Description 

getDocError 

Each time getNextDoc() is called, wasDocError will return true if there was an error processing the previous document, such as a file parsing error, and getDocError() will return the error message. 

getDocId 

Each time getNextDoc() is called, getDocId() will return the doc id of the last document indexed. A doc id can be used to identify a document in a SearchFilter. 

getDocTypeId 

Each time getNextDoc() is called, getDocTypeId() will return an integer identifying the file type of the last document indexed

haveDocBytes 

 

setDocBytes 

Use setDocBytes to provide an array of bytes for dtSearch to use as the binary contents of this document. To tell dtSearch to check for an array of bytes, tshe data source must return true from haveDocBytes().
The calling program should call setDocBytes to provide the binary contents of a file to be indexed before returning from getNextDoc().
While getDocText() can only return a stream of plain text, setDocBytes can return any type of binary data, such as the contents of a Word document or a PDF file. 

wasDocError 

Each time getNextDoc() is called, wasDocError() will return true if there was an error processing the previous document, such as a file parsing error, and getDocError() will return the error message.
