CommandBuffer class

CommandBuffer in this library is used as a tape to record actions for the native backend to execute. Commands are stored as a continuous stream of raw bytes. Each command constists of two parts:

OpCode (4 bytes): storing which method should be executed on the backend

Arguments: providing additional arguments for the operation. Example:

 [OpCode (4 bytes)] [Len A (2 bytes)] [Text A] [Len B (2 bytes)] [Text B] [Len Out (2 bytes)] [Text Out]

Usually CommandBuffers do not need to be filled manually but are filled by providing them to GPUTensor- operations as arguments.

Constructors

CommandBuffer()

Properties

hashCode → int

The hash code for this object.

no setter, inherited

offset ↔ int

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

bytes() → Uint8List

Returns a copy of the active portion of the buffer. Primarily used to decode the buffer into a Uint8List to run CommandBuffers on the GPU:

clear() → void

sets the storage offset to 0

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

patchInt(int reservedOffset, int value) → void

Overwrites a 4-byte int previously written at reservedOffset in place.

putBool(bool value) → void

Inserts a bool into the buffer

putFloat(double value) → void

Inserts a float into the buffer

putInt(int value) → void

Inserts an integer into the buffer

putString(String text) → void

Inserts a given String into the buffer vie encoding over uft-8

reserveInt() → int

Reserves 4 bytes for a value that isn't known yet and writes a 0 placeholder there. Returns the offset so the value can be overwritten later without re-recording the tape.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
