Geoprocessor object
Release 9.2 Last modified November 7, 2007	Print all topics in : "Scripting object: Properties and Methods"

Scripting is the ability to use the geoprocessor functions from any number of current scripting environments, such as Python, VBScript, JScript, and Perl. A new ArcObjects component, the geoprocessor object, will be the main vehicle for exposing the geoprocessing functions to the scripting languages. It is an object that provides a single access point and environment for the execution of any geoprocessing tool in ArcGIS, including extensions.

The geoprocessor object methods and properties exposed for scripting and command line usage. They do not exist as tools in any toolbox.

For further information about scripting, its uses within a GIS, which scripting language to use, as well as additional samples, see An overview of writing geoprocessing scripts.

A - F

Expression	Explanation
AddError	Adds a return message of severity=2 to the queue.
AddMessage	Adds a return message of severity=0 to the queue.
AddReturnMessage	Adds a message, from the function message queue, to the return queue.
AddToolbox	Gets the specified toolbox and exposes its functionality.
AddWarning	Adds a return message of severity=1 to the queue.
CheckExtension	Checks license availability of a specific type of extension.
CheckInExtension	Returns the license to the License Manager so other applications can use it.
CheckOutExtension	Retrieves the license for a specific type of extension.
CheckProduct	Checks which desktop licenses are available.
ClearEnvironment	Resets a specific environment setting to its default.
Command	Parses the specified command line as a string.
CopyParameter	Copies the selected parameter definition to the specified parameter list.
CreateObject	Specifies the geoprocessor object model object to be created.
CreateRandomValueGenerator	Returns an object that is used to create random values.
CreateScratchName	Creates a scratch pathname of the given data type.
CreateUniqueName	Creates a unique name.
Describe	Describes such properties as type, name, spatial reference, domains, versioning for DataElements such as FeatureClasses, Tables, GeoDatasets, CoverageFeatureClasses, Datasets, RelationshipClasses, Files, Layers, Workspaces, as well as geoprocessing objects such as TableViews and FeatureLayers.
Exists	Tests if the specified input exists and returns a Boolean value.

G - L

Expression	Explanation
GetMessage	Gets the specified message descriptions that were returned.
GetMessages	Gets all message descriptions that were returned.
GetParameter	Selects the specified parameter, by its index position, from the list of parameters. This method returns an object.
GetParameterAsText	Selects the specified parameter, by its index position, from the list of parameters. This method returns a string.
GetParameterCount	Returns the parameter count of a tool.
GetParameterValue	Returns a tool's parameter default value.
GetReturnCode	For the specified message index, where the severity=2, the error code is returned.
GetSeverity	Returns the severity of the message of the given index (0=ok, 1=warning, 2=error).
GetSystemEnvironment	Gets the specified system environment variable.
InsertCursor	Insert rows into a table or feature class. This method will return a Dispatch enumeration object that will, in turn, hand out Dispatch row objects.
IsSynchronous
ListDatasets	Lists all datasets that fit the search criteria. Specifying search conditions (wild card) and a feature type will limit the results.
ListEnvironments	Lists all environment settings that fit the search criteria. Specifying search conditions (wild card) will limit the results.
ListFeatureClasses	Lists all feature classes from the selected workspace. Specifying search conditions (wild card) and a feature type will limit the results.
ListFields	List all the fields in the specified table, feature class, or shapefile. Specifying search conditions (wild card) and a field type will limit the results.
ListIndexes	List all the indexes in the specified table, feature class, or shapefile. Specifying search conditions (wild card) will limit the results.
ListRasters	Lists all rasters from the selected workspace. Specifying search conditions (wild card) and a feature type will limit the results.
ListTables	Lists all tables from the selected workspace. Specifying search conditions (wild card) and a table type will limit the results.
ListToolboxes	Lists all toolboxes that fit the search criteria. Specifying search conditions (wild card) will limit the results.
ListTools	Lists all tools that fit the search criteria. Specifying search conditions (wild card) will limit the results.
ListWorkspaces	Lists any workspaces within the selected workspace. Specifying search conditions (wild card) and a workspace type will limit the results.
LoadSettings	Load environment settings from an XML environment settings file.

M - R

Expression	Explanation
MaxSeverity	Sets the maximum severity.
MessageCount	Returns a numeric count of all the returned messages from the last executed command.
OverWriteOutput	Allows or restricts the overwriting of existing outputs.
ParameterCount	The number of parameters returned.
ParseFieldName	Truncates a portion of the specified field name.
ParseTableName	Truncates a portion of the specified table name.
ProductInfo	Reports what the current product license is.
QualifyFieldName	Prefixes a field name string with the <database>.<username> if required.
QualifyTableName	Prefixes a table name string with the <database>.<username> if required.
RefreshCatalog	Refreshes ArcCatalog's catalog tree.
RemoveToolbox	Removes access to named toolbox for this current session.
ResetEnvironments	Resets all environment settings to their default settings.

S - Z

Expression	Explanation
SaveSettings	Save senvironment settings to an XML environment settings file.
SearchCursor	Establishes a cursor for searching through field rows. This method will return a Dispatch enumeration object that will, in turn, hand out Dispatch row objects.
SetParameter	Sets the specified parameter property using an object. The set parameter is selected from the existing parameter list by its index.
SetParameterAsText	Sets the specified parameter property using a string. The set parameter is selected from the existing parameter list by its index.
SetProduct	Defines the desktop license used by a script.
TestSchemaLock	Tests if a schema lock can be acquired for a table, feature class, or feature dataset. A number of tools require a schema lock on the input data because they alter the data’s schema. The Add Field tool is an example of such a tool. If a tool requires a schema lock and it cannot acquire one at the time of execution, an appropriate error message is returned. The method does not actually apply the schema lock.
Toolbox	Specifies the toolbox for the current geoprocessing session.
UpdateCursor	Positionally update and delete rows in a table.
Usage	Displays the syntax for the specified function.
ValidateFieldName	Returns a valid field name based on name restrictions present in the output geodatabase.
ValidateTableName	Returns a valid table name based on name restrictions present in the output geodatabase.
