public interface ExecutableMapEntrySelectedOperator<K,V>

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

Method Summary

ExecutableMapEntrySelectedOperator<K,V>

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

Method Detail

execAsMapEntry

ExecutableMapEntrySelectedOperator<K,V> execAsMapEntry(IFunction<? super Map.Entry<K,V>,? extends Map.Entry<? extends K,? extends V>> function)

Executes the specified function on the target mape entry, creating a new map entry 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
