Class OperationFactory

java.lang.Object

com.sun.corba.se.spi.orb.OperationFactory

public abstract class OperationFactory
extends Object

This is a static factory class for commonly used operations for property parsing. The following operations are supported:

• maskErrorAction( Operation op ) executes op and returns the result. If op throws an exception, the result is null.
• indexAction( int arg ) returns the [arg] element of value, which must be an Object[]
• identityAction() return the value
• booleanAction() return a Boolean representing true or false values of the String value
• integerAction() returns an Integer for the String value, which must be a decimal integer
• stringAction() returns the String value
• classAction() returns a class for the String value, as loaded by the ORB classloader
• setFlagAction() always return Boolean.TRUE
• URLAction() returns a java.net.URL for the String value, which must be a valid URL
• integerRangeAction( int min, int max ) returns an Integer for the String value, which must be a decimal integer in the range min to max inclusive
• listAction( String sep, Operation ) tokenizes the String value with sep as separator, then applies the Operation to each token, and returns an array of the result
• sequenceAction( String, Operation[] ) tokenizes the String value with sep as separator, then applies each Operation in the Operation array to successive tokens, and returns an array of the results
• compose( Operation op1, Operation op2 ) is the operation that applies op2 to the result of applying op1 to the value
• mapAction( Operation ) applies the Operation to each element of an array of objects, and returns an array of the results
• mapSequenceAction( Operation[] ) applies the corresponding element of the Operation array to an element of the Object[] value, and returns an array of the results
• convertIntegerToShort coerces an Integer into a Short.

Other operations can be directly defined, and combined using these basic operations.
