Method Detail

parseStringInfestedFloatArray

public static int parseStringInfestedFloatArray(java.lang.String str,
                                                BitSet bs,
                                                float[] data)

parses a "dirty" string for floats. If there are non-float tokens, they are ignored. A bitset is used to assign values only to specific atoms in the set, not changing the values of the data array for other atoms. thus, a data set can be incrementally added to in this way.

Parameters:

str - the string to parse

bs - the atom positions to assign

data - the (sparce) array to fill

Returns:

number of floats

parseFloatArray

public static float[] parseFloatArray(java.lang.String str)

parseFloatArrayNext

public static float[] parseFloatArrayNext(java.lang.String str,
                                          int[] next)

Parameters:

str -

next -

Returns:

array of float values

parseFloatArrayBsData

public static int parseFloatArrayBsData(java.lang.String[] tokens,
                                        BitSet bs,
                                        float[] data)

parseFloatArray2d

public static float[][] parseFloatArray2d(java.lang.String str)

parseFloatArray3d
