Method Summary

ILevel2MapSelectedEntriesKeyOperator<I,K,V>	endIf() Ends the selection currently active for this level.
ILevel2MapSelectedEntriesKeySelectedOperator<I,K,V>	exec(IFunction<? super K,? extends K> function) Executes the specified function on the target object, creating a new operator containing the result of the execution.
ILevel2MapSelectedEntriesKeySelectedOperator<I,K,V>	replaceWith(K replacement) Replaces the current target object with the specified replacement.

Method Detail

endIf

ILevel2MapSelectedEntriesKeyOperator<I,K,V> endIf()

Description copied from interface: SelectedMapEntryComponentOperator

Ends the selection currently active for this level.

Specified by:

endIf in interface SelectedMapEntryComponentOperator<K>

Returns:

an operator which will execute all subsequent operations on all the target objects instead of only on the previously selected ones.

replaceWith

ILevel2MapSelectedEntriesKeySelectedOperator<I,K,V> replaceWith(K replacement)

Description copied from interface: ReplaceableOperator

Replaces the current target object with the specified replacement.

Specified by:

replaceWith in interface ReplaceableOperator<K>

Parameters:

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

Returns:

an operator containing the replacement object as target.

exec

ILevel2MapSelectedEntriesKeySelectedOperator<I,K,V> exec(IFunction<? super K,? extends K> 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 ExecutableSelectedOperator<K>

Parameters:

function - the function to be executed

Returns:

an operator on the results of function execution
