Member Function Documentation

◆ Clear()

void TTreeCacheUnzip::UnzipState::Clear ( Int_t size )

Clear all baskets' state arrays.

Definition at line 51 of file TTreeCacheUnzip.cxx.

◆ IsFinished()

Bool_t TTreeCacheUnzip::UnzipState::IsFinished ( Int_t index ) const

Definition at line 75 of file TTreeCacheUnzip.cxx.

◆ IsProgress()

Bool_t TTreeCacheUnzip::UnzipState::IsProgress ( Int_t index ) const

Definition at line 69 of file TTreeCacheUnzip.cxx.

◆ IsUntouched()

Bool_t TTreeCacheUnzip::UnzipState::IsUntouched ( Int_t index ) const

Definition at line 63 of file TTreeCacheUnzip.cxx.

◆ IsUnzipped()

Bool_t TTreeCacheUnzip::UnzipState::IsUnzipped ( Int_t index ) const

Check if the basket is unzipped already.

We must make sure the length in fUnzipLen is larger than 0.

Definition at line 83 of file TTreeCacheUnzip.cxx.

◆ Reset()

void TTreeCacheUnzip::UnzipState::Reset	(	Int_t	oldSize,
		Int_t	newSize
	)

Reset all baskets' state arrays.

This function is only called by main thread and parallel processing from upper layers should be disabled such as IMT in TTree::GetEntry(). Other threads should not call this function since it is not thread-safe.

Definition at line 93 of file TTreeCacheUnzip.cxx.

◆ SetFinished()

void TTreeCacheUnzip::UnzipState::SetFinished ( Int_t index )

Set cache as finished.

There are three scenarios that a basket is set as finished:

The basket has already been unzipped.
The thread is aborted from unzipping process.
To avoid other tasks/threads work on this basket, main thread marks the basket as finished and designates itself to unzip this basket.

Definition at line 124 of file TTreeCacheUnzip.cxx.

◆ SetMissed()

void TTreeCacheUnzip::UnzipState::SetMissed ( Int_t index )

Definition at line 132 of file TTreeCacheUnzip.cxx.

◆ SetProgress()

void TTreeCacheUnzip::UnzipState::SetProgress ( Int_t index )

◆ SetUntouched()

void TTreeCacheUnzip::UnzipState::SetUntouched ( Int_t index )

◆ SetUnzipped()

void TTreeCacheUnzip::UnzipState::SetUnzipped	(	Int_t	index,
		char *	buf,
		Int_t	len
	)

Definition at line 139 of file TTreeCacheUnzip.cxx.

◆ TryUnzipping()

Bool_t TTreeCacheUnzip::UnzipState::TryUnzipping ( Int_t index )

Start unzipping the basket if it is untouched yet.
