Uses of StateStore in com.wualabs.qtsurfer.engine.core.state

Classes in com.wualabs.qtsurfer.engine.core.state that implement StateStore

Modifier and Type	Class	Description
class	MemoryStateStore	KV on memory State store implementation

Methods in com.wualabs.qtsurfer.engine.core.state that return StateStore

Modifier and Type	Method	Description
StateStore	StateStoreProvider.getStateStore(Instrument instrument)	Returns the state store for the given instrument.

Uses of StateStore in com.wualabs.qtsurfer.engine.indicators.helpers

Methods in com.wualabs.qtsurfer.engine.indicators.helpers that return StateStore

Modifier and Type	Method	Description
StateStore	OnChangeRTIndicator.getStateStore()	Resolves this indicator's state store: the externally supplied one if OnChangeRTIndicator.setStateStoreSupplier(Supplier) was called, otherwise a private in-memory store created on demand.

Methods in com.wualabs.qtsurfer.engine.indicators.helpers with parameters of type StateStore

Modifier and Type	Method	Description
protected void	OnChangeRTIndicator.notifyOnChange(@NonNull StateStore store, double prevValue, double newValue)	Broadcasts with a store the caller already resolved, so an event that had to write state itself does not resolve twice.
void	OnChangeRTIndicator.OnChangeListener.onChange(StateStore store, double prev, double actual)	Fired on a value change with the resolved StateStore directly — never a factory to unwrap.

Method parameters in com.wualabs.qtsurfer.engine.indicators.helpers with type arguments of type StateStore

Modifier and Type	Method	Description
void	OnChangeRTIndicator.setStateStoreSupplier(@NonNull Supplier<StateStore> stateStoreSupplier)	Routes this indicator's state at an externally owned store, typically the one shared by every indicator of an instrument.

Uses of StateStore in com.wualabs.qtsurfer.engine.indicators.helpers.group

Methods in com.wualabs.qtsurfer.engine.indicators.helpers.group that return StateStore

Modifier and Type	Method	Description
StateStore	InstrumentGroupRTIndicator.getStateStore()	Returns this group's state store — the single store every window listener of this instrument shares — either the injected one or an in-memory store created on first access.

Method parameters in com.wualabs.qtsurfer.engine.indicators.helpers.group with type arguments of type StateStore

Modifier and Type	Method	Description
InstrumentGroupRTIndicator	InstrumentGroupRTIndicator.stateStoreSupplier(@NonNull Supplier<StateStore> stateStoreSupplier)	Replaces the store this group hands to its windows.
WindowTimeRTIndicatorBuilder	WindowTimeRTIndicatorBuilder.stateStoreSupplier(Supplier<StateStore> stateStoreSupplier)

default Optional<StateStore>	Strategy.getStateStore(@NonNull Instrument instrument)

Uses of StateStore in com.wualabs.qtsurfer.engine.strategy.execution

Methods in com.wualabs.qtsurfer.engine.strategy.execution that return types with arguments of type StateStore

Modifier and Type	Method	Description
