Method Detail

parseDataArray

public static Number[] parseDataArray(Node dataArrayNode,
                                      XPath xpath)
                               throws XPathExpressionException,
                                      DataFormatException,
                                      IOException

Parses a node and returns an array of Numbers of the correct type (specified by the "type" attribute). This assumes that binary data is compressed with zlib, and uses Little Endian byte order. Supports "ascii" and "binary" formats, and "Float32" and "Int32" data types.

Parameters:

dataArrayNode - The Node in the DOM

xpath - An XPath object to evaluate expressions with. This will have already been created when finding the Node, so there is no point instantiating a new one for this class

Returns:

An array of Numbers

Throws:

DataFormatException

IOException

XPathExpressionException

parseDataArray

public static Number[] parseDataArray(Node dataArrayNode,
                                      XPath xpath,
                                      float[] fillVals)
                               throws DataFormatException,
                                      IOException,
                                      XPathExpressionException

Parses a node and returns an array of Numbers of the correct type (specified by the "type" attribute). This assumes that binary data is compressed with zlib, and uses Little Endian byte order. Supports "ascii" and "binary" formats, and "Float32" and "Int32" data types.

Parameters:

dataArrayNode - The Node in the DOM

xpath - An XPath object to evaluate expressions with. This will have already been created when finding the Node, so there is no point instantiating a new one for this class

fillVals - An array of values which are considered to be fill values. These will be returned as nulls.

Returns:

An array of Numbers

Throws:

DataFormatException

IOException

XPathExpressionException

parseDataString

public static Number[] parseDataString(String data,
                                       String format,
                                       String type,
                                       float[] fillVals)
                                throws DataFormatException,
                                       IOException
