Public Member Functions
int	init_time_range (valtype t0, valtype dt, valtype t1=-1)
	This data must accompany the file to know the correct range.
virtual int	set_internal_range (valtype r0, valtype r1, valtype dr)
	Setting arbitrary internal range is not allowed.
Public Member Functions inherited from emSourceWave
virtual int	GetFieldsShift () const
	Get the time shift between E and H fields in half time steps Default (analytic) wave has zero shift.
int	free_buffers ()
	Frees all buffer memory and the buffer array.
void	reset_buffers ()
	Frees buffer memory and prepares the buffers to resize (when new range is set)
virtual int	set_range (valtype tf0_=1, valtype tf1_=0, valtype dtf_=-1)
	sets t/f range and step for output: needed to optimize buffer usage when transformation is needed.

virtual int	set_tf (valtype tf)
	sets current time variable: t or f depending on current working signature

virtual void	Step (int field)
	To use from two-stage leap-frog timestepping.

emDump *	GetEmDumper ()
	This function insures that the returned dumper is of true emDumper type.

Protected Member Functions

Detailed Description

Reads field from binary file which contains field evolution in chosen points set.

In parallel versin, only zeroth processor reads the file.

Member Function Documentation

init_file()

int emFileWave::init_file ( )

protected

Initializes the previously recorded data; checks that the record size matches full set size.

Returns

<0 in case of an error.

init_time_range()

int emFileWave::init_time_range	(	valtype	t0,
		valtype	dt,
		valtype	t1 = -1
	)

This data must accompany the file to know the correct range.

If t1>=0 then some rest part of file is ignored.
