Interface GLArrayData

public interface GLArrayData

The total number of bytes hold by the referenced buffer is: getComponentSize()* getComponentNumber() * getElementNumber()

Method Summary

void	destroy(GL gl)
Buffer	getBuffer() The Buffer holding the data, may be null if a GPU buffer without client bound data
int	getComponentCount() The number of components per element
int	getComponentSizeInBytes() The component's size in bytes
int	getComponentType() The component's GL data type, ie.
int	getElementCount() The current number of used elements. In case the buffer's position is 0 (sealed, flipped), it's based on it's limit instead of it's position.
int	getIndex() The index of the predefined array index, see list below, or -1 in case of a shader attribute array.
int	getLocation() Returns the shader attribute location for this name, -1 if not yet determined
String	getName() The name of the reflecting shader array attribute.
boolean	getNormalized() True, if GL shall normalize fixed point data while converting them into float
int	getSizeInBytes() The currently used size in bytes. In case the buffer's position is 0 (sealed, flipped), it's based on it's limit instead of it's position.
int	getStride()
int	getVBOName() The VBO name or 0 if not a VBO
long	getVBOOffset() The VBO buffer offset or 0 if not a VBO
int	getVBOTarget() The VBO target or 0 if not a VBO
int	getVBOUsage() The VBO usage or 0 if not a VBO
boolean	isVBO() Determines whether the data is server side (VBO) and enabled, or a client side array (false).
boolean	isVertexAttribute() Returns true if this data set is intended for a GLSL vertex shader attribute, otherwise false, ie intended for fixed function vertex pointer
void	setLocation(int v) Sets the determined location of the shader attribute This is usually done within ShaderState.
void	setName(String newName) Set a new name for this array.
String	toString()

Method Detail

isVertexAttribute

boolean isVertexAttribute()

Returns true if this data set is intended for a GLSL vertex shader attribute, otherwise false, ie intended for fixed function vertex pointer

getIndex

int getIndex()

The index of the predefined array index, see list below, or -1 in case of a shader attribute array.

See Also:

GLPointerFunc.GL_VERTEX_ARRAY, GLPointerFunc.GL_NORMAL_ARRAY, GLPointerFunc.GL_COLOR_ARRAY, GLPointerFunc.GL_TEXTURE_COORD_ARRAY

getName

String getName()

The name of the reflecting shader array attribute.

setName

void setName(String newName)

Set a new name for this array.

getLocation

int getLocation()

Returns the shader attribute location for this name, -1 if not yet determined

setLocation

void setLocation(int v)

Sets the determined location of the shader attribute This is usually done within ShaderState.

com.jogamp.opengl.util.glsl.ShaderState#vertexAttribPointer(GL2ES2, GLArrayData)

isVBO

boolean isVBO()

Determines whether the data is server side (VBO) and enabled, or a client side array (false).

getVBOOffset

long getVBOOffset()

The VBO buffer offset or 0 if not a VBO

getVBOName

int getVBOName()

The VBO name or 0 if not a VBO

getVBOUsage

int getVBOUsage()

The VBO usage or 0 if not a VBO

Returns:

0 if not a GPU buffer, otherwise GL2ES2.GL_STREAM_DRAW, GL.GL_STATIC_DRAW or GL.GL_DYNAMIC_DRAW

getVBOTarget

int getVBOTarget()

The VBO target or 0 if not a VBO

Returns:

0 if not a GPU buffer, otherwise GL.GL_ARRAY_BUFFER or GL.GL_ELEMENT_ARRAY_BUFFER

getBuffer

Buffer getBuffer()

The Buffer holding the data, may be null if a GPU buffer without client bound data

getComponentCount

int getComponentCount()

The number of components per element

getComponentType

int getComponentType()

The component's GL data type, ie. GL_FLOAT

getComponentSizeInBytes

int getComponentSizeInBytes()

The component's size in bytes

getElementCount

int getElementCount()

The current number of used elements.
In case the buffer's position is 0 (sealed, flipped), it's based on it's limit instead of it's position.

getSizeInBytes

int getSizeInBytes()

The currently used size in bytes.
In case the buffer's position is 0 (sealed, flipped), it's based on it's limit instead of it's position.

getNormalized

boolean getNormalized()

True, if GL shall normalize fixed point data while converting them into float

getStride

int getStride()

Returns:

the byte offset between consecutive components

toString

String toString()

Overrides:

toString in class Object

destroy

void destroy(GL gl)
