cee::vtfx::Block
-
class Block : public RefCountedObject
Abstract base class for all VTFx blocks.
Only for internal use in the VTFx component.
All blocks must have an id that is equal to or greater than zero. The block id must be unique within each block class and the database they have been added to. Blocks use their id to reference each other, e.g. an element block references its associated node blocks using block ids.
Usually one creates a block in a local scope and also writes the block to a database (or a case) within that scope. Databases and cases do not take the ownership of blocks, so it is up the user to clean up block instances properly.
Subclassed by ElementBlock, GeometryBlock, GeometryInfoBlock, NodeBlock, ResultBlock, ResultValuesBlock, SetBlock, StateInfoBlock, TransformationResultBlock, TransformationResultValuesBlock
Public Types
-
enum BlockType
Global block type constants used by the VTFx component.
Normally users do not need these, except for some methods of TransformationResultValuesBlock
Values:
-
enumerator NODES
Node block.
-
enumerator ELEMENTS
Elements block.
-
enumerator GEOMETRY
Geometry block.
-
enumerator GEOMETRYINFO
Geometry info block.
-
enumerator RESULT
Result block.
-
enumerator RESULTVALUES
Result values block (scalars, vectors, displacements)
-
enumerator TRANSFORMATIONRESULT
Transformation result block.
-
enumerator TRANSFORMATIONRESULTVALUES
Transformation result values block (matrices)
-
enumerator STATEINFO
State info block.
-
enumerator SET
Element set block.
-
enumerator ILLEGAL
-
enumerator NODES
Public Functions
-
Block(int blockId)
Constructs an empty block with given block id.
-
virtual ~Block()
-
int blockId() const
Returns the block id.
-
virtual bool checkValidity() const
Does a weak check for valid block contents just before the block is being written.
This method checks if the user forgot to set pre-defined values such as ids, block mappings, names, etc. Note: Only a weak check is possible since a block might appear valid, but still can cause problems in the context of a complete VTFx file.
Returns true if no invalid settings were found in block.
