Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`load(InputStream geneInputStream, String taxonName)`
`int`	`load(String geneFile, String taxonName)`	Work flow is: The file is first checked to see if readable, and the taxon checked to see it is in Gemma.

- Method Detail
  - load
```
int load(String geneFile,
         String taxonName)
  throws Exception
```
    Work flow is: The file is first checked to see if readable, and the taxon checked to see it is in Gemma. If validation passes the file is read line by line. Each line equates to a gene and its gene product, which is created from the file details. The gene is then persisted. If successfully loaded taxon flag isGenesLoaded is set to true to indicate that there are genes loaded for this taxon.
    
    Parameters:
    
    geneFile - Full path to file containing genes details
    
    taxonName - taxonName to be associated to this gene, does not have to be a species.
    
    Returns:
    
    number of genes loaded
    
    Throws:
    
    Exception - Thrown with a file format error or problem in persisting gene to database.
  - load
```
int load(InputStream geneInputStream,
         String taxonName)
  throws Exception
```
    Parameters:
    
    geneInputStream - gene input stream
    
    taxonName - taxon name
    
    Returns:
    
    number of genes loaded
    
    Throws:
    
    Exception - Thrown with a file format error or problem in persisting gene to database.
