GPTool

public class Append

extends AbstractGPTool

Appends multiple input dataset into an already existing target dataset. Input datasets can be point, line or polygon feature classes, tables, rasters or raster catalogs. The Append tool is contained in the Data Management Tools tool box.

Software restrictions: none

Illustration:

Usage tips:

• Use Append when you have an existing dataset into which you want to append new data. Input datasets can be point, line or polygon feature classes, tables, rasters or raster catalogs.
• When the inputs are features, all input features must be of the same feature type as the features of the target dataset. For example, if the target feature class contains polygon features, the input features types must be polygon as well.
• Input datasets may overlap one another and/or the target dataset.
• Input datasets in a different coordinate system from the target featureclass will be projected into the coordinate system of the target featureclass.
• Unlike the Union; function, Append does not planarize the input features into a single output. Input features from all the input feature classes remain intact in the target feature class.
• If the TEST option is specified, the field definitions of the feature classes must be the same and in the same order for all appended features.
• If the NO TEST option is selected, input features schemas do not have to match the target feature classe's schema. However, information in the input feature class's fields which do not match the target feature class's schema will not be carried into the target unless the FieldMap parameter is used.
• The Field Map parameter can only be usued if the NO TEST option is selected in the schema type parameter.
• When NO TEST is selected, the Field Map parameter can be used to control the output attribute content of input features. For example, consider the case where both the input and target feature classes have fields containing population information but the name of the fields are different (e.g. pop vs population). If you do not manipulate the FieldMap control features from the input featureclass will get a null value for the population field. Using the FieldMap, you can set the it such that the input features will get their values for the population field from the input pop field. For more information please see the How to Perform Field Mapping; help page.
• Current map layers may be used to define input features. When using layers, only the currently selected features are used in the Append operation.
• Append cannot use multiple input layers; of the same name. Although ArcMap allows for the display of layers with the same name (from different directories) these may not be used in the Append tool. For example, although c:\roads and d:\redlands\roads are two distinct datasets;
• Append does not perform edge matching. There will be no adjustment to the boundaries of features. Edge matching can be performed through ArcMap (or ArcINFO Workstation) only.

Constructor Detail

Append

public Append()

Creates the Append tool with defaults.

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

Append

public Append(java.lang.Object inputs,
              java.lang.Object target)

Creates the Append 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:

inputs - Table View | Raster Layer, the input point, line or polygon featureclasses or tables that will be appended into the target dataset.

target - Table View | Raster Layer, the existing output feature class, table, raster or raster catalog that will contain the appended input features.

Method Detail

getInputs

public java.lang.Object getInputs()

Returns the Input Datasets parameter of this tool . This parameter is Table View | Raster Layer, the input point, line or polygon featureclasses or tables that will be appended into the target dataset. This is a required parameter.

Returns:

the Input Datasets

setInputs

public void setInputs(java.lang.Object inputs)

Sets the Input Datasets parameter of this tool . This parameter is Table View | Raster Layer, the input point, line or polygon featureclasses or tables that will be appended into the target dataset. This is a required parameter.

Parameters:

inputs - Table View | Raster Layer, the input point, line or polygon featureclasses or tables that will be appended into the target dataset.

getTarget

public java.lang.Object getTarget()

Returns the Target Dataset parameter of this tool . This parameter is Table View | Raster Layer, the existing output feature class, table, raster or raster catalog that will contain the appended input features. This is a required parameter.

Returns:

the Target Dataset

setTarget

public void setTarget(java.lang.Object target)

Sets the Target Dataset parameter of this tool . This parameter is Table View | Raster Layer, the existing output feature class, table, raster or raster catalog that will contain the appended input features. This is a required parameter.

Parameters:
