Class DataSetBuilder

  • public class DataSetBuilder
extends java.lang.Object
    Helps allocating new DataSets in a flexible and efficient way. Values, Errors and Metadata can be added along with requirements for the resulting DataSet. Values are automatically converted between float and double if needed.

    Currently the builder generates the following DataSet types:

      • setInitalCapacity

        public DataSetBuilder setInitalCapacity​(int... newInitialCapacity)
        Sets the initial size of the dataset. A value for each dimension can be specified. If the number of dimensions exceeds the given sizes, the last one will be used. This means, that you can use a single value for a data set with the same number of data points in each dimension.
        Parameters:
        newInitialCapacity - varArgs sizes for the first n dimensions
        Returns:
        itself for method chaining
