Detailed Description

template<typename PropertyType>
class armarx::Property< PropertyType >

Provides access to Ice properties with extended capabilities.

The Property template class provides access to Ice config properties and command line options. Its main capability is to map a string value on any type that is required and put constrains on the value as well as on the property itself at the same time. For instance you can specify that a certain property is required for the component to proceed or a property may require a specific value syntax or even numeric bounds which may not be exceeded. These features and few more are supported by the Property combined with the PropertyDefinition.

Member Function Documentation

getValue()

template<typename PropertyType>

PropertyType getValue

(

)

Returns the property value set in a config file or passed as a command-line option.

If property is not set, the default value is returned unless the property is required. In the latter case an exception is thrown indicating that the required property is not set.

Returns

Property value of the type PropertyType

Exceptions

armarx::exceptions::local::ValueRangeExceededException
armarx::exceptions::local::InvalidPropertyValueException
