Method Detail

build

T build()

apply

default B apply(UnaryOperator<B> function)

A convenience operator that takes something that will mutate the builder in some way and allows inclusion of it in chaining operations. For example instead of:

 Builder builder = ClassBeingBuilt.builder();
 builder = Util.addSomeDetailToTheBuilder(builder);
 ClassBeingBuilt clz = builder.build();
 

This can be done in a statement:

 ClassBeingBuilt = ClassBeingBuilt.builder().apply(Util::addSomeDetailToTheBuilder).build();
 

Parameters:

function - the function that mutates and then returns the builder

Returns:

B the mutated builder instance
