Class JobEntityBatchIndexExtensions

Extensions for scheduling and running IJobEntityBatchWithIndex jobs.

Inheritance

Object

JobEntityBatchIndexExtensions

Namespace: Unity.Entities

Syntax

public static class JobEntityBatchIndexExtensions

Methods

Run<T>(T, EntityQuery)

Runs the job immediately on the current thread.

Declaration

public static void Run<T>(this T jobData, EntityQuery query)
    where T : struct, IJobEntityBatchWithIndex

Parameters

Type	Name	Description
T	jobData	An IJobEntityBatchWithIndex instance.
EntityQuery	query	The query selecting chunks with the necessary components.

Type Parameters

Name	Description
T	The specific IJobEntityBatchWithIndex implementation type.

Remarks

This scheduling variant processes each matching chunk as a single batch. All chunks execute sequentially on the current thread.

ScheduleParallel<T>(T, EntityQuery, JobHandle)

Adds an IJobEntityBatchWithIndex instance to the job scheduler queue for parallel execution.

Declaration

public static JobHandle ScheduleParallel<T>(this T jobData, EntityQuery query, JobHandle dependsOn = default(JobHandle))
    where T : struct, IJobEntityBatchWithIndex

Parameters

Type	Name	Description
T	jobData	An IJobEntityBatchWithIndex instance.
EntityQuery	query	The query selecting chunks with the necessary components.
JobHandle	dependsOn	The handle identifying already scheduled jobs that could constrain this job. A job that writes to a component cannot run in parallel with other jobs that read or write that component. Jobs that only read the same components can run in parallel.

Returns

Type	Description
JobHandle	A handle that combines the current Job with previous dependencies identified by the dependsOn parameter.

Type Parameters

Name	Description
T	The specific IJobEntityBatchWithIndex implementation type.

Remarks

This scheduling variant processes each matching chunk as a single batch. Each chunk can execute in parallel. This scheduling method is equivalent to calling ScheduleParallelBatched<T>(T, EntityQuery, Int32, JobHandle) with the batchesPerChunk parameter set to 1.

ScheduleParallelBatched<T>(T, EntityQuery, Int32, JobHandle)

Adds an IJobEntityBatchWithIndex instance to the job scheduler queue for parallel execution, potentially subdividing chunks into multiple batches.

Declaration

public static JobHandle ScheduleParallelBatched<T>(this T jobData, EntityQuery query, int batchesPerChunk, JobHandle dependsOn = default(JobHandle))
    where T : struct, IJobEntityBatchWithIndex

Parameters

Type	Name	Description
T	jobData	An IJobEntityBatchWithIndex instance.
EntityQuery	query	The query selecting chunks with the necessary components.
Int32	batchesPerChunk	The number of batches to use per chunk. The entities in each chunk matching query are partitioned into this many contiguous batches of approximately equal size. Multiple batches form the same chunk may be processed concurrently.
JobHandle	dependsOn	The handle identifying already scheduled jobs that could constrain this job. A job that writes to a component cannot run in parallel with other jobs that read or write that component. Jobs that only read the same components can run in parallel.

Returns

Type	Description
JobHandle	A handle that combines the current Job with previous dependencies identified by the dependsOn parameter.

Type Parameters

Name	Description
T	The specific IJobEntityBatchWithIndex implementation type.

Remarks

This scheduling variant processes each matching chunk as one or more batches. Each batch, including those from the same chunk, can execute in parallel.

ScheduleSingle<T>(T, EntityQuery, JobHandle)

Adds an IJobEntityBatchWithIndex instance to the job scheduler queue for sequential (non-parallel) execution.

Declaration

public static JobHandle ScheduleSingle<T>(this T jobData, EntityQuery query, JobHandle dependsOn = default(JobHandle))
    where T : struct, IJobEntityBatchWithIndex

Parameters

Type	Name	Description
T	jobData	An IJobEntityBatchWithIndex instance.
EntityQuery	query	The query selecting chunks with the necessary components.
JobHandle	dependsOn	The handle identifying already scheduled jobs that could constrain this job. A job that writes to a component cannot run in parallel with other jobs that read or write that component. Jobs that only read the same components can run in parallel.

Returns

Type	Description
JobHandle	A handle that combines the current Job with previous dependencies identified by the dependsOn parameter.

Type Parameters

Name	Description
T	The specific IJobEntityBatchWithIndex implementation type.

Remarks

This scheduling variant processes each matching chunk as a single batch. All chunks execute sequentially.
