Class SetNull

      com.esri.arcgis.geoprocessing.tools.spatialanalysttools.SetNull

All Implemented Interfaces:

GPTool

public class SetNull
extends AbstractGPTool

Set Null sets identified cell locations to NoData based on a specified criteria. It returns NoData if a conditional evaluation is true, and returns the value specified by another raster if it is false. The Set Null tool is contained in the Spatial Analyst Tools tool box.

Usage tips:

• If the evaluation of the where clause is true, the cell location on the output raster will be assigned NoData. If the evaluation is false, the output raster will be defined by the input false raster or constant value.
• If no where clause is specified, the output raster will have NoData wherever the conditional raster is greater than zero.
• The input conditional raster does not affect whether the output data type is integer or floating point. If the input false raster or constant value contains floating-point values, the output raster will be floating point. If it contains all integer values, the output will be an integer raster.

Constructor Detail

SetNull

public SetNull()

Creates the Set Null tool with defaults.

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

SetNull

public SetNull(Object inConditionalRaster,
               Object inFalseRasterOrConstant,
               Object outRaster)

Creates the Set Null 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:

inConditionalRaster - input raster representing the true or false result of the desired condition. it must be of integer type.

inFalseRasterOrConstant - input holding the value that will be used as the output value if the condition is false. it can be an integer or a floating point raster, or a constant value.

outRaster - the output raster. if the conditional evaluation is true, NoData is returned. If false, the value of the second input raster is returned.

Method Detail

getInConditionalRaster

public Object getInConditionalRaster()

Returns the Input conditional raster parameter of this tool . This parameter is input raster representing the true or false result of the desired condition. it must be of integer type. This is a required parameter.

Returns:

the Input conditional raster

setInConditionalRaster

public void setInConditionalRaster(Object inConditionalRaster)

Sets the Input conditional raster parameter of this tool . This parameter is input raster representing the true or false result of the desired condition. it must be of integer type. This is a required parameter.

Parameters:

inConditionalRaster - input raster representing the true or false result of the desired condition. it must be of integer type.

getInFalseRasterOrConstant

public Object getInFalseRasterOrConstant()

Returns the Input false raster or constant value parameter of this tool . This parameter is input holding the value that will be used as the output value if the condition is false. it can be an integer or a floating point raster, or a constant value. This is a required parameter.

Returns:

the Input false raster or constant value

setInFalseRasterOrConstant

public void setInFalseRasterOrConstant(Object inFalseRasterOrConstant)

Sets the Input false raster or constant value parameter of this tool . This parameter is input holding the value that will be used as the output value if the condition is false. it can be an integer or a floating point raster, or a constant value. This is a required parameter.

Parameters:

inFalseRasterOrConstant - input holding the value that will be used as the output value if the condition is false. it can be an integer or a floating point raster, or a constant value.

getOutRaster

public Object getOutRaster()
