---

Method addDerivationUnitTerm()

Adds a derivation unit term, made of a uom reference, and an exponent which can be negative/positive but not equal to zero.

Usage

GMLDerivedUnit$addDerivationUnitTerm(uom, exponent)

Arguments

uom

unit of measure reference

exponent

exponent

Returns

TRUE if added, FALSE otherwise

---

Method delDerivationUnitTerm()

Deletes a derivation unit term.

Usage

GMLDerivedUnit$delDerivationUnitTerm(uom, exponent)

Arguments

uom

unit of measure reference

exponent

exponent

Returns

TRUE if deleted, FALSE otherwise

---

Method clone()

The objects of this class are cloneable with this method.

Usage

GMLDerivedUnit$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Examples

  gml <- GMLDerivedUnit$new()
  gml$setDescriptionReference("someref")
  gml$setIdentifier("identifier", "codespace")
  gml$addName("name2", "codespace")
#> [1] TRUE
  gml$setQuantityTypeReference("someref")
  gml$setCatalogSymbol("symbol")
  gml$addDerivationUnitTerm("uomId", 2L)
#> [1] TRUE
