Method Details

buildPrototype

public ThreadPoolConfig buildPrototype()

Create an instance of the prototype. Calling this method may update this builder from providers and decorators, so repeated calls may have side effects.

Specified by:

buildPrototype in interface Prototype.Builder<ThreadPoolConfig.Builder, ThreadPoolConfig>

Returns:

an instance of the setup object created from this builder

build

public ThreadPoolSupplier build()

Create an instance from this builder. Calling this method may update this builder from providers and decorators, so repeated calls may have side effects.

Specified by:

build in interface Builder<ThreadPoolConfig.Builder, ThreadPoolSupplier>

Returns:

instance of the built type
