public class Case extends Expression implements org.jvnet.jaxb2_commons.lang.Equals2, org.jvnet.jaxb2_commons.lang.HashCode2, org.jvnet.jaxb2_commons.lang.ToString2
The Case operator allows for multiple conditional expressions to be chained together in a single expression, rather than having to nest multiple If operators. In addition, the comparand operand provides a variant on the case that allows a single value to be compared in each conditional. If a comparand is not provided, the type of each when element of the caseItems within the Case is expected to be boolean. If a comparand is provided, the type of each when element of the caseItems within the Case is expected to be of the same type as the comparand. An else element must always be provided. The static type of the then argument within the first caseItem determines the type of the result, and the then argument of each subsequent caseItem and the else argument must be of that same type.

  • Method Details

    • getComparand

      public Expression getComparand()
      Gets the value of the comparand property.
      Returns:
      possible object is Expression

    • setComparand

      public void setComparand(Expression value)
      Sets the value of the comparand property.
      Parameters:
      value - allowed object is Expression

    • getCaseItem

      public List<CaseItem> getCaseItem()
      Gets the value of the caseItem property.

      This accessor method returns a reference to the live list, not a snapshot. Therefore any modification you make to the returned list will be present inside the JAXB object. This is why there is not a set method for the caseItem property.

      For example, to add a new item, do as follows: 

          getCaseItem().add(newItem);

      Objects of the following type(s) are allowed in the list CaseItem

    • getElse

      public Expression getElse()
      Gets the value of the else property.
      Returns:
      possible object is Expression

    • setElse

      public void setElse(Expression value)
      Sets the value of the else property.
      Parameters:
      value - allowed object is Expression
