Member Function Documentation

void AllocStatData::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 in AllocAbstractStatThreadObject, AllocObjectMethod, AllocObjectTrace, AllocThreadObject, AllocThreadObjectMethod, and AllocThreadObjectTrace. Definition at line 37 of file allocStatData.cpp. Referenced by AllocThreadObjectTrace::addMemoryStat(), AllocThreadObjectMethod::addMemoryStat(), AllocThreadObject::addMemoryStat(), AllocObjectTrace::addMemoryStat(), AllocObjectMethod::addMemoryStat(), and AllocAbstractStatThreadObject::addMemoryStat().

Buffer & AllocStatData::dataToBin (  Buffer &    b )  [virtual]

Convert data to binary. This method converts statistic 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 DataBinaryFormat. Definition at line 56 of file allocStatData.cpp.

void AllocStatData::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 in AllocAbstractStatThreadObject, AllocObjectMethod, AllocObjectTrace, AllocThreadObject, AllocThreadObjectMethod, and AllocThreadObjectTrace. Definition at line 48 of file allocStatData.cpp. Referenced by AllocThreadObjectTrace::subMemoryStat(), AllocThreadObjectMethod::subMemoryStat(), AllocThreadObject::subMemoryStat(), AllocObjectTrace::subMemoryStat(), AllocObjectMethod::subMemoryStat(), and AllocAbstractStatThreadObject::subMemoryStat().
