public class TLcdEarthObjectMappedIndexedVertexArray
extends TLcdEarthIndexedVertexArray

An indexed vertex array that has an object mapped to each element of the vertex array. If a vertex array contains the visual representation of more than one domain object, for instance, then this class can be used to map parts of the vertex array back to their originating domain object. This in turn makes it possible to visualize this vertex array in parts rather than as a whole, and to apply different styling to different parts of the array.

Constructor Details

TLcdEarthObjectMappedIndexedVertexArray

public TLcdEarthObjectMappedIndexedVertexArray()

Creates a new TLcdEarthObjectMappedIndexedVertexArray. Object mapping information must be set before this vertex array can be used.

See Also:

• setObjects(Object[], int[])

Method Details

setObjects

public void setObjects(Object[] aObjects,
 int[] aOffsets)

Sets the list of objects whose data is in this vertex array and the offsets at which these objects can be found in the vertex array. The two arrays must have equal lengths. aOffsets[i] should point to the start of aObjects[i] in TLcdEarthIndexedVertexArray.getIndices(). The objects are assumed to be continuous in TLcdEarthIndexedVertexArray.getIndices(), i.e. there should be no holes or unmapped indices in between objects. Hence, the number of indices corresponding to an object is implied by the offset of the next object. The last object is assumed to range from its start offset to the end of TLcdEarthIndexedVertexArray.getIndices(). The first object's offset is expected to be 0.

All elements in TLcdEarthIndexedVertexArray.getIndices() must be mapped to exactly 1 object (i.e. the first/last end index should exactly be the index of the first/last element of TLcdEarthIndexedVertexArray.getIndices()) and the end index should always be greater than or equal to the start index.

Parameters:

aObjects - the list of objects

aOffsets - the list of offsets for the given objects

• TLcdEarthIndexedVertexArray.getIndices()

getMappedObject

public Object getMappedObject(int aElementIndex)

Returns the object that is mapped to the element at the given index in TLcdEarthIndexedVertexArray.getIndices().

Parameters:

aElementIndex - A valid element index

Returns:

The mapped object

getObjectCount

public int getObjectCount()

Returns the total number of objects that have some data in this vertex array.

Returns:

The number of mapped objects.

getObject

public Object getObject(int aObjectIndex)

Returns the object at the given index.

Parameters:

aObjectIndex - An index in [0,getObjectCount()[.

Returns:

The object at the given index.

getObjectStartOffset

public int getObjectStartOffset(int aObjectIndex)

Returns the start offset in TLcdEarthIndexedVertexArray.getIndices() of the object at the given index. This offset is obtained from the array supplied by setObjects(Object[], int[]).

Parameters:

aObjectIndex - An index in [0,getObjectCount()[.

Returns:

The start offset, which points to an element of TLcdEarthIndexedVertexArray.getIndices()

getObjectEndOffset

public int getObjectEndOffset(int aObjectIndex)

Returns the end offset in TLcdEarthIndexedVertexArray.getIndices() of the object at the given index. This offset is the start offset of the next object minus one, or the last element of TLcdEarthIndexedVertexArray.getIndices() in the case of the last object.

Parameters:

aObjectIndex - An index in [0,getObjectCount()[.

Returns:

The end offset, which points to an element of TLcdEarthIndexedVertexArray.getIndices()
