==SetDataAggregation==
==SetDataAggregation==
'''Optional'''. This function enables/disables all forms of aggregation and value gathering. Any statistic that cannot be determined incrementally (for example, median, population standard deviation, etc.) is determined via aggregation. This analysis is also responsible for all value tables (Frequency, Pattern, SoundEx, etc.). All iterators and data aggregation statistics are dependent on this analysis. This increase profiling time by over 90%. These statistics are usually useful enough to justify the increased profiling time.

The following functions set the paths to the necessary data files, the license, and initialize the Profiler Interface:
==SetLicenseString==
This function sets the license string required to enable Profiler Object’s complete functionality.
The License String is a software key that unlocks the full functionality of the component. Without the License String, the object will only function in DEMO mode
The license string is normally set using an environment variable, either MD_LICENSE or MD_LICENSE_DEMO. Calling '''SetLicenseString''' is an alternative method for setting the license string, but applications developed for a production environment should only use the environment variable. When using an environment variable, it is not necessary to call the '''SetLicenseString''' function. For more information on setting the environment variable, see [[Profiler Object:Licensing|Licensing]].
This function accepts one parameter.
===Parameters===
{{Object Parameters
|Name=LicenseString
|Data Type=String
|Description=A string value representing the software license key.
}}
===Return Value===
The '''SetLicenseString''' function returns value of 0 or 1. A value of 0 means that the provided License String is incorrect.
{{ Object Syntax
|Syntax=profiler->SetLicenseString(StringValue);
|C=integer = mdProfilerSetLicenseString(profiler, LicenseString);
|.Net=integer = profiler.SetLicenseString(LicenseString);
}}
==SetPathToProfilerDataFiles==
This function sets the the path to the data files required for profiling.
The required data files are
*mdProfiler.dat
*mdProfiler.mc
This function accepts one Parameter.
===Parameters===
{{Object Parameters
|Name=LocationString
|Data Type=String
|Description=A string value representing the location of the Profiler data files.

}}
{{ Object Syntax
|Syntax=profiler->SetFileName(StringValue);
|C=mdProfilerSetFileName(profiler, FileNameString);
|.Net=profiler.SetFileName(FileNameString);
}}
==SetAppendMode==
'''Optional'''. This function sets the mode for how the output file needs to be handled. The default is overwrite mode if this function is not called.
If a Profiler file is opened in append mode certain statistics will not be accurate, as some results cannot be carried over from run to run. Specifically: TableExactMatch, TableContactMatch, TableHouseholdMatch,TableAddressMatch, ColumnInferredDataType, ColumnSortation, and ColumnSortationPercent.
If you intend to open the file in Append mode, you will want to call '''[[#SetSortAnalysis|SetSortAnalysis]]''', '''[[#SetMatchUpAnalysis|SetMatchUpAnalysis]]''' and '''[[#SetRightFielderAnalysis|SetRightFielderAnalysis]]''' appropriately.
The '''SetAppendMode''' function takes a value of the enumerated type '''AppendMode'''.

The following functions set the paths to the necessary data files, the license, and initialize the Profiler Interface:

SetLicenseString

This function sets the license string required to enable Profiler Object’s complete functionality.

The License String is a software key that unlocks the full functionality of the component. Without the License String, the object will only function in DEMO mode

The license string is normally set using an environment variable, either MD_LICENSE or MD_LICENSE_DEMO. Calling SetLicenseString is an alternative method for setting the license string, but applications developed for a production environment should only use the environment variable. When using an environment variable, it is not necessary to call the SetLicenseString function. For more information on setting the environment variable, see Licensing.

This function accepts one parameter.

Parameters

Name Data Type Description
LicenseString String A string value representing the software license key.

Return Value

The SetLicenseString function returns value of 0 or 1. A value of 0 means that the provided License String is incorrect.

Syntax profiler->SetLicenseString(StringValue);
C integer = mdProfilerSetLicenseString(profiler, LicenseString);
.Net integer = profiler.SetLicenseString(LicenseString);


SetPathToProfilerDataFiles

This function sets the the path to the data files required for profiling.

The required data files are

  • mdProfiler.dat
  • mdProfiler.mc

This function accepts one Parameter.
