Method Detail

setDataBufferData

public final void setDataBufferData(double[] v)

Sets the vector in the DataBuffer to the values in the input. Data may be cast and lose precision in the copy process. This method should fire a PropertyChangeEvent when the buffer data are changed

Parameters:

v - a double[] which will be deep copied to a Double[] as the data buffer

setDataBufferData

public final void setDataBufferData(int[] v)

Sets the vector in the DataBuffer to the values in the input. Data may be cast and lose precision in the copy process. This method should fire a PropertyChangeEvent when the buffer data are changed

Parameters:

v - an int[] which will be deep copied to a Double[] as the data buffer

setDataBufferData

public final void setDataBufferData(java.util.AbstractList<? extends java.lang.Number> v)

Sets the vector in the DataBuffer to the values in the input. Data may be cast and lose precision in the copy process. This method should fire a PropertyChangeEvent when the buffer data are changed

Parameters:

v - an AbstractList, values from which which will be deep copied to a Double[] as the data buffer. Precision will be lost if the AbstractList contains data such a BigDecimal or Long.

setEntry

public final void setEntry(int index,
                           double val)

Description copied from interface: GJDataVectorInterface

Sets a value in the DataBuffer This method should fire a PropertyChangeEvent when the buffer data are changed

val - the new value as double

setEntry

public final void setEntry(int index,
                           java.lang.Double val)

getDataValues

public final double[] getDataValues(GJDataTransformInterface transform)

Returns the data as an IEEE double precision array transformed by the class specified by getTranform

Returns:

a double[]

getRawDataValues

public final double[] getRawDataValues()

Returns the data as an IEEE double precision array without applying a transform

Returns:

a double[]

getDimension

public final int getDimension()

Length of the vector in the DataBuffer

Returns:

the length of the vector
