class | ::TestPointExecutable |
Object that encapsulates compiled AX code which can be executed on a collection of VDB Point Data grids. Executables are created by the compiler and hold the final immutable JIT compiled function and context.
The PointExecutable is returned from the ax::Compiler when compiling AX code for point execution. The class represents a typical AX executable object; immutable except for execution settings and implements 'execute' functions which can be called multiple times for arbitrary sets of inputs. The intended usage of these executables is to configure their runtime arguments and then call PointExecutable::execute with your VDBs. For example:
The setCreateMissing is initialised with specific configurable settings:
using Ptr = std::shared_ptr<PointExecutable> |
~PointExecutable | ( | ) |
PointExecutable | ( | const PointExecutable & | other | ) |
Copy constructor. Shares the LLVM constructs but deep copies the settings. Multiple copies of an executor can be used at the same time safely.
void execute | ( | points::PointDataGrid & | grid | ) | const |
Run this point executable binary on a target PointDataGrid.
This method reads from the stored settings on the executable to determine certain behaviour and runs the JIT compiled function across every valid point. Point attributes may be created, deleted collapsed or expanded, and points themselves may be added, deleted or moved.
This method is thread safe; it can be run concurrently from the same PointExecutable instance on different inputs.

const AttributeBindings& getAttributeBindings | ( | ) | const |
bool getCreateMissing | ( | ) | const |
size_t getGrainSize | ( | ) | const |
const std::string& getGroupExecution | ( | ) | const |
void setAttributeBindings | ( | const AttributeBindings & | bindings | ) |
Set attribute bindings.
bindings | A map of attribute bindings to expected names on the geometry to be executed over. By default the AX attributes will be bound to point attributes of the same name. Supplying bindings for a subset of the attributes will leave the others unchanged. AX attributes can only bind to a single point attribute and vice versa. However, in a single set call these can be swapped e.g. a -> b and b -> a. When bindings are overriden through subsequent calls to this function, any dangling point attributes will be automatically bound by name. To reset these bindings call get function and create a target set of bindings for each attribute of name -> name. |
void setCreateMissing | ( | const bool | flag | ) |
Set the behaviour when missing point attributes are accessed. Default behaviour is true, which creates them with default initial values. If false, a missing attribute runtime error will be thrown on missing accesses.
flag | Enables or disables the creation of missing attributes |
void setGrainSize | ( | const size_t | grain | ) |
Set the threading grain size. Default is 1. A value of 0 has the effect of disabling multi-threading.
grain | The grain size |
void setGroupExecution | ( | const std::string & | name | ) |
Set a specific point group to execute over. The default is none, which corresponds to all points. Note that this can also be compiled into the AX function using the ingroup("mygroup") method.
name | The name of the group to execute over |
