                      String className,
                      DXEnvironment env)

Initializes a new execution with the specified execution ID and environment.

Parameters:

className - class name that should prefix the ID

DXExecution

protected DXExecution(String dxId,
                      String className,
                      DXEnvironment env,
                      com.fasterxml.jackson.databind.JsonNode cachedDescribe)

Initializes a new execution with the specified execution ID, environment, and cached describe data.

Parameters:

className - class name that should prefix the ID

Method Detail

getInstance

public static DXExecution getInstance(String executionId)

Returns a DXExecution corresponding to an existing execution with the specified ID.

Parameters:

executionId - DNAnexus execution id

Returns:

a DXExecution handle to the specified object

getInstanceWithEnvironment

public static DXExecution getInstanceWithEnvironment(String executionId,
                                                     DXEnvironment env)

Returns a DXExecution corresponding to an existing execution with the specified ID, using the specified environment.

Parameters:

executionId - DNAnexus execution id

env - environment to use to make subsequent API requests

Returns:

a DXExecution handle to the specified object

checkCachedDescribeAvailable

protected void checkCachedDescribeAvailable()
                                     throws IllegalStateException

Verifies that this object carries cached describe data.

Throws:

IllegalStateException - if cachedDescribe is not set

describe

public abstract DXExecution.Describe describe()

Obtains metadata about the execution.

Returns:

a Describe containing execution metadata

getCachedDescribe

public abstract DXExecution.Describe getCachedDescribe()

Returns metadata about the data object, like describe(), but without making an API call.

This cached describe info is only available if this object appears in the result of a DXSearch.findExecutions() call that specified DXSearch.FindExecutionsRequestBuilder.includeDescribeOutput(). The describe info that is returned reflects the state of the object at the time that the search was performed.

Returns:

a Describe containing the execution's metadata

Throws:

IllegalStateException - if no cached describe info is available

getOutput

public abstract <T> T getOutput(Class<T> outputClass)
                         throws IllegalStateException

Returns the output of the execution, deserialized to the specified class.

Parameters:

outputClass - class to deserialize to

Returns:

execution output

Throws:

IllegalStateException - if the execution is not in the DONE state.

terminate

public abstract void terminate()

Terminates the execution.

waitUntilDone

public abstract DXExecution waitUntilDone()
                                   throws IllegalStateException

Waits until the execution has successfully completed and is in the DONE state.

Returns:

the same DXExecution object

Throws:

IllegalStateException - if the execution reaches the FAILED or TERMINATED state.
