Method Detail

execAsMap

<X,Y> ExecutableMapOperator<X,Y> execAsMap(IFunction<? super Map<K,V>,? extends Map<X,Y>> function)

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

This function must be able to take as input an object of the current operator's target type, and will return an object of a different type but same structure, which will be from then on the new operator's target type.

Type Parameters:

X - the type of the resulting keys

Y - the type of the resulting values

Parameters:

function - the function to be executed

Returns:

an operator on the results of function execution

exec

<X> Operator exec(IFunction<? super Map<K,V>,X> function)

Executes the specified function on the target object, creating a new generic operator containing the result of the execution and setting the new operator type to the one specified.

Type Parameters:

X - the type of the result object

Parameters:

function - the function to be executed

Returns:

an operator on the results of function execution

execIfNotNullAsMap

ExecutableMapOperator<K,V> execIfNotNullAsMap(IFunction<? super Map<K,V>,? extends Map<? extends K,? extends V>> function)

Executes a function in a way equivalent to execAsMap(IFunction) but only on selected elements, leaving all other elements untouched.

Parameters:

function - the function to be executed on the selected elements

Returns:

an operator on the results of function execution

execIfNullAsMap

ExecutableMapOperator<K,V> execIfNullAsMap(IFunction<? super Map<K,V>,? extends Map<? extends K,? extends V>> function)

Executes a function in a way equivalent to execAsMap(IFunction) but only on selected elements, leaving all other elements untouched.

Parameters:

function - the function to be executed on the selected elements

Returns:

an operator on the results of function execution

execIfTrueAsMap

ExecutableMapOperator<K,V> execIfTrueAsMap(IFunction<? super Map<K,V>,Boolean> eval,

Executes a function in a way equivalent to execAsMap(IFunction) but only on selected elements, leaving all other elements untouched.

Parameters:

eval - the evaluation function used to select elements
