Method new()

Initializes a CSWConstraint object to be used to constrain CSW operations.

Usage

CSWConstraint$new(cqlText = NULL, filter = NULL, serviceVersion = "2.0.2")

Arguments

cqlText

cqlText, object of class character

filter

filter, object extending OGCFilter

serviceVersion

CSW service version. Default is "2.0.2"

---

Method setServiceVersion()

Set service version. This methods ensures that underlying filter property is properly set with the right OGC filter version.

Usage

CSWConstraint$setServiceVersion(serviceVersion)

Arguments

serviceVersion

service version

---

Method clone()

The objects of this class are cloneable with this method.

Usage

CSWConstraint$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Examples

  filter <- OGCFilter$new( PropertyIsEqualTo$new("apiso:Identifier", "12345") )
  cons <- CSWConstraint$new(filter = filter)
  cons_xml <- cons$encode() #how it looks like in XML
