Detailed Description

template<class T, bool has_ostream = false>
class RTT::types::PrimitiveSequenceTypeInfo< T, has_ostream >

New-style SequenceTypeInfo which offers type info for sequences which can NOT be sent over flow ports.

This has huge code size reduction, while still being able to use these sequences in structs which are sent over flow ports.

Member Function Documentation

AttributeBase * RTT::ValueFactory::buildConstant ( std::string  name,
base::DataSourceBase::shared_ptr  dsb,
int  sizehint 
) const [virtual, inherited]

Build a non modifyable instance of this type.

Parameters:
sizehintFor variable size instances, use it to hint the size of the instance.

Definition at line 14 of file ValueFactory.cpp.

template<class T , bool has_ostream = false>
virtual bool RTT::types::PrimitiveSequenceTypeInfo< T, has_ostream >::composeType ( base::DataSourceBase::shared_ptr  source,
base::DataSourceBase::shared_ptr  target 
) const [inline, virtual]

Compose a type (target) from a DataSourceBase (source) containing its members.

The default behavior tries to assign source to target. If that fails, it tries to decompose target into its members and update the members of target with the contents of source.

The default implementation in TemplateTypeInfo works for most types, but can be overridden in case there are multiple versions/possibilities to make a target from a source. For example, in order to support legacy formats or in order to do the inverse of decomposeType().

Parameters:
sourceA data source of the same type as target OR a PropertyBag that contains the parts of target to be refreshed.
targetA data source of the same type as this TypeInfo object which contains the data to be updated from source.
Returns:
true if source could be updated, false otherwise.
See also:
types::propertyDecomposition and types::typeDecomposition for the inverse function, decomposing a type into datasources and hierarchical properties.
decomposeType to do the inverse operation.

Implements RTT::types::CompositionFactory.

Definition at line 52 of file PrimitiveSequenceTypeInfo.hpp.

Specialize this function to return an alternate type which represents this one in a compatible way.

For example, a short converts to an long or an enum to an int or a string.

Returns:
null if this type is not convertible to anything else.
Deprecated:
by decomposeType. We want to rename convertType to decomposeType. This function is left here for transitional purposes.

Definition at line 6 of file CompositionFactory.cpp.

template<class T , bool has_ostream = false>
virtual base::DataSourceBase::shared_ptr RTT::types::PrimitiveSequenceTypeInfo< T, has_ostream >::decomposeType ( base::DataSourceBase::shared_ptr  source) const [inline, virtual]

Specialize this function to return an alternate type which represents this one in a compatible way.

For example, a short converts to an long or an enum to an int or a string. If your return a datasource containing a property bag, then this function should do the inverse of composeType: the returned property bag contains all parts of the current type (source) which can be modified and merged back into this type with composeType. Mathematically: composeType( decomposeType( A ), B); assert( A == B );

Returns:
null in order to indicate that decomposition through getMember() may be tried. You may return source itself in order to prevent any further decomposition of your type (using getMember(), which is used as fall-back by the rest of the software. For example, to avoid that a string is decomposed into a sequence of chars, or to avoid that a primitive type like 'int' is further queried.

Reimplemented from RTT::types::CompositionFactory.

Definition at line 61 of file PrimitiveSequenceTypeInfo.hpp.

virtual bool RTT::types::MemberFactory::getMember ( internal::Reference ref,
base::DataSourceBase::shared_ptr  item,
const std::string &  name 
) const [virtual, inherited]

Stores a reference to a member of a struct identified by its name.

This method does not allocate memory when item is assignable..

Parameters:
refThe reference object in which to store the reference.
itemThe item of which to return a reference to a member. It must be assignable, otherwise, a reference to a copy of item will be returned. This copy will allocate memory.
nameThe name of a member within item.
Returns:
false if no such member exists, true if ref got filled in otherwise.
TypeInfo* RTT::types::PrimitiveTypeInfo< T, use_ostream >::getTypeInfoObject ( ) const [inline, virtual, inherited]

Returns the TypeInfo object of this type, or null if none exists yet.

Returns:
All generators should return here TypeInfoRepository::Instance()->getTypeInfo<T>();

Implements RTT::types::TypeInfoGenerator.

Definition at line 83 of file PrimitiveTypeInfo.hpp.

virtual const std::string& RTT::types::PrimitiveTypeInfo< T, use_ostream >::getTypeName ( ) const [inline, virtual, inherited]

Return the type name for which this generator generates type info features.

This name will be aliased by the TypeInfo object.

Implements RTT::types::TypeInfoGenerator.
