Method Detail

getComponentInstance

protected Object getComponentInstance(String className,
                                      Object object,
                                      String pattern)
                               throws ConversionException

Gets a large object instance converted from a source object. The source object may be a string representation of a file path, URL path, File instance, URL instance, byte buffer, char buffer, input stream or reader. The object is passed as a paramter to the LOB factory's instance constructor.

Overrides:

getComponentInstance in class DefaultObjectConverter<Object>

Parameters:

className - the name of the class.

object - the source object.

pattern - the conversion pattern.

Returns:

the instance.

Throws:

ConversionException - if conversion fails.

toComponentString

protected String toComponentString(String className,
                                   Object object,
                                   String pattern)

Returns the string representation of a large object. This is always null as we don't want and can't read the contents of a large object within the conversion context.

Overrides:

toComponentString in class DefaultObjectConverter<Object>

Parameters:

className - the name of the class.

object - the source object.

pattern - the conversion pattern.

Returns:

the string representation.
