NodeTypeGenerator

public NodeTypeGenerator()

Method Detail

cloneValue

public Object cloneValue(Object valueObject)

Description copied from interface: TypeGenerator

Returns a 'deep' copy of a value.

Parameters:

valueObject - the value

Returns:

a copy of the value

parseString

public Object parseString(String string)
                   throws ParseException

Description copied from interface: TypeGenerator

Returns a value parsed from a String representation.

Parameters:

string - the representation of the value

Returns:

the parsed value

Throws:

ParseException - if the String doesn't represent a value of the type

correctValue

public Object correctValue(Object inValue,
                           Property property)
                    throws WrongFacetException

Description copied from interface: TypeGenerator

Corrects a value of a property so that it fits to the type and facets. It is a precondition that the facets of the property are correct; if necessary, that should be ensured by calling correctFacets(Property). The action taken by the method can afterwards be retrieved by a call to getLastCorrectAction().

Parameters:

inValue - the value

property - the property (to get the facets)

Returns:

the corrected value

Throws:

WrongFacetException - if the facets of the property are erroneous.

correctFacets

public int correctFacets(Property property)

Description copied from interface: TypeGenerator

Checks whether the facets of a property fit to the type and corrects them, if necessary.

Parameters:

property - the property that holds the facets

Returns:

an error code that contains the action taken
