not the ActionListener instance. There is nothing special about the use ofthisin a lambda expression. The scope of the lambda expression is nested inside theinitmethod, and this has the same meaning anywhere in that method.
propagates errors, meaning that if the input contains an error (e.g., #VALUE!, #REF!), the function will return the same error. 6.1 Troubleshooting the error value When you encounter an error value in a cell a warning symbol appears, displayed in the image above. Press with mouse on ...
In the example above, the _ points to the lambda function. For more details about the usage of this special character in Python, check out The Meaning of Underscores in Python.Another pattern used in other languages like JavaScript is to immediately execute a Python lambda function. This is ...
A characteristic feature of Russell’s approach is that no meaning is assigned to the expression ‘the F’ standing alone, but only in the context of complete sentences in which it occurs. ‘The F is G’ means ‘There is exactly one F and it is G’. Thus the complex term ‘The F’...
This has a problem for us – the tryAdvance function always returns true meaning we can never stop. We could implement our own Spliterator where our tryAdvance checks for a stop condition. We can’t simply extend InfiniteSupplyingSpliterator and override the tryAdvance method since it’s an ...
* Indicates that this collector is concurrent, meaning that * the result container can support the accumulator function being * called concurrently with the same result container from multiple * threads. * * If a {@code CONCURRENT} collector is not also {@code UNORDERED}, * then it should...
The call to returns the identity function, which returns its own input, meaning that each string is its own key (line 21). The second argument is a downstream reducer that operates on the stream of strings that map to the same key (line 22). Of course, the stream of strings that map...
nobody could have added atransform(java.util.function. Function)method to their own classes. But in Java 12, it was too late. Someone somewhere could have definedtransform(java.util.function.Function)in their class, with a different meaning. Admittedly, it is unlikely that this ever happened,...
radius -> {System.out.println(radius);returnMath.PI* radius * radius; } The first example’s expression-based lambda body doesn’t have to be placed between braces. The second example converts the expression-based body to a statement-based body, in whichreturnmust be specified to return th...
