question: checks if the name of the torename identifier already exists in the given configuration implementation as local name for a component . if the newname already exists the refactoringstatus is marked as erroneous and context information is added . if the newname doesnt exist the refactoringstatus is not modified.if the oldname doesnt exist this method doesnt have any effect . concode_field_sep ASTUtil astUtil concode_field_sep void handleCollisionsInConfigurationImplementationScope concode_elem_sep void newInterfaceNameWithLocalInterfaceName concode_elem_sep void newNameWithLocalInterfaceName concode_elem_sep Identifier existsLocalInterfaceName concode_elem_sep void handleCollisions4NewInterfaceNameWithConfigurationLocalName concode_elem_sep void addInfo concode_elem_sep void handleCollisions4NewFileName concode_elem_sep void handleCollisions4NewComponentNameWithConfigurationLocalName concode_elem_sep Identifier existsLocalComponentName concode_elem_sep void handleCollisions4Scope
