LiteralAccessor, PropertyAccessor

All Known Implementing Classes:

public interface IntLiteralAccessor

extends LiteralAccessor

Encapsulates the standard methods of modifying a property on a DAML object, where the value of the property is an RDF literal (as opposed to another DAML value, see PropertyAccessor, and the literal is known to encapsulate an integer value.

Throws:

{@link - java.lang.RuntimeException} if the property is not defined or cannot be interpreted as an integer.

addInt

public void addInt(int value)

Add a value to the encapsulated property.

Parameters:

value - The value to be added, as an int.

removeInt

public void removeInt(int value)

Remove an integer value from the encapsulated property.

Parameters:

value - The value to be removed, as an int.

hasIntValue

public boolean hasIntValue(int value)

Answer true if the encapsulated property has the given value as one of its values.

Parameters:

value - An int value to test for

Returns:
