Redeclares com.badlogic.gdx.utils.Disposable.dispose.

Disposes this IndexDatat and all its associated OpenGL resources.

getBuffer back to summary

getBuffer	back to summary
public ShortBuffer getBuffer() Deprecated use `getBuffer(boolean)` instead Returns the underlying ShortBuffer. If you modify the buffer contents they will be uploaded on the next call to `bind()`. If you need immediate uploading use `setIndices(short[], int, int)`. Returns:ShortBuffer the underlying short buffer. Annotations @Deprecated

public ShortBuffer getBuffer()

Deprecated

use getBuffer(boolean) instead

Returns the underlying ShortBuffer. If you modify the buffer contents they will be uploaded on the next call to bind(). If you need immediate uploading use setIndices(short[], int, int).

Returns:ShortBuffer

the underlying short buffer.

@Deprecated

getBuffer back to summary

getBuffer	back to summary
public ShortBuffer getBuffer(boolean forWriting) Returns the underlying ShortBuffer for reading or writing. Parameters forWriting:boolean when true, the underlying buffer will be uploaded on the next call to `bind()`. If you need immediate uploading use `setIndices(short[], int, int)`. Returns:ShortBuffer the underlying short buffer.

public ShortBuffer getBuffer(boolean forWriting)

Returns the underlying ShortBuffer for reading or writing.

Parameters

forWriting:boolean: when true, the underlying buffer will be uploaded on the next call to bind(). If you need immediate uploading use setIndices(short[], int, int).

Returns:ShortBuffer

the underlying short buffer.

getNumIndices	back to summary
public int getNumIndices() Returns:int the number of indices currently stored in this buffer

getNumMaxIndices	back to summary
public int getNumMaxIndices() Returns:int the maximum number of indices this IndexBufferObject can store.

invalidate	back to summary
public void invalidate() Invalidates the IndexBufferObject so a new OpenGL buffer handle is created. Use this in case of a context loss.

setIndices back to summary

setIndices	back to summary
public void setIndices(short[] indices, int offset, int count) Sets the indices of this IndexBufferObject, discarding the old indices. The count must equal the number of indices to be copied to this IndexBufferObject. This can be called in between calls to `bind()` and `unbind()`. The index data will be updated instantly. Parameters indices:short[] the index data offset:int the offset to start copying the data from count:int the number of shorts to copy

public void setIndices(short[] indices, int offset, int count)

Sets the indices of this IndexBufferObject, discarding the old indices. The count must equal the number of indices to be copied to this IndexBufferObject.

This can be called in between calls to bind() and unbind(). The index data will be updated instantly.

Parameters

indices:short[]: the index data
offset:int: the offset to start copying the data from
count:int: the number of shorts to copy

setIndices back to summary

setIndices	back to summary
public void setIndices(ShortBuffer indices) Copies the specified indices to the indices of this IndexBufferObject, discarding the old indices. Copying start at the current `ShortBuffer#position()` of the specified buffer and copied the `ShortBuffer#remaining()` amount of indices. This can be called in between calls to `bind()` and `unbind()`. The index data will be updated instantly. Parameters indices:ShortBuffer the index data to copy

public void setIndices(ShortBuffer indices)

Copies the specified indices to the indices of this IndexBufferObject, discarding the old indices. Copying start at the current ShortBuffer#position() of the specified buffer and copied the ShortBuffer#remaining() amount of indices. This can be called in between calls to bind() and unbind(). The index data will be updated instantly.

Parameters

indices:ShortBuffer: the index data to copy

unbind	back to summary
public void unbind() Unbinds this IndexBufferObject.

updateIndices	back to summary
public void updateIndices(int targetOffset, short[] indices, int offset, int count) Update (a portion of) the indices. Parameters targetOffset:int offset in indices buffer indices:short[] the index data offset:int the offset to start copying the data from count:int the number of shorts to copy

updateIndices

back to summary

public void updateIndices(int targetOffset, short[] indices, int offset, int count)

Update (a portion of) the indices.

Parameters

targetOffset:int: offset in indices buffer
indices:short[]: the index data
offset:int: the offset to start copying the data from
count:int: the number of shorts to copy

public Interface IndexData
