      • isValidValue

        public boolean isValidValue​(org.nd4j.linalg.api.ndarray.INDArray value)
        Validates whether a INDArray conforms to this time series. An INDArray confirms to this value, if its rank is 1 and its length equals the length of this time series.
        Specified by:
        isValidValue in interface IAttributeType<org.nd4j.linalg.api.ndarray.INDArray>
        Parameters:
        value - The value to validated.
        Returns:
        Returns true if the given value conforms

      • buildAttributeValue

        public IAttributeValue<org.nd4j.linalg.api.ndarray.INDArray> buildAttributeValue​(java.lang.Object value)
        Description copied from interface: IAttributeType
        Casts the value to the respective type and returns an attribute value with the creating attribute type as the referenced type.
        Specified by:
        buildAttributeValue in interface IAttributeType<org.nd4j.linalg.api.ndarray.INDArray>
        Parameters:
        value - The value of the attribute.
        Returns:
        An attribute value object holding the value of the attribute and referring to this attribute type.

      • buildAttributeValue

        public IAttributeValue<org.nd4j.linalg.api.ndarray.INDArray> buildAttributeValue​(java.lang.String stringDescription)
        Description copied from interface: IAttributeType
        Builds an attribute value object from a string description. The attribute value references this attribute type.
        Specified by:
        buildAttributeValue in interface IAttributeType<org.nd4j.linalg.api.ndarray.INDArray>
        Parameters:
        stringDescription - A String-format description of the attribute's value.
        Returns:
        The attribute value object holding an attribute value interpreting the string description and referring to this attribute type.

      • getLength

        public int getLength()
        Get the length of this time series attribute type.
        Returns:
        The length respec. the number of datapoints of this time series attribute.

      • setLength

        public void setLength​(int length)
