Interface AccessorData

All Known Implementing Classes:

AccessorByteData, AccessorFloatData, AccessorIntData, AccessorShortData

public interface AccessorData

Interface for classes that provide typed access to raw accessor data. The exact type of the data (and thus, the implementing class) is defined by the component type:

• For byte.class, the implementation is an AccessorByteData
• For short.class, the implementation is an AccessorShortData
• For int.class, the implementation is an AccessorIntData
• For float.class, the implementation is an AccessorFloatData

Method Summary

Modifier and Type	Method and Description
java.nio.ByteBuffer	createByteBuffer() Creates a new, direct byte buffer (with native byte order) that contains the data for the accessor, in a compact form, without any offset, and without any additional stride (that is, all elements will be tightly packed).
java.lang.Class<?>	getComponentType() Returns the type of the components that this class provides access to.
int	getNumComponentsPerElement() Returns the number of components per element (for example, 3 if the elements are 3D vectors)
int	getNumElements() Returns the number of elements in this data (for example, the number of 3D vectors)
int	getTotalNumComponents() Returns the total number of components (that is, the number of elements multiplied with the number of components per element)

Method Detail

getComponentType

java.lang.Class<?> getComponentType()

Returns the type of the components that this class provides access to. This will usually be a primitive type, like float.class or short.class.

Returns:

The component type

getNumElements

int getNumElements()

Returns the number of elements in this data (for example, the number of 3D vectors)

Returns:

The number of elements

getNumComponentsPerElement

int getNumComponentsPerElement()

Returns the number of components per element (for example, 3 if the elements are 3D vectors)

Returns:

The number of components per element

getTotalNumComponents

int getTotalNumComponents()

Returns the total number of components (that is, the number of elements multiplied with the number of components per element)

Returns:

The total number of components

createByteBuffer

java.nio.ByteBuffer createByteBuffer()

Creates a new, direct byte buffer (with native byte order) that contains the data for the accessor, in a compact form, without any offset, and without any additional stride (that is, all elements will be tightly packed).

Returns:

The byte buffer
