Method Detail

convertToComplexType

public java.awt.Image convertToComplexType(java.io.InputStream convertFrom)
                                    throws org.apache.commons.beanutils.ConversionException

Description copied from interface: BidirectionalConverter

Converts an object of type S to an object of type C. The given object we are converting from must contain a valid representation of the object or else an IllegalArgumentException will be thrown.

Specified by:

convertToComplexType in interface BidirectionalConverter<java.io.InputStream,java.awt.Image>

Parameters:

convertFrom - The object to convert.

Returns:

The complex type representation of the object.

Throws:

org.apache.commons.beanutils.ConversionException - Thrown if the object could not be converted to a complex type even though the simple type is a correct representation.

convertToSimpleType

public java.io.InputStream convertToSimpleType(java.awt.Image convertFrom,
                                               java.lang.Object... additionalInfo)

Description copied from interface: BidirectionalConverter

This method converts an object of type C to an object of type S.

Specified by:

convertToSimpleType in interface BidirectionalConverter<java.io.InputStream,java.awt.Image>

Parameters:

convertFrom - The object to convert.

additionalInfo - Some types of object require some kind of additional information to be properly persisted which is passed through here. One specific place is when converting Cubes to get their data source. There is probably a better way of doing this.

Returns:

The simple type representation of the object.
