Method Detail

choose

protected abstract LongSignalSource choose()

Returns the chosen the input signal source for the current value. The result may change over time, behaving like a second-order signal source (whose values are signal sources).

getAsLong

public long getAsLong()

Returns the current value of this signal source.

The value may be either computed on demand, or retrieved from storage.

Implementations of this method should have no side effect.

Specified by:

getAsLong in interface LongSignalSource

Specified by:

getAsLong in interface LongSupplier

Returns:

the current value of this signal source

compileDefaultValue

protected Consumer<CompilationContext> compileDefaultValue()

Description copied from class: AbstractSignalSourceChooser

Returns a code generator for loading the default value of the signal type on the operand stack.

Specified by:

compileDefaultValue in class AbstractSignalSourceChooser
