Members

<static, constant> BYTE :Enumeration

8-bit signed byte enumeration corresponding to gl.BYTE and the type of an element in Int8Array.

Default Value:

• 0x1400

<static, constant> DOUBLE :Enumeration

64-bit floating-point enumeration corresponding to gl.DOUBLE (in Desktop OpenGL; this is not supported in WebGL, and is emulated in Cesium via GeometryPipeline.encodeAttribute) and the type of an element in Float64Array.

Default Value:

• 0x140A

<static, constant> FLOAT :Enumeration

32-bit floating-point enumeration corresponding to FLOAT and the type of an element in Float32Array.

Default Value:

• 0x1406

<static, constant> SHORT :Enumeration

16-bit signed short enumeration corresponding to SHORT and the type of an element in Int16Array.

Default Value:

• 0x1402

<static, constant> UNSIGNED_BYTE :Enumeration

8-bit unsigned byte enumeration corresponding to UNSIGNED_BYTE and the type of an element in Uint8Array.

Default Value:

• 0x1401

<static, constant> UNSIGNED_INT :Enumeration

32-bit unsigned int enumeration corresponding to UNSIGNED_INT and the type of an element in Uint32Array.

<static, constant> UNSIGNED_SHORT :Enumeration

16-bit unsigned short enumeration corresponding to UNSIGNED_SHORT and the type of an element in Uint16Array.

Default Value:

• 0x1403

Methods

<static> validate

Validates that the provided component datatype is a valid ComponentDatatype

Parameters:

Name	Type	Description
componentDatatype	ComponentDatatype	The component datatype to validate.

Returns:

Boolean true if the provided component datatype is a valid enumeration value; otherwise, false.

Example

if (!ComponentDatatype.validate(componentDatatype)) {
  throw new DeveloperError('componentDatatype must be a valid enumeration value.');
}
