THe path will exclude the one or more entities also identified by the specified data source code and record ID pairs that identify the composite records of the excluded entities and further will require the path contains at least one of the data sources identified by the one or more specified data sources codes.
    The excluded entities are identified by the data source codes and record ID's of their composite records in a JSON document with the following format:
    { "ENTITIES": [ { "DATA_SOURCE": "<data_source1>", "RECORD_ID": "<record_id1>" }, { "DATA_SOURCE": "<data_source2>", "RECORD_ID": "<record_id2>" }, . . . { "DATA_SOURCE": "<data_sourceN>", "RECORD_ID": "<record_idN>" } ] }
    
    The required set of data sources are identified by their data source codes in a JSON document with the following format:
    { "DATA_SOURCES": [ "<data_source_code1>", "<data_source_code2>", . . . "<data_source_codeN>" ] }
    Specified by:
    
    findPathIncludingSourceByRecordID in interface G2Engine
    
    Parameters:
    
    dataSourceCode1 - The data source code of the first record.
    
    recordID1 - The record ID of the first record.
    
    dataSourceCode2 - The data source code of the second record.
    
    recordID2 - The record ID of the second record.
    
    maxDegree - The maximum number of degrees for the path search.
    
    excludedEntities - The JSON document identifying the excluded entities via their entity ID's.
    
    requiredDsrcs - The JSON document identifying the data sources that must be included on the path.
    
    flags - The flags to control how the operation is performed and specifically the content of the response JSON document.
    
    response - The StringBuffer to write the JSON response document to.
    
    Returns:

    Processes a redo record.
    
    Specified by:
    
    processRedoRecordWithInfo in interface G2Engine
    
    Parameters:
    
    flags - The flags to control how the operation is performed and specifically the content of the response JSON document.
    
    record - A returned JSON document containing the info.
    
    response - A StringBuffer for returning the response document. If an error occurred, an error response is stored here.
    
    Returns:
    
    Zero (0) on success and non-zero on failure.
  - getRedoRecord
```
public int getRedoRecord(StringBuffer record)
```
    Retrieves a pending redo record from the reevaluation queue.
    
    Specified by:
    
    getRedoRecord in interface G2Engine
    
    Parameters:
    
    record - A StringBuffer to write the redo record to.
    
    Returns:
    
    Zero (0) on success and non-zero on failure.
  - countRedoRecords
```
public long countRedoRecords()
```
    Gets the number of redo records waiting to be processed.
    
    Specified by:
    
    countRedoRecords in interface G2Engine
    
    Returns:
    
    The number of redo records waiting to be processed.
  - process
```
public int process(String record)
```
    This method will send a record for processing in g2. It is a synchronous call, i.e. it will wait until g2 actually processes the record. This is similar to G2Engine.process(String,StringBuffer) method, but this variant does not return a response. NOTE: there are performance benefits of calling this variant of process that does not require a response.
    
    Specified by:
    
    process in interface G2Engine
    
    Parameters:
    
    record - An input record to be processed.
    
    Returns:
    
    Zero (0) on success and non-zero on failure.
  - process
```
public int process(String record,
                   StringBuffer response)
```
    This method will send a record for processing in g2. It is a synchronous call, i.e. it will wait until g2 actually processes the record, and then return a response message. This is similar to G2Engine.process(String) method, but this variant returns a response. NOTE: there are performance benefits of calling the variant of process that does not require a response.
    
    Specified by:
    
    process in interface G2Engine
    
    Parameters:
    
    record - An input record to be processed.
    
    response - A StringBuffer for returning the response document.
    
    Returns:
    
    Zero (0) on success and non-zero on failure.
  - processWithInfo
```
public int processWithInfo(String record,
                           int flags,
                           StringBuffer response)
```
    This method will send a record for processing in g2. It is a synchronous call, i.e. it will wait until g2 actually processes the record. This is similar to G2Engine.process(String,StringBuffer) method, but this variant does not return a response. NOTE: there are performance benefits of calling this variant of process that does not require a response. Also returns a list of modified resolved entities
    
    Specified by:
    
    processWithInfo in interface G2Engine
    
    Parameters:
    
    record - An input record to be processed.
    
    flags - The flags to control how the operation is performed and specifically the content of the response JSON document.
    
    response - A StringBuffer for returning the response document. If an error occurred, an error response is stored here.
    
    Returns:
    
    Zero (0) on success and non-zero on failure.
