public interface Sample

A sample represents the (geophysical) value of a RasterDataNode at a certain a certain pixel position.

This interface is not intended to be implemented by clients.

Since:

BEAM 4.9

Method Detail

getNode

RasterDataNode getNode()

Returns:

The raster data node to which this sample belongs.

getIndex

int getIndex()

Returns:

The index of the sample defined by the various SourceSampleConfigurer or TargetSampleConfigurer method and used within the sample arrays passed to computeSample() or computePixel() methods.

getDataType

int getDataType()

Returns:

The geophysical data type of this sample.

RasterDataNode.getGeophysicalDataType()

getBit

boolean getBit(int bitIndex)

Interprets an integer sample as a sequence of bits (flags).

Parameters:

bitIndex - The bit index. Valid range is zero to n-1, where n is 8, 16, 32, 64, depending on the actual raster data type.

Returns:

The sample value as bit at given bit index.

getBoolean

boolean getBoolean()

Returns:

The sample value as boolean.

getInt

int getInt()

Returns:

The sample value as int.

getFloat

float getFloat()

Returns:

The sample value as float.

getDouble

double getDouble()

Returns:

The sample value as double.
