GenericConstBuffer
Engine/source/gfx/genericConstBuffer.h
This class manages shader constant data in a system memory buffer.
Set shader constant values
Actually set shader constant values
Parameters:
| name | Name of the constant, this should be a name contained in the array returned in getShaderConstDesc, if an invalid name is used, its ignored, but it's not an error. |

getDirtyBuffer(U32 * start, U32 * size)
Gets the dirty buffer range and clears the dirty state at the same time.
Gets the entire buffer ignoring dirty range.
bool
isDirty()
Returns true if the buffer has been modified since the last call to getDirtyBuffer or setDirty.
bool
isEqual(const GenericConstBuffer * buffer)
Returns true if have the same layout and hold the same data as the input buffer.
Returns our layout object.
internalSet(const GenericConstBufferLayout::ParamDesc & pd, const GFXShaderConstType constType, const U32 size, const void * data)
Called by the inlined set functions above to do the real dirty work of copying the data to the right location within the buffer.
The buffer layout.
The byte offset to the start of the dirty range within the buffer or U32_MAX if the buffer is not dirty.
Public Functions
Detailed Description
This class manages shader constant data in a system memory buffer.
It is used by device specific classes for batching together many constant changes which are then copied to the device thru a single API call.

getDirtyBuffer(U32 * start, U32 * size)
Gets the dirty buffer range and clears the dirty state at the same time.
getEntireBuffer()
Gets the entire buffer ignoring dirty range.
setDirty(bool dirty)
Sets the entire buffer as dirty or clears the dirty state.
isDirty()
Returns true if the buffer has been modified since the last call to getDirtyBuffer or setDirty.
The buffer is not dirty on initial creation.
isEqual(const GenericConstBuffer * buffer)
Returns true if have the same layout and hold the same data as the input buffer.
getLayout()

getBuffer()
Returns a pointer to the raw buffer.
internalSet(const GenericConstBufferLayout::ParamDesc & pd, const GFXShaderConstType constType, const U32 size, const void * data)
Called by the inlined set functions above to do the real dirty work of copying the data to the right location within the buffer.
GenericConstBufferLayout * mLayout
The buffer layout.
U8 * mBuffer
The pointer to the contant store or NULL if the layout is empty.
U32 mDirtyStart
The byte offset to the start of the dirty range within the buffer or U32_MAX if the buffer is not dirty.
U32 mDirtyEnd
The btye offset to the end of the dirty range within the buffer or 0 if the buffer is not dirty.
