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

Disposes this VertexData and all its associated OpenGL resources.

getAttributes	back to summary
public VertexAttributes getAttributes() Returns:VertexAttributes the `VertexAttributes` as specified during construction.

getBuffer back to summary

getBuffer	back to summary
public FloatBuffer getBuffer() Deprecated use `getBuffer(boolean)` instead. Returns the underlying FloatBuffer and marks it as dirty, causing the buffer contents to be uploaded on the next call to bind. If you need immediate uploading use `setVertices(float[], int, int)`; Any modifications made to the Buffer after the call to bind will not automatically be uploaded. Returns:FloatBuffer the underlying FloatBuffer holding the vertex data. Annotations @Deprecated

public FloatBuffer getBuffer()

Deprecated

use getBuffer(boolean) instead.

Returns the underlying FloatBuffer and marks it as dirty, causing the buffer contents to be uploaded on the next call to bind. If you need immediate uploading use setVertices(float[], int, int); Any modifications made to the Buffer *after* the call to bind will not automatically be uploaded.

Returns:FloatBuffer

the underlying FloatBuffer holding the vertex data.

Annotations

@Deprecated

getBuffer back to summary

getBuffer	back to summary
public FloatBuffer getBuffer(boolean forWriting) Returns the underlying FloatBuffer 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 `setVertices(float[], int, int)`. Returns:FloatBuffer the underlying FloatBuffer holding the vertex data.

public FloatBuffer getBuffer(boolean forWriting)

Returns the underlying FloatBuffer 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 setVertices(float[], int, int).

Returns:FloatBuffer

the underlying FloatBuffer holding the vertex data.

getNumMaxVertices	back to summary
public int getNumMaxVertices() Returns:int the number of vertices this VertedData can store

getNumVertices	back to summary
public int getNumVertices() Returns:int the number of vertices this VertexData stores

invalidate	back to summary
public void invalidate() Invalidates the VertexData if applicable. Use this in case of a context loss.

setVertices back to summary

setVertices	back to summary
public void setVertices(float[] vertices, int offset, int count) Sets the vertices of this VertexData, discarding the old vertex data. The count must equal the number of floats per vertex times the number of vertices to be copied to this VertexData. The order of the vertex attributes must be the same as specified at construction time via `VertexAttributes`. This can be called in between calls to bind and unbind. The vertex data will be updated instantly. Parameters vertices:float[] the vertex data offset:int the offset to start copying the data from count:int the number of floats to copy
