// /TOP_1/STRUCT_BLOCK_2/STRUCT_QUARTET_1/DET_SI1-T1

// STRUCTURE & DETECTOR NAME FORMATTING
// ====================================
// -- STRUCTURES --
// The default names for structures are taken from the node name by stripping off
// the "STRUCT_" prefix. It is assumed that the remaining string is of the form
// "[structure type]_[structure number]"
// (the structure number is always taken after the last occurence of '_' in the
// node name). This is the name that will be used by default for the structure.
// However, this format can be change by calling method
// SetStructureNameFormat("[structure type]", "[format]")
// where format can contain any of the following tokens:
// $type$ - will be replaced by the structure type name
// $type%[fmt]$ - will be replaced by the structure type name using given format
// $number$ - will be replaced by the structure number
// $number%[fmt]$ - will be replaced by the structure number using given format
//
// Example: to change the name of the block in the previous example to "B-02",
// SetStructureNameFormat("BLOCK", "$type%.1s$-$number%02d$")
//
// -- DETECTORS --
// The default base names for detectors are taken from the node name by stripping off
// the "DET_" prefix. In order to ensure that all detectors have unique names,
// by default we prefix the names of the parent structures to the basename in
// order to generate the full name of the detector:
// [struc1-name]_[struc2-name]_..._[detector-basename]
// However, this format can be changed by calling method
// SetDetectorNameFormat("[format]")
// where format can contain any of the following tokens:
// $det:name$ - will be replaced by the detector basename
// $struc:[type]:name$ - will be replaced by the name of the parent structure of given type
// $struc:[type]:type$ - will be replaced by the type of the parent structure of given type
// $struc:[type]:number$ - will be replaced by the number of the parent structure of given type
// plus additional formatting information as for SetStructureNameFormat (see above).
//
// Example: to change the name of the "SI1-T1" detector in the previous example to
// "SI1-T1-Q1-B2":
// SetDetectorNameFormat("$det:name$-Q$struc:QUARTET:number$-B$struc:BLOCK:number$")
// Or if you also change the format of the structure names:
// SetStructureNameFormat("BLOCK", "$type%.1s$$number$")
// SetStructureNameFormat("QUARTET", "$type%.1s$$number$")
// SetDetectorNameFormat("$det:name$-$struc:QUARTET:name$-$struc:BLOCK:name$")
