Class CatalystInstanceImpl

java.lang.Object

com.facebook.react.cxxbridge.CatalystInstanceImpl

All Implemented Interfaces:

CatalystInstance, MemoryPressureListener

public class CatalystInstanceImpl
extends java.lang.Object
implements CatalystInstance

This provides an implementation of the public CatalystInstance instance. It is public because it is built by XReactInstanceManager which is in a different package.

Method Detail

runJSBundle

public void runJSBundle()

Specified by:

runJSBundle in interface CatalystInstance

getSourceURL

@Nullable
public java.lang.String getSourceURL()

Description copied from interface: CatalystInstance

Return the source URL of the JS Bundle that was run, or null if no JS bundle has been run yet.

Specified by:

getSourceURL in interface CatalystInstance

callFunction

public void callFunction(ExecutorToken executorToken,
                         java.lang.String module,
                         java.lang.String method,
                         NativeArray arguments)

Specified by:

callFunction in interface CatalystInstance

invokeCallback

public void invokeCallback(ExecutorToken executorToken,
                           int callbackID,
                           NativeArray arguments)

Specified by:

invokeCallback in interface CatalystInstance

destroy

public void destroy()

Destroys this catalyst instance, waiting for any other threads in ReactQueueConfiguration (besides the UI thread) to finish running. Must be called from the UI thread so that we can fully shut down other threads.

Specified by:

destroy in interface CatalystInstance

isDestroyed

public boolean isDestroyed()

Specified by:

isDestroyed in interface CatalystInstance

initialize

public void initialize()

Initialize all the native modules

Specified by:

initialize in interface CatalystInstance

getReactQueueConfiguration

public ReactQueueConfiguration getReactQueueConfiguration()

Specified by:

getReactQueueConfiguration in interface CatalystInstance

getJSModule

public <T extends JavaScriptModule> T getJSModule(java.lang.Class<T> jsInterface)

Specified by:

getJSModule in interface CatalystInstance

getJSModule

public <T extends JavaScriptModule> T getJSModule(ExecutorToken executorToken,
                                                  java.lang.Class<T> jsInterface)

Specified by:

getJSModule in interface CatalystInstance

hasNativeModule

public <T extends NativeModule> boolean hasNativeModule(java.lang.Class<T> nativeModuleInterface)

Specified by:

hasNativeModule in interface CatalystInstance

getNativeModule

public <T extends NativeModule> T getNativeModule(java.lang.Class<T> nativeModuleInterface)

Specified by:

getNativeModule in interface CatalystInstance

getNativeModules

public java.util.Collection<NativeModule> getNativeModules()

Specified by:

getNativeModules in interface CatalystInstance

handleMemoryPressure

public void handleMemoryPressure(MemoryPressure level)

Description copied from interface: MemoryPressureListener

Called when the system generates a memory warning.

Specified by:

handleMemoryPressure in interface MemoryPressureListener

addBridgeIdleDebugListener

public void addBridgeIdleDebugListener(NotThreadSafeBridgeIdleDebugListener listener)

Adds a idle listener for this Catalyst instance. The listener will receive notifications whenever the bridge transitions from idle to busy and vice-versa, where the busy state is defined as there being some non-zero number of calls to JS that haven't resolved via a onBatchComplete call. The listener should be purely passive and not affect application logic.

Specified by:

addBridgeIdleDebugListener in interface CatalystInstance

removeBridgeIdleDebugListener

public void removeBridgeIdleDebugListener(NotThreadSafeBridgeIdleDebugListener listener)

Removes a NotThreadSafeBridgeIdleDebugListener previously added with addBridgeIdleDebugListener(com.facebook.react.bridge.NotThreadSafeBridgeIdleDebugListener)

Specified by:

removeBridgeIdleDebugListener in interface CatalystInstance

setGlobalVariable

public void setGlobalVariable(java.lang.String propName,
                              java.lang.String jsonValue)

Specified by:

setGlobalVariable in interface CatalystInstance

getJavaScriptContext

public long getJavaScriptContext()

Description copied from interface: CatalystInstance

Get the C pointer (as a long) to the JavaScriptCore context associated with this instance.

Specified by:

getJavaScriptContext in interface CatalystInstance

supportsProfiling

public boolean supportsProfiling()

Specified by:

supportsProfiling in interface CatalystInstance

startProfiler

public void startProfiler(java.lang.String title)

Specified by:

startProfiler in interface CatalystInstance

stopProfiler

public void stopProfiler(java.lang.String title,
                         java.lang.String filename)

Specified by:

stopProfiler in interface CatalystInstance
