Private Member Functions
int	value (lua_State *L)
	Returns the scalar, vector or matrix value at the specified index.
int	valueStr (lua_State *L)
	Returns the value at the given index converted to a string (even for multivalued values).

Additional Inherited Members
Protected Attributes inherited from GmLuaAccessorBase< GmDiscontinuityAccessor >
GmDiscontinuityAccessor *	_ac
	The wrapped value accessor object.
bool	_owner
	Do we own the accessor?
Protected Attributes inherited from GmLuaObject
const GmLogCategory &	_logger
	A logger used by the proxy when needed.
QAtomicInteger< int >	_refCount
	Lua objects are reference counted to enable sharing them among different states. This is needed to allow for passing objects as parameters in a parallel call. The garbage collection method releases memory only for the last reference.

Detailed Description

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

Member Function Documentation

fillMetatable()

void GmLuaDiscontinuityAccessor::fillMetatable ( lua_State * L, int index )

virtual

Prepares the object metatable for calling methods.

Reimplemented from GmLuaAccessorIndex< GmDiscontinuityAccessor, const GmDiscontinuity * >.

getClassMetatableID()

virtual void * GmLuaDiscontinuityAccessor::getClassMetatableID ( )

inlinevirtual

Returns an unique identifier to identify an user object as a GmValueAccessor object.

Implements LuaProxy::Base.

parseIndex()

const GmDiscontinuity * GmLuaDiscontinuityAccessor::parseIndex ( lua_State * L, int stackPos, QString fname ) const

protectedvirtual

Parses and checks an index based on a cell object.

Implements GmLuaAccessorIndex< GmDiscontinuityAccessor, const GmDiscontinuity * >.

typeName()

virtual const char * GmLuaDiscontinuityAccessor::typeName ( ) const

inlinevirtual

Returns the object type as will be stored in the object metatable.

Implements GmLuaObject.

value()

int GmLuaDiscontinuityAccessor::value ( lua_State * L )

private

Returns the scalar, vector or matrix value at the specified index.

Stack parameters: index

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

valueStr()

int GmLuaDiscontinuityAccessor::valueStr ( lua_State * L )

private

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

Stack parameters: index, optional options table.

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')
