```
public abstract class JPConverter
extends java.lang.Object
```
This class together with its embedded subclasses handles conversion from Java values to XPath values.
The general principle is to allocate a specific JPConverter at compile time wherever possible. If there is insufficient type information to make this feasible, a general-purpose JPConverter is allocated, which in turn allocates a more specific converter at run-time to do the actual work.

  - allocate
```
public static JPConverter allocate(java.lang.Class javaClass,
                                   java.lang.reflect.Type genericType,
                                   Configuration config)
```
    Allocate a Java-to-XPath converter for a given class of Java objects
    
    Parameters:
    
    javaClass - the class of the Java object to be converted (this may be the static type or the dynamic type, depending when the converter is allocated)
    
    genericType - the generic type of the Java object; may be null if unknown
    
    config - the Saxon Configuration
    
    Returns:
    
    a suitable converter
  - convert
```
public abstract Sequence convert(java.lang.Object object,
                                 XPathContext context)
                          throws XPathException
```
    Convert a Java object to an equivalent XPath value
    
    Parameters:
    
    object - the java object to be converted
    
    context - the XPath dynamic evaluation context
    
    Returns:
    
    the XPath value resulting from the conversion
    
    Throws:
    
    XPathException - if the conversion is not possible or if it fails
  - getItemType
```
public abstract ItemType getItemType()
```
    Get the item type of the XPath value that will result from the conversion
    
    Returns:
    
    the XPath item type
  - getCardinality
```
public int getCardinality()
```
    Get the cardinality of the XPath value that will result from the conversion
    
    Returns:
    
    the cardinality of the result
