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.

Build a modifyable instance of this type.
- Parameters
-
sizehint For variable size instances, use it to hint the size of the instance.

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
-
source A data source of the same type as target OR a PropertyBag that contains the parts of target to be refreshed. target A 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.

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.

inlinevirtual |
Returns a member of a given data source struct identified by its name.
- Parameters
-
item The item of which to return a reference to a member name The name of a member within item. Is a name of a member in case of a struct or an index number in case of a sequence.
- Returns
- null if no such member exists, an assignable datasource referencing that member otherwise.

inlinevirtual |
Returns a member of a given data source identified by a data source id. This will be an int (for indexing) or a string (for the member name).
- Warning
- Currently this only works for a SequenceTypeInfo-like object. We don't implement this for StructTypeInfo-like objects, since that would be a very expensive implementation (memory wise).
- Parameters
-
item The item of which to return a member id Or a string data source containing the name of a member if item is a struct, Or an unsigned int data source containing the index of an element if item is a sequence

Returns the list of struct member names of this type. In case this type is not a struct, returns an empty list.

Installs the type info object in the global data source type info handler and adds any additional features to the type info object. This method will be called by the TypeInfoRepository, in order to register this type's factories into the TypeInfo object.
- Returns
- true if this object may be deleted, false if not.
- Postcondition
- When true is returned, this instance is still valid and the caller (TypeInfoRepository) will delete it. When false is returned, the validity is undefined and the instance will not be used anymore by the caller.

Tries to resize a data source in case it's a resizable sequence.
- Returns
- true if the resizing could be done, false otherwise.
