Class BitwiseLeftShift

      com.esri.arcgis.geoprocessing.tools.spatialanalysttools.BitwiseLeftShift

All Implemented Interfaces:

GPTool

public class BitwiseLeftShift
extends AbstractGPTool

Performs a Bitwise Left Shift operation on the binary values of two input rasters. The Bitwise Left Shift tool is contained in the Spatial Analyst Tools tool box.

Usage tips:

• Two inputs (rasters or numbers) are necessary for the bitwise operation to take place.
• The order of inputs is relevant for this tool.
• In Bitwise operations:
  • Binary values are stored in two's complement.
  • The tools work on 32-bit integers.
  • The leftmost bit position is reserved for the sign of the value (positive or negative). If the integer is positive, the bit position is 0; if it's negative, the bit position is 1.
• The Bitwise Left Shift operation does no wrapping of bits. The leftmost bit is dropped.
• In Map Algebra, the equivalent symbol for this tool is "<<" ().

Constructor Detail

BitwiseLeftShift

public BitwiseLeftShift()

Creates the Bitwise Left Shift tool with defaults.

Initializes the array of tool parameters with the default values specified when the tool was created.

BitwiseLeftShift

public BitwiseLeftShift(Object inRasterOrConstant1,
                        Object inRasterOrConstant2,
                        Object outRaster)

Creates the Bitwise Left Shift tool with the required parameters.

Initializes the array of tool parameters with the values as specified for the required parameters and with the default values for the other parameters.

Parameters:

inRasterOrConstant1 - the input on which to perform the shift. a number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment. if the input is floating-point, the values are converted to integer values through truncation before the bitwise operation is performed.

inRasterOrConstant2 - the input defining the number of positions to shift the bits. a number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment. if the input is floating-point, the values are converted to integer values through truncation before the bitwise operation is performed.

outRaster - the output raster. the cell values are the result of a Bitwise Left Shift operation on the inputs.

Method Detail

getInRasterOrConstant1

public Object getInRasterOrConstant1()

Returns the Input raster or constant value 1 parameter of this tool . This parameter is the input on which to perform the shift. a number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment. if the input is floating-point, the values are converted to integer values through truncation before the bitwise operation is performed. This is a required parameter.

Returns:

the Input raster or constant value 1

setInRasterOrConstant1

public void setInRasterOrConstant1(Object inRasterOrConstant1)

Sets the Input raster or constant value 1 parameter of this tool . This parameter is the input on which to perform the shift. a number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment. if the input is floating-point, the values are converted to integer values through truncation before the bitwise operation is performed. This is a required parameter.

Parameters:

inRasterOrConstant1 - the input on which to perform the shift. a number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment. if the input is floating-point, the values are converted to integer values through truncation before the bitwise operation is performed.

getInRasterOrConstant2

public Object getInRasterOrConstant2()

Returns the Input raster or constant value 2 parameter of this tool . This parameter is the input defining the number of positions to shift the bits. a number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment. if the input is floating-point, the values are converted to integer values through truncation before the bitwise operation is performed. This is a required parameter.

Returns:

the Input raster or constant value 2

setInRasterOrConstant2

public void setInRasterOrConstant2(Object inRasterOrConstant2)

Sets the Input raster or constant value 2 parameter of this tool . This parameter is the input defining the number of positions to shift the bits. a number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment. if the input is floating-point, the values are converted to integer values through truncation before the bitwise operation is performed. This is a required parameter.

Parameters:

inRasterOrConstant2 - the input defining the number of positions to shift the bits. a number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment. if the input is floating-point, the values are converted to integer values through truncation before the bitwise operation is performed.
