive(), AllocThreadObject::isActive(), and AllocThreadMethod::isActive().

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

Indication that object has changed its data. Returns: 0 (no change); 1 (data changed) Reimplemented from IdObject. Definition at line 247 of file thread.h.

int Thread::operator== (  JNIEnv *const &    key )  [inline]

Compares object with given key. Parameters: key  key Returns: 1 (true); 0 (false) See also: Hash Definition at line 185 of file thread.h.
