Detailed Description

A proxy class to export GmBoundaryConditionAccessor methods to the Lua environment.

Member Function Documentation

value()

int GmLuaBoundaryConditionAccessor::value ( lua_State *  L )

private

Returns the scalar, vector or matrix value at the specified index, calculated at the specified coordinate, if available and the value is a function that requires an element coordinate.

Stack parameters: index (bcIndex + listIndex), optional coordinate (either a table or an object).

IMPORTANT: Following Lua spirit, the boundary condition indices are ONE based (and not zero based as in C)

The coordinate value is optional. If present it can be a lua table or a vector object.

The returned value can be a single number for scalar values or a vector/matrix object for other value types.

valueStr()

int GmLuaBoundaryConditionAccessor::valueStr ( lua_State *  L )

private

Returns the value at the given index converted to a string (even for multivalued values).

Stack parameters: index(bcIndex + listIndex), optional coord (either a table or an object), optional options table. IMPORTANT: Following Lua spirit, the boundary condition indices ares ONE based (and not zero based as in C)

The options table can have the following optional fields: evalFunctions – Should we evaluate functions or do we print its name? Default = false defNil – Should we print default values as 'nil'? Default = false format – Printf like format string (ex: '12.4f')
