Buffer

Methods

copyFromArrayView

DOC_TBA DOC_TBA: arrayView

Parameters:

Name	Type	Argument	Default	Description
offsetInBytes	Number	<optional>	0	DOC_TBA

Throws:

• DeveloperError : This buffer is not large enough.
• DeveloperError : This buffer was destroyed, i.e., destroy() was called.

destroy

Destroys the WebGL resources held by this object. Destroying an object allows for deterministic release of WebGL resources, instead of relying on the garbage collector to destroy this object.

Once an object is destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception. Therefore, assign the return value (undefined) to the object as done in the example.

Throws:

DeveloperError : This buffer was destroyed, i.e., destroy() was called.

Returns:

Example

buffer = buffer && buffer.destroy();

• Buffer#isDestroyed
• glDeleteBuffers

getSizeInBytes

DOC_TBA

Throws:

DeveloperError : This buffer was destroyed, i.e., destroy() was called.

Returns:

Number DOC_TBA

getUsage

DOC_TBA

Throws:

DeveloperError : This buffer was destroyed, i.e., destroy() was called.

Returns:

GLenum DOC_TBA

getVertexArrayDestroyable

DOC_TBA

isDestroyed

Returns true if this object was destroyed; otherwise, false.

If this object was destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception.

Returns:

Boolean True if this object was destroyed; otherwise, false.
