MLGraph

The MLGraph interface represents a compiled computational graph. Once constructed, a compiled graph is immutable and cannot be subsequently modified.

Web IDL

[SecureContext, Exposed=(Window, DedicatedWorker)]
interface MLGraph {
  undefined destroy();
};

Constructor

The MLGraph interface does not have a constructor. Instances are created through other APIs.

Properties

This interface does not contain any properties.

Methods

destroy()

Releases all resources associated with the graph. Once called, the graph is marked as destroyed and cannot be used for further operations.

Syntax

graph.destroy()

Return Value

• undefined

Notes

• The graph is immutable after construction to ensure computational integrity
• All input and output operands must be properly described through their respective descriptors
• The implementation details are managed by the User Agent and are not directly accessible
• After destruction, no further workloads can be enqueued using this graph
• Implementations can free any additional resource allocations associated with this graph once all previously submitted workloads using it are complete

Best Practices

• Always call destroy() when the graph is no longer needed to prevent memory leaks
• Ensure all operations on the graph are complete before calling destroy()
• Do not attempt to use the graph after calling destroy()

Specifications

Security Requirements

The MLGraph interface:

1. Requires a secure context (SecureContext)
2. Is exposed only to Window and DedicatedWorker contexts
3. Cannot be modified after construction to prevent tampering with computational graphs
4. Resource cleanup is performed asynchronously to ensure proper memory management

Browser Compatibility

The Graph interface is under active development and browser support may vary.
