ScannerFactory

java.lang.Object
- org.simpleframework.xml.core.ScannerFactory

```
class ScannerFactory
extends java.lang.Object
```
The ScannerFactory is used to create scanner objects that will scan a class for its XML class schema. Caching is done by this factory so that repeat retrievals of a Scanner will not require repeat scanning of the class for its XML schema.

public ScannerFactory(Support support)
```
    Constructor for the ScannerFactory object. This is used to create a factory that will create and cache scanned data for a given class. Scanning the class is required to find the fields and methods that have been annotated.
    
    Parameters:
    
    support - this is used to determine if a type is primitive
- Method Detail
  - getInstance
```
public Scanner getInstance(java.lang.Class type)
                    throws java.lang.Exception
```
    This creates a Scanner object that can be used to examine the fields within the XML class schema. The scanner maintains information when a field from within the scanner is visited, this allows the serialization and deserialization process to determine if all required XML annotations are used.
    
    Parameters:
    
    type - the schema class the scanner is created for
    
    Returns:
    
    a scanner that can maintains information on the type
    
    Throws:
    
    java.lang.Exception - if the class contains an illegal schema
