ILS_GLOBAL_FUNCTION

Category

Dynamic view-related macros

Description

These macros declare global functions as being accessible at runtime, so that they can be used in dynamic view type specifications.

They MUST NOT be enclosed between the following pairs of macros:

ILS_OBJECT_BEGIN/ILS_OBJECT_END

ILS_ENTITY_BEGIN/ILS_ENTITY_END

ILS_MVVIEW_BEGIN/ILS_MVVIEW_END

param2Type,param3Type,param4Type)

ILS_GLOBAL_FUNCTION5(resType,funNm,param1Type,

ILS_GLOBAL_FUNCTION6(resType,funNm,param1Type,param2Type,

param3Type,param4Type,param5Type,param6Type)

Arguments

These macros take the following arguments, in this order:

the type of the value returned by the function,

the function name

the types of the function parameters.

All the global runtime functions must have a unique name. The result and the parameters of a global function can be of the following types:

char

char*

IlsString

IlsBoolean

short

int

long

float

double

any type that derives from IlsMvUserType.

When a runtime-accessible global function is called from a component, the result is not sent back to this component, because the callback mechanism is completely asynchronous. However, to allow for the requirements of type macro expansion, such a function cannot have a result of type void.
