Detailed Description

Objects of this class are used with ScriptEngine to pass values to the script functions or retrieve their return values.

To pass a value, it's usually enough to just create a ScriptValue from a string or an integer implicitly, using one of the constructors.

When retrieving a value from a script, it is necessary to call one of the GetAsXXX() methods to determine the type of the contained value and get it.

This class has value-like semantics, i.e. objects of this type can be copied and assigned as any primitive value.

Member Function Documentation

◆ GetAsBool()

bool OpalKelly::ScriptValue::GetAsBool ( bool * pb ) const

If the function returns true, pb is filled with the value. Otherwise false is returned and pb is not modified.

◆ GetAsBuffer()

bool OpalKelly::ScriptValue::GetAsBuffer ( Buffer * pbuf ) const

If the function returns true, pbuf is filled with the buffer data. Otherwise false is returned and pbuf is not modified.

◆ GetAsInt()

bool OpalKelly::ScriptValue::GetAsInt ( int * pn ) const

If the function returns true, pn is filled with the value. Otherwise false is returned and pn is not modified.

◆ GetAsString()

bool OpalKelly::ScriptValue::GetAsString ( std::string * ps ) const
