SetIndexBuffer

Assigns a buffer to a specific index.

Syntax

SetIndexBuffer(bufferIndex: number, buffer: TIndexBuffer): void

Parameters

• bufferIndex - A number representing the index to assign the buffer to.

• buffer - A TIndexBuffer object to be assigned to the specified index.

Return Value

This method does not return a value.

Description

The SetIndexBuffer method assigns a buffer to a specific index. This is necessary after creating a buffer with CreateIndexBuffer to specify which index the buffer should be associated with. The index must be less than the number of buffers specified with IndicatorBuffers.

Example

// Specify that the indicator uses 3 buffers
this.api.IndicatorBuffers(3);

// Create buffers
const upperBuffer = this.api.CreateIndexBuffer();
const middleBuffer = this.api.CreateIndexBuffer();
const lowerBuffer = this.api.CreateIndexBuffer();

// Assign buffers to indices
this.api.SetIndexBuffer(0, upperBuffer);
this.api.SetIndexBuffer(1, middleBuffer);
this.api.SetIndexBuffer(2, lowerBuffer);

// Now the buffers can be used to store indicator values
