DirectiveCriteria[]	getDirectiveCriteria(DirectiveCriteriaKey key) Get a DirectiveCriteria array given the input DirectiveCriteriaKey.

Method Detail

addOperation

public void addOperation(Directive directive)
                  throws WTException

This method defines a pattern for Directive implementation classes. It makes calls to validateOperation(Directive directive) and processOperation(Directive directive) which is implemented in the concrete Directive implementations and is responsible for merging the operations.

Supported API: false

Specified by:

addOperation in interface Directive

Parameters:

directive - Represents the database operation or set of database operations that are being added to this Directive object.

Throws:

WTException

validateOperation

public void validateOperation(Directive directive)
                       throws WTException

Validates that the Directive being added is of the same type as the Directive it is being added to. If they are not of the same type an Exception is thrown. If for some reason Directive objects of different types can be added to one another, the concrete implementations of those Directive types would need to override this mehod and do validation appropriate to their implementation.

Supported API: false

Parameters:

directive - Represents the database operation or set of database operations that are being added to this Directive object.

Throws:

WTException

processOperation

public void processOperation(Directive directive)
                      throws WTException

This method is responsible for doing the real work of merging the necessary operation information from the Directive being added, to the Directive it is being added to.

Supported API: false

Parameters:

directive - Represents the database operation or set of database operations that are being added to this Directive object.

Throws:

WTException

getDirectiveCriteria

public DirectiveCriteria[] getDirectiveCriteria(DirectiveCriteriaKey key)

Get a DirectiveCriteria array given the input DirectiveCriteriaKey.

Supported API: false

Specified by:

getDirectiveCriteria in interface Directive

Parameters:

key -

Returns:

DirectiveCriteria[]

putDirectiveCriteria

public void putDirectiveCriteria(DirectiveCriteria directiveCriteria,
                                 DirectiveCriteriaKey key)

This method checks for an existing DirectiveCriteria object that is the same is the input object. If it finds one it appends any QueryKey objects are already stored in the existing DirectiveCriteria object otherwise it is added to the list of DirectiveCriteria objects associated to the input Directive.

Supported API: false

Specified by:

putDirectiveCriteria in interface Directive

Parameters:

directiveCriteria -

key -

getTypes

public String[] getTypes()

Determines what types are internally stored in the DirectiveCriteria objects for this Directive, and returns an array of String objects representing the list of fully qualified class names for those types.

Supported API: false

Specified by:

getTypes in interface Directive

Returns:

String[]

getResult

public DirectiveResult getResult()

Gets the object for the association that plays role: result.

Supported API: false

Specified by:

getResult in interface Directive

Returns:

DirectiveResult

setResult

public void setResult(DirectiveResult a_Result)
               throws WTPropertyVetoException

Sets the object for the association that plays role: result.

Supported API: false

Specified by:

setResult in interface Directive

Parameters:

a_Result -

Throws:

WTPropertyVetoException

resultValidate

private void resultValidate(DirectiveResult a_Result)
                     throws WTPropertyVetoException

Parameters:

a_Result -

Throws:

WTPropertyVetoException

toString

public String toString()
