Collection
SalienceCollection
Summary
The constructor instantiates a SalienceCollection object which provides access to collection-level API functionality. For document-level functionality, a Salience object should be instantiated.
The constructor provides a wrapper around the underlying C API methods lxaLoadLicense and lxaOpenSalienceSession.
Syntax
SalienceCollection(string sLicensePath, string sDataPath)
SalienceCollection(string sLicensePath, string sDataPath, string sUserDir)
SalienceCollection(string sLicensePath, string sDataPath, string sUserDir, string sLogPath)
SalienceCollection(string sLicensePath, SalienceStartup oStartup)
Parameters
| String containing the path to the required license file |
|---|---|
| String containing the path to the data directory to use for the session |
| String containing the path to a user directory of data file customizations |
| String containing the path to writable location for a startup log |
| A SalienceStartup object containing startup information for the session |
Returns
If successful, the constructor returns a SalienceCollection object that can be used for processing a related set of text. Otherwise, an exception is thrown with information about the failure of the constructor.

SalienceCollection.GetSalienceVersion
Summary
Gets the version of the library. You can use this to display a version of the underlying Salience Engine in use. This is a wrapper around the underlying C API method lxaGetSalienceVersion.
Syntax
public string GetSalienceVersion()
Parameters
None
Returns
A string containing the version of the underlying Salience Engine library.

SalienceCollection.DumpEnvironment
Summary
Outputs environment information about the SalienceCollection session. This includes the data directory and user directory in use, as well as the value of any options that have been set.
This is a wrapper around the underlying C API method lxaDumpEnvironment.
Syntax
public string DumpEnvironment()
Parameters
None
Returns
A string containing the parameters of the operating environment of the current Salience session.
Example
//The SalienceEngine object wraps all of the Salience functionality
//and must be initialized to use the library.
SalienceCollection Engine = null;
//If this application will be run on multiple machines, it may be helpful to read these paths
//from a configuration file or a registry key to avoid introducing dependencies on where the
//license and data must be installed.
string licensePath = "C:/Program Files/Lexalytics/License.v5";
string dataPath = "C:/Program Files/Lexalytics/data";
try
{
//We declared Engine before initializing it so we could put this in a try/catch block, and
//have the rest of the code outside.
Engine = new SalienceCollection(licensePath, dataPath);
}
catch (SalienceException e)
{
/*If the SalienceEngine constructor throws an error, one of these is likely to be true:
* 1) The license file is missing/invalid/out of date
* 2) The data directory was missing or contained incorrect files
* 3) Salience6.dll could not be found. */

SalienceCollection.AddSalienceConfiguration
Summary
Supports the analysis of content through multiple user directories.
This method adds the specified user directory, with the customizations and tuning it contains, to the specified Salience session. After adding a configuration to the Salience session, additional processing options and results from various API methods can be retrieved by using the identifier provided in configurationID.
Calling this method with a value for configurationID that has been previously added will result in an error code returned.
This is a wrapper around the underlying C API method lxaAddSalienceConfiguration.
Syntax
public void AddSalienceConfiguration(String userDir, String configurationID)
Parameters
| Path to a user directory to use for this configuration |
|---|---|
| String specifying a unique identifier for this configuration |
Returns
Integer return code. LXA_OK indicates success, LXA_CONFIG_IN_USE indicates the provided configuration ID has already been added to the session.
SalienceCollection.RemoveSalienceConfiguration
Summary
This method removes the specified configuration from those used in processing content in the the current Salience session.
Calling this method with a value for configurationID that has not been previously added by a call to SalienceCollection.AddSalienceConfiguration will result in an error code returned. Additionally, calling this method with an empty string (which identifies the default configuration) will result in an error.
This is a wrapper around the underlying C API method lxaRemoveSalienceConfiguration.
Syntax
public void RemoveSalienceConfiguration(String configurationID)
Parameters
| Character string specifying a unique identifier for a configuration previously added to the session |
|---|
Returns
Integer return code. LXA_OK indicates success, LXA_INVALID_CONFIG indicates the provided configuration ID has already been added to the session, also returned if this method is called with an empty string for configurationID.
SalienceCollection.PrepareTextFromList
Summary
Provides a set of related pieces of content to Salience 6 for collection-level analysis. This method, or PrepareCollectionFromFile must be called for each new group of content that should be analyzed. The text provided in the set must be 7bit ASCII or valid UTF-8.
This method is a a wrapper around the underlying C API method lxaPrepareCollection.
Syntax
public int PrepareCollectionFromList(string sName, List<String> lstText)
Parameters
| A descriptive name for the collection |
|---|---|
| A List<> structure of strings, each representing a unique piece of content within the set. |
Returns
If successful, an integer return code is returned. Developers should check the integer return code to determine if warnings were issued. Otherwise, an exception is thrown with information about the failure of text preparation.
Example

public int PrepareCollectionFromFile(string sName, string sFile)
Parameters
| A descriptive name for the collection |
|---|---|
