public interface ExecutableMapSelectedOperator<K,V>

This interface contains methods for executing functions on operators with map target objects on which a selection ("if") has already been done.

1.0

Method Summary

ExecutableMapSelectedOperator<K,V>

execAsMap(IFunction<? super Map<K,V>,? extends Map<? extends K,? extends V>> function) Executes the specified function on the target object, creating a new map operator containing the result of the execution.

Method Detail

execAsMap

ExecutableMapSelectedOperator<K,V> execAsMap(IFunction<? super Map<K,V>,? extends Map<? extends K,? extends V>> function)

Executes the specified function on the target object, creating a new map 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).

Parameters:

function - the function to be executed

Returns:

an operator on the results of function execution
