Constructor & Destructor Documentation

HldInput()

hadaq::HldInput::HldInput

(

const dabc::Url &

ulr

)

Definition at line 26 of file HldInput.cxx.

~HldInput()

hadaq::HldInput::~HldInput ( )

virtual

Member Function Documentation

CloseFile()

bool hadaq::HldInput::CloseFile ( )

protected

Definition at line 65 of file HldInput.cxx.

OpenNextFile()

bool hadaq::HldInput::OpenNextFile ( )

protected

Definition at line 48 of file HldInput.cxx.

Read_Init()

bool hadaq::HldInput::Read_Init ( const dabc::WorkerRef &  wrk, const dabc::Command &  cmd  )

virtual

Initialize data input, using port and command.

This is generic virtual method to initialize input, using configurations from Port and (or) from the Command

Parameters

[in]	wrk	reference on input port
[in]	cmd	reference on command object

Returns

false when method fails

Reimplemented from dabc::FileInput.

Definition at line 41 of file HldInput.cxx.

Read_Size()

unsigned hadaq::HldInput::Read_Size ( )

virtual

Defines required buffer size for next operation.

Returns

• 0..di_ValidSize - size of buffer for next read operation (di_ValidSize = 0xFFFFFFF0)
• di_EndOfStream - this is end of stream, normal close of the input
• di_DfltBufSize - any non-zero buffer can be provided
• di_Repeat - nothing to read now, try again as soon as possible
• di_RepeatTimeOut - nothing to read now, try again after timeout
• di_CallBack - input will activate transport via callback
• di_Error - error, close input

Reimplemented from dabc::DataInput.

Definition at line 72 of file HldInput.cxx.

Read_Complete()

unsigned hadaq::HldInput::Read_Complete ( dabc::Buffer &  buf )

virtual

Complete reading of the buffer from source,.

Returns

• di_Ok - buffer filled and ready
• di_EndOfStream - this is end of stream, normal close of the input
• di_SkipBuffer - skip buffer
• di_Error - error, skip buffer and close input
• di_Repeat - not ready, call again as soon as possible
• di_RepeatTimeOut - not ready, call again after timeout

Reimplemented from dabc::DataInput.

Definition at line 82 of file HldInput.cxx.
