    where T : struct, IBufferElementData

Parameters

Type	Name	Description
Int32	sortKey	A unique index for each set of commands added to this EntityCommandBuffer across all parallel jobs writing commands to this buffer. The entityInQueryIndex argument provided by Entities is an appropriate value to use for this parameter. In an IJobEntityBatch pass the 'batchIndex' value from Execute(ArchetypeChunk, Int32).
Entity	e	The entity to which the dynamic buffer belongs.
T	element	The new element to add to the DynamicBuffer<T> component.

Type Parameters

Name	Description
T	The IBufferElementData type stored by the DynamicBuffer<T>.

Remarks

Behavior at Playback: Will throw an error if this entity is destroyed before playback, if this entity is still deferred, or if the entity doesn't have a DynamicBuffer<T> component storing elements of type T.

Exceptions

Type	Condition
InvalidOperationException	Thrown if the entity does not have a DynamicBuffer<T> component storing elements of type T at the time the entity command buffer executes this append-to-buffer command.
NullReferenceException	Throws if an Allocator was not passed in when the EntityCommandBuffer was created.
