public class CBlkWTDataFloat
extends CBlkWTData

This is an implementation of the 'CBlkWTData' abstract class for 32 bit floating point data (float).

The methods in this class are declared final, so that they can be inlined by inlining compilers.

Method Detail

getDataType

public final int getDataType()

Returns the identifier of this data type, TYPE_FLOAT, as defined in DataBlk.

Specified by:

getDataType in class CBlkWTData

Returns:

The type of data stored. Always DataBlk.TYPE_FLOAT

See Also:

DataBlk.TYPE_FLOAT

getData

public final Object getData()

Returns the array containing the data, or null if there is no data array. The returned array is a float array.

Specified by:

getData in class CBlkWTData

Returns:

The array of data (a float[]) or null if there is no data.

See Also:

CBlkWTData.getDataType()

getDataFloat

public final float[] getDataFloat()

Returns the array containing the data, or null if there is no data array.

Returns:

The array of data or null if there is no data.

setData

public final void setData(Object arr)

Sets the data array to the specified one. The provided array must be a float array, otherwise a ClassCastException is thrown. The size of the array is not checked for consistency with the code-block dimensions.

Specified by:

setData in class CBlkWTData

Parameters:

arr - The data array to use. Must be a float array.

See Also:

CBlkWTData.getDataType()

setDataFloat

public final void setDataFloat(float[] arr)

Sets the data array to the specified one. The size of the array is not checked for consistency with the code-block dimensions. This method is more efficient than 'setData()'.

Parameters:

arr - The data array to use.
