Constructor Details

BaseContextImpl

protected BaseContextImpl(ExecutionManager executionManager,
 DurableConfig durableConfig,
 com.amazonaws.services.lambda.runtime.Context lambdaContext,
 String contextId,
 String contextName,
 ThreadType threadType)

Creates a new BaseContext instance.

Parameters:

executionManager - the execution manager for thread coordination and state management

durableConfig - the durable execution configuration

lambdaContext - the AWS Lambda runtime context

contextId - the context ID, null for root context, set for child contexts

contextName - the human-readable name for this context

threadType - the type of thread this context runs on

Method Details

getLambdaContext

public com.amazonaws.services.lambda.runtime.Context getLambdaContext()

Returns the AWS Lambda runtime context.

Specified by:

getLambdaContext in interface BaseContext

Returns:

the Lambda context

getExecutionArn

public String getExecutionArn()

Returns metadata about the current durable execution.

The execution context provides information that remains constant throughout the execution lifecycle, such as the durable execution ARN. This is useful for tracking execution progress, correlating logs, and referencing this execution in external systems.

Specified by:

getExecutionArn in interface BaseContext

Returns:

the execution context

getDurableConfig

public DurableConfig getDurableConfig()

Returns the configuration for durable execution behavior.

Specified by:

getDurableConfig in interface BaseContext

Returns:

the durable configuration

getContextId

public String getContextId()

Gets the context ID for this context. Null for root context, set for child contexts.

Specified by:

getContextId in interface BaseContext

getContextName

public String getContextName()

Gets the context name for this context. Null for root context.

Specified by:

getContextName in interface BaseContext

getExecutionManager

public ExecutionManager getExecutionManager()

isReplaying

public boolean isReplaying()

Returns whether this context is currently in replay mode.

Specified by:

isReplaying in interface BaseContext

setExecutionMode

public void setExecutionMode()

Transitions this context from replay to execution mode. Called when the first un-cached operation is encountered.
