Level1SetSelectedElementsOperator

public Level1SetSelectedElementsOperator(Target target)

Method Detail

ifTrue

public Level1SetSelectedElementsSelectedOperator<I,T> ifTrue(IFunction<? super T,Boolean> eval)

Description copied from interface: SelectableElementsOperator

Selects only those targets for which the specified evaluator returns true. After this method, all the subsequently executed operations will only be executed on the target objects selected here, until an "endIf()" method is called.

Specified by:

ifTrue in interface ILevel1SetSelectedElementsOperator<I,T>

Specified by:

ifTrue in interface SelectableElementsOperator<T>

Parameters:

eval - the evaluator to be used for selecting targets.

Returns:

an operator which will execute all subsequent operations only on the selected target objects.

ifFalse

public Level1SetSelectedElementsSelectedOperator<I,T> ifFalse(IFunction<? super T,Boolean> eval)

Description copied from interface: SelectableElementsOperator

Selects only those targets for which the specified evaluator returns false. After this method, all the subsequently executed operations will only be executed on the target objects selected here, until an "endIf()" method is called.

Specified by:

ifFalse in interface ILevel1SetSelectedElementsOperator<I,T>

Specified by:

ifFalse in interface SelectableElementsOperator<T>

Parameters:

eval - the evaluator to be used for selecting targets.

Returns:

an operator which will execute all subsequent operations only on the selected target objects.

ifNull

public Level1SetSelectedElementsSelectedOperator<I,T> ifNull()

Description copied from interface: SelectableElementsOperator

Selects only those targets which are null. After this method, all the subsequently executed operations will only be executed on the target objects selected here, until an "endIf()" method is called.

Specified by:

ifNull in interface ILevel1SetSelectedElementsOperator<I,T>

Specified by:

ifNull in interface SelectableElementsOperator<T>

Returns:

an operator which will execute all subsequent operations only on the selected target objects.

ifNotNull

public Level1SetSelectedElementsSelectedOperator<I,T> ifNotNull()

Description copied from interface: SelectableElementsOperator

Selects only those targets which are not null. After this method, all the subsequently executed operations will only be executed on the target objects selected here, until an "endIf()" method is called.

Specified by:

ifNotNull in interface ILevel1SetSelectedElementsOperator<I,T>

Specified by:

ifNotNull in interface SelectableElementsOperator<T>

Returns:

an operator which will execute all subsequent operations only on the selected target objects.

ifIndex

public Level1SetSelectedElementsSelectedOperator<I,T> ifIndex(int... indexes)

Description copied from interface: SelectableElementsOperator

Selects only those targets which index in the current level of iteration matches any of the specified indexes. After this method, all the subsequently executed operations will only be executed on the target objects selected here, until an "endIf()" method is called.

Specified by:

ifIndex in interface ILevel1SetSelectedElementsOperator<I,T>

Specified by:

ifIndex in interface SelectableElementsOperator<T>

Parameters:

indexes - the indexes of the target objects which will be selected.

Returns:

an operator which will execute all subsequent operations only on the selected target objects.

ifIndexNot

public Level1SetSelectedElementsSelectedOperator<I,T> ifIndexNot(int... indexes)

Description copied from interface: SelectableElementsOperator

Selects only those targets which index in the current level of iteration does not match any of the specified indexes. After this method, all the subsequently executed operations will only be executed on the target objects selected here, until an "endIf()" method is called.

Specified by:

ifIndexNot in interface ILevel1SetSelectedElementsOperator<I,T>

Specified by:

ifIndexNot in interface SelectableElementsOperator<T>

Parameters:

indexes - the indexes of the target objects which will be selected.

Returns:

an operator which will execute all subsequent operations only on the selected target objects.

endFor

public Level0SetSelectedOperator<I,T> endFor()

Description copied from interface: NavigatingCollectionOperator

Ends the current iteration. After the execution of this method, all subsequent operations will be applied on the iterated collection as a whole instead of in a by-element basis.

Specified by:

endFor in interface ILevel1SetSelectedElementsOperator<I,T>

Specified by:

endFor in interface NavigatingCollectionOperator<T>

Returns:

an operator which will execute all operations on the iterated collection as a whole.

ifNullOrFalse

public Level1SetSelectedElementsSelectedOperator<I,T> ifNullOrFalse(IFunction<? super T,Boolean> eval)

Specified by:

ifNullOrFalse in interface ILevel1SetSelectedElementsOperator<I,T>

ifNotNullAndFalse

public Level1SetSelectedElementsSelectedOperator<I,T> ifNotNullAndFalse(IFunction<? super T,Boolean> eval)

Specified by:

ifNotNullAndFalse in interface ILevel1SetSelectedElementsOperator<I,T>

ifNullOrTrue

public Level1SetSelectedElementsSelectedOperator<I,T> ifNullOrTrue(IFunction<? super T,Boolean> eval)

Specified by:

ifNullOrTrue in interface ILevel1SetSelectedElementsOperator<I,T>

ifNotNullAndTrue

public Level1SetSelectedElementsSelectedOperator<I,T> ifNotNullAndTrue(IFunction<? super T,Boolean> eval)

Specified by:

ifNotNullAndTrue in interface ILevel1SetSelectedElementsOperator<I,T>

exec

public Level1SetSelectedElementsOperator<I,T> exec(IFunction<? super T,? extends T> function)

Description copied from interface: ExecutableSelectedOperator

Executes the specified function on the target object, creating a new operator containing the result of the execution.

This function does not allow the operator target type to change because a selection ("if") has already been done on the target objects, and this would render the operator inconsistent (some objects would belong to a type and others to another type).

Specified by:

exec in interface ILevel1SetSelectedElementsOperator<I,T>

Specified by:

exec in interface ExecutableSelectedOperator<T>

Parameters:

function - the function to be executed

Returns:

an operator on the results of function execution

replaceWith

public Level1SetSelectedElementsOperator<I,T> replaceWith(T replacement)

Description copied from interface: ReplaceableOperator

Replaces the current target object with the specified replacement.

Specified by:

replaceWith in interface ILevel1SetSelectedElementsOperator<I,T>

Specified by:

replaceWith in interface ReplaceableOperator<T>

Parameters:

replacement - the object which will replace the current target object.

Returns:

an operator containing the replacement object as target.

get

public Set<T> get()

Description copied from interface: UniqOpOperator

Returns the target object this operator currently holds.

Specified by:

get in interface UniqOpOperator<I,Set<T>>

Returns:

the target object.
