pyworkflow.utils.dataset module¶

# JMRT (2018-12-11) This module is almost not used at all. Maybe it can be removed in a future. Just kept here for the moment inside pw.utils and not imported by default

class pyworkflow.utils.dataset.Column(colName, colType=None, default=None, label=None, renderType=0)[source]¶

Bases: object

convert(value)[source]¶: Try to convert the value to the column type.

getDefault()[source]¶

getLabel()[source]¶

getName()[source]¶

getRenderType()[source]¶

getType()[source]¶

hasDefault()[source]¶

setRenderType(renderType)[source]¶

class pyworkflow.utils.dataset.DataSet(tables, tableName=None, volumeName=None, numberSlices=0)[source]¶

Bases: object

Holds several Tables All tables should have an unique tableName.

currentTable()[source]¶: Returns the name of the last selected table.

getNumberSlices()[source]¶

getNumberSlicesForTemplate()[source]¶

getTable(tableName=None)[source]¶

getTypeOfColumn(label)[source]¶: this method should be implemented by subclasses.

getVolumeName()[source]¶

listTables()[source]¶: List the actual table names on the DataSet.

setNumberSlices(numberSlices)[source]¶

setVolumeName(volumeName)[source]¶

class pyworkflow.utils.dataset.SingleFileDataSet(filename)[source]¶

Bases: pyworkflow.utils.dataset.DataSet

DataSet implementation for single files such as Images or Volumes.

class pyworkflow.utils.dataset.SqliteDataSet(filename)[source]¶

Bases: pyworkflow.utils.dataset.DataSet

Provide a DataSet implementation based on sqlite file. The tables of the dataset will be the object tables in database. Each block is a table on the dataset.

class pyworkflow.utils.dataset.Table(*columns)[source]¶

Bases: object

Table to hold rows of data. A table contains a list of columns.

addRow(rowId, **values)[source]¶: With this implementation the rowId should be provided. We need to work around to also allow automatic generation of id’s

getColumn(columnName)[source]¶

getColumnValues(columnName)[source]¶

getColumns()[source]¶: Return all columns.

getDataToRender()[source]¶

getDataToRenderAndExtra()[source]¶

getIdColumn()[source]¶

getIndexFromValue(value, label)[source]¶: Search the element that has property ‘label’ equals to value and returns its index.

getNumberOfColumns()[source]¶

getRow(rowId)[source]¶

getRows()[source]¶: Return all rows.

getSize()[source]¶: Return the number of rows.

getTransformationMatrix()[source]¶

getValueFromIndex(index, label)[source]¶: Return the value of the property ‘label’ in the element that has this ‘index’.

hasColumn(columnName)[source]¶: Return true if column exists

hasEnabledColumn()[source]¶: Return true if enabled column exists

iterColumns()[source]¶

iterRows()[source]¶: Iterate over the rows.

setLabelToRender(labelToRender)[source]¶

updateRow(rowId, **values)[source]¶: Update a row given its rowId and some values to update.
