CudaContext (nd4j-jcublas-7.5 0.4-rc3.7 API)

java.lang.Object
- org.nd4j.linalg.jcublas.context.CudaContext

All Implemented Interfaces:

AutoCloseable
```
public class CudaContext
extends Object
implements AutoCloseable
```
A higher level class for handling the different primitives around the cuda apis This being: streams (both old and new) as well as the cublas handles.

Modifier and Type	Method and Description
`void`	`associateHandle()` Associates the handle on this context to the given stream
`void`	`close()`
`void`	`destroy()` Destroys the context and associated resources
`void`	`destroy(CublasPointer resultPointer, boolean freeIfNotEqual)` Destroys the context and associated resources
`void`	`finishBlasOperation()` Finishes a blas operation and destroys this context
`static CudaContext`	`getBlasContext()` Sets up a context with an old stream and a blas handle
`CublasPointer`	`getResultPointer()`
`void`	`initHandle()` Initializes a handle and associates with the given stream.
`void`	`initOldStream()` Initializes the old stream
`void`	`initStream()` Initializes the stream
`void`	`syncDevice()`
`void`	`syncHandle()` Synchrnonizes on the old stream since the given handle will be associated with the stream for this context
