Types

type Index

type Index struct {
	// contains filtered or unexported fields
}

Index is indexed HProf data.

func OpenOrCreateIndex

func OpenOrCreateIndex(heapFilePath, indexFilePath string) (*Index, error)

OpenOrCreateIndex opens or creates a DB based on the HProf file.

func (*Index) Class

func (idx *Index) Class(classObjectID uint64) (*hprofdata.HProfClassDump, error)

Class returns a HProfClassDump based on a class object ID.

func (*Index) ForEachRootJNIGlobal

func (idx *Index) ForEachRootJNIGlobal(fn func(*hprofdata.HProfRootJNIGlobal) error) error

ForEachRootJNIGlobal iterates through all HProfRootJNIGlobal objects.

func (*Index) ForEachRootJNILocal

func (idx *Index) ForEachRootJNILocal(fn func(*hprofdata.HProfRootJNILocal) error) error

ForEachRootJNILocal iterates through all HProfRootJNILocal objects.

func (*Index) ForEachRootJavaFrame

func (idx *Index) ForEachRootJavaFrame(fn func(*hprofdata.HProfRootJavaFrame) error) error

ForEachRootJavaFrame iterates through all HProfRootJavaFrame objects.

func (*Index) ForEachRootStickyClass

func (idx *Index) ForEachRootStickyClass(fn func(*hprofdata.HProfRootStickyClass) error) error

ForEachRootThreadObj iterates through all HProfRootThreadObj objects.

func (*Index) Frame

func (idx *Index) Frame(stackFrameID uint64) (*hprofdata.HProfRecordFrame, error)

Frame returns a HProfRecordFrame based on a stack frame ID.

func (*Index) Instance

func (idx *Index) Instance(objectID uint64) (*hprofdata.HProfInstanceDump, error)

Instance returns a HProfInstanceDump based on an object ID.

func (*Index) LoadedClass
