A custom tool is represented by a class deriving from the base class GdkTool.

Once a class has been defined and registered with the project assembly, it will be automatically discovered by the framework and become available for use just like a built-in tool.

The following aspects of a tool can be controlled:

Name
Type
Configuration parameters
List of measurements
Visualization
Acceptable data type

During boot-up, the framework calls the GoTool_Describe static method on each tool class. The implementation of this method should describe the tool using the given GdkToolInfo object.

At a minimum, a tool should describe its type name, data type, acceptable source options and at least one measurement.

GdksFx(kStatus) GdksTestRawTool_VDescribe(GdkToolInfo toolInfo)
{
    kCheck(GdkToolInfo_SetTypeName(toolInfo, "TestTool"));
    kCheck(GdkToolInfo_SetSourceType(toolInfo, GT_DATA_TYPE_UNIFORM_PROFILE));
    kCheck(GdkToolInfo_AddSourceOption(toolInfo, GT_DATA_SOURCE_TOP));
    kCheck(GdkToolInfo_AddMeasurement(toolInfo, "X", kNULL));
    return kOK;
}
