SFH Sweep formula related helper code

Functions

variable SFH_StringChecker_Prototype(string str)
variable SFH_NumericChecker_Prototype(variable var)
variable SFH_GetArgumentAsNumeric(variable jsonId, string jsonPath, string graph, string opShort, variable argNum, variable defValue = defaultValue, WaveOrNull allowedValues = defaultValue, SFH_NumericChecker_Prototype checkFunc = defaultValue, variable checkDefault = defaultValue)

Convenience helper function to get a numeric SweepFormula operation argument.

Given the operation fetchBeer(variable numBottles, [variable size]) one can fetch both parameters via:

opShort    = "fetchBeer"
numBottles = SFH_GetArgumentAsNumeric(jsonId, jsonPath, graph, opShort, 0)
size       = SFH_GetArgumentAsNumeric(jsonId, jsonPath, graph, opShort, 1, defValue = 0.5, allowedValues = {0.33, 0.5, 1.0})

Here numBottles is argument number 0 and mandatory as defValue is not present.

The second argument size is optional with 0.5 as default and also defines a list of valid values.

string SFH_GetArgumentAsText(variable jsonId, string jsonPath, string graph, string opShort, variable argNum, string defValue = defaultValue, WaveTextOrNull allowedValues = defaultValue, SFH_StringChecker_Prototype checkFunc = defaultValue, variable checkDefault = defaultValue)

Convenience helper function to get a textual SweepFormula operation argument.

Given the operation getTrainTable(string date, [string type]) one can fetch both parameters via:

opShort = "getTrainTable"
date    = SFH_GetArgumentAsText(jsonId, jsonPath, graph, opShort, 0)
type    = SFH_GetArgumentAsText(jsonId, jsonPath, graph, opShort, 1, defValue = "steam train", allowedValues = {"steam train", "light rail"})

Here date is argument number 0 and mandatory as defValue is not present.

The second argument type is optional with steam train as default and a list of allowed values.

The text argument can be abbreviated as long as it is unique, the unabbreviated result is returned in all cases.

wave SFH_GetArgumentAsWave(variable jsonId, string jsonPath, string graph, string opShort, variable argNum, string defOp = defaultValue, WaveOrNull defWave = defaultValue, variable singleResult = defaultValue, variable expectedWaveType = defaultValue)

Convenience helper function to get a wave SweepFormula operation argument.

Given the operation countBirds(array birds, [birdTypes()]) one can fetch both parameters via:

opShort      = "countBirds"
WAVE/D birds = SFH_GetArgumentAsWave(jsonId, jsonPath, graph, opShort, 0, singleResult = 1)
WAVE/T types = SFH_GetArgumentAsWave(jsonId, jsonPath, graph, opShort, 1, defOp = "birdTypes()", singleResult = 1, expectedWaveType = IGOR_TYPE_TEXT_WAVE)

Here birds is argument number 0 and mandatory as defOp is not present. Passing singleResult == 1 already unpacks the outer wave reference wave container. It should always be passed if you only expect one wave to be returned.

The second argument birdTypes is optional, if not present the operation birdTypes() is called and its result returned. Alternatively defWave can be supplied which is then returned if the argument is not present.

variable SFH_ASSERT(variable condition, string message, variable jsonId = defaultValue)

Assertion for sweep formula.

This assertion does not indicate a general programmer error but a sweep formula user error.

All programmer error checks must still use ASSERT().

UTF_NOINSTRUMENTATION

wave SFH_GetEmptyRange()
variable SFH_IsEmptyRange(wave range)
wave SFH_GetFullRange()
variable SFH_IsFullRange(wave range)
wave SFH_AsDataSet(wave data)
static variable SFH_ExtendIncompleteRanges(wave ranges)

Formula “cursors(A,B)” can return NaNs if no cursor(s) are set.

wave SFH_EvaluateRange(variable jsonId, string jsonPath, string graph, string opShort, variable argNum)

Evaluate range parameter.

Range is read as dataset(s), it can be per dataset:

  • numerical 1D: [start,end]

  • numerical 2D with multiple ranges: [[start1,start2,start3],[end1,end2,end3]]

    • implicit: cursors(A, B) or [cursors(A, B), cursors(C, D)]

    • implicit: epochs([E0, TP])

    • implicit with offset calculcation: epochs(E0) + [1, -1]

  • named epoch: E0 or a as wildcard expression E* or multiple

If one dataset is returned, numRows == 1, all ranges will be used for all sweeps in the selection.

When multiple datasets are returned, numRows > 1, the i-th sweep will use all ranges from the i-th dataset. The number of sweeps and datasets also has to match.

Returns:

One or multiple datasets

wave SFH_GetRangeFromEpoch(string graph, string epochName, variable sweep, variable chanType, variable channel)

Returns a range from a epochName.

Parameters:

  • graph – name of databrowser graph

  • epochName – name epoch

  • sweep – number of sweep

  • chanType – type of channel

  • channel – number of DA channel

Returns:

a 1D wave with two elements, [startTime, endTime] in ms, if no epoch could be resolved [NaN, NaN] is returned

wave SFH_GetSweepsForFormula(string graph, WaveRefWave range, WaveOrNull selectData, string opShort)

Return a wave reference wave with the requested sweep data. The argument range can contain multiple datasets, if it is a single dataset the range(s) are extracted from each selection, if there are multiple datasets then the number of datasets must equal the number of selections, for that case range datasets and selections are indexed the same. This is usually only senseful if the same select arguments are used for e.g. data to retrieve sweeps and epochs to retrieve ranges.

All wave input parameters are treated as const and are thus not modified.

Parameters:

  • graph – name of databrowser graph

  • range – wave ref wave with range specification defining the x-range of the extracted data, see also SFH_EvaluateRange(), range specification per dataset can be numerical or text

  • selectData – channel/sweep selection, see also SFH_GetArgumentSelect()

  • opShort – operation name (short)

wave SFH_MoveDatasetHigherIfCompatible(WaveRefWave data)

Moves datasets from array elements to higher level e.g. [dataset(1, 2), dataset(3, 4)] -> dataset([1, 3], [3, 4]) e.g. [dataset(1, 2, 3), dataset(4, 5, 6)] -> dataset([1, 4], [2, 5], [3, 6]) e.g. [dataset(1, 2), dataset(4, 5), dataset(6, 7)] -> dataset([1, 4, 6], [2, 5, 7]) Requirements that this is possible are:

  • all initial array elements must resolve to datasets

  • all dataset waves of the initial array elements must be non-null, have the same size and must be 1d

  • all elements of these datasets must be non-null, have the same type and the same size and must be max 3d

  • only numeric and text is supported as type, thus the datasets may not contain datasets themselves If none of the requirements are met the input data is returned.
