InnerTaskOptions<T extends Struct> mixin

Parent class for building block options classes which are later grouped together to comprise all relevant options for a specific MediaPipe task.

The native implementation suggests two methods each extending class should implement: assignToStruct and freeStructFields. Both methods are passed a struct created and managed elsewhere, and these methods either copy local values into native memory (assignToStruct) or deallocate any native memory that a naive calloc.free() from the parent options class would miss.

Properties

hashCode → int
The hash code for this object.
no setterinherited
props → List<Object?>
The list of properties that will be used to determine whether two instances are equal.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stringify → bool?
If set to true, the toString method will be overridden to output this instance's props.
no setterinherited

Methods

assignToStruct(T struct) → void
Assigns all values to an existing struct. This method should be implemented by all InnerTaskOptions types to hydrate a struct, but not for the creation of that struct. Allocation and management of the actual structs are handled by TaskOptions.copyToNative on the wrapping options object.
freeStructFields(T struct) → void
Deallocates any memory on the struct that would be missed simply by calling calloc.free(struct), which the parent who called this method will do after this method completes.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
