Create()

static TPtr Create ( const std::string &  _filename, const std::string &  _name  )

inlinestatic

a class method that creates a plugin from a file name.

It locates the shared library and loads it dynamically.

Parameters

[in]	_filename	the path to the shared library.
[in]	_name	short name of the plugin

Returns

Shared Pointer to this class type

References PluginT< T >::filename, gzerr, and SingletonT< SystemPaths >::Instance().

GetFilename()

std::string GetFilename ( ) const

inline

Get the name of the handler.

References PluginT< T >::filename.

GetHandle()

std::string GetHandle ( ) const

inline

Get the short name of the handler.

References PluginT< T >::handleName.

GetType()

PluginType GetType ( ) const

inline

Returns the type of the plugin.

Returns

type of the plugin

References PluginT< T >::type.

LoadParam() [1/2]

void LoadParam ( const sdf::ElementPtr &  _sdf, const std::string &  _name, V &  _target, V  _defaultValue = V()  ) const

inlineprotected

Load parameter value from _sdf and store it to the given reference, using the supplied default value if the element in _sdf is not found.

A message is written using gzmsg reporting whether the default value was used or not.

Parameters

[in]	_sdf	The SDF element of the plugin.
[in]	_name	Name of a tag inside the SDF.
[out]	_target	The reference to store the param value to.
[in]	_defaultValue	The default value.

References gzmsg, and PluginT< T >::handleName.

LoadParam() [2/2]

void LoadParam ( sdf::ElementPtr &  _sdf, const std::string &  _name, std::string &  _target, const char *  _defaultValue  ) const

inlineprotected

Load parameter value from _sdf and store it to the given reference, using the supplied default value if the element in _sdf is not found.

A message is written using gzmsg reporting whether the default value was used or not. String specialization to allow accepting const char* values for std::string parameters.

Parameters

[in]	_sdf	The SDF element of the plugin.
[in]	_name	Name of a tag inside the SDF.
[out]	_target	The reference to store the param value to.
[in]	_defaultValue	The default value.
