Method Detail

getBufferViewModel

BufferViewModel getBufferViewModel()

Returns the BufferViewModel for the data that this accessor provides access to. Typed access to the data is possible by obtaining the AccessorData using getAccessorData().

Returns:

The BufferViewModel

getComponentType

int getComponentType()

Returns the component type of this accessor, as a GL constant. For example, GL_FLOAT or GL_UNSIGNED_SHORT

Returns:

The component type

getComponentDataType

java.lang.Class<?> getComponentDataType()

Returns the data type of the components of this accessor. For example, float.class or short.class.

Returns:

The component data type

getComponentSizeInBytes

int getComponentSizeInBytes()

Returns the size of one component, in bytes

Returns:

The component size, in bytes

getElementSizeInBytes

int getElementSizeInBytes()

Returns the size of one element, in bytes

Returns:

The element size, in bytes

getByteOffset

int getByteOffset()

Returns the byte offset of this accessor referring to its BufferViewModel

Returns:

The byte offset

getCount

int getCount()

Returns the number of elements that this accessor provides access to

Returns:

The number of elements

getElementType

ElementType getElementType()

Returns the ElementType that this accessor provides access to

Returns:

The ElementType

getByteStride

int getByteStride()

Returns the byte stride between the starts of two consecutive elements of this accessor.

Returns:

The byte stride

getAccessorData

AccessorData getAccessorData()

Returns the AccessorData for this accessor. The exact type of the returned AccessorData object will depend on the component data type. It will be AccessorByteData, AccessorShortData, AccessorIntData or AccessorFloatData for a component data type of byte.class, short.class, int.class or float.class, respectively, and can be safely cast to the respective type.

Returns:

The AccessorData

getMin

java.lang.Number[] getMin()

Returns the minimum components of the AccessorData. The returned array will be a clone of the array that is stored internally, and have a length that matches the number of components per element.

Returns:

The minimum components

getMax

java.lang.Number[] getMax()

Returns the maximum components of the AccessorData. The returned array will be a clone of the array that is stored internally, and have a length that matches the number of components per element.

Returns:

The maximum components
