Detailed Description

Class for struct parser.

Class used to parse a struct (type) definition (class TypeCodeStruct in implementation)

XML schema is

  <xsd:complexType name="StructType">
    <xsd:sequence>
      <xsd:element name="member" type="MemberType" minOccurs="0" maxOccurs="unbounded"/>
    </xsd:sequence>
    <xsd:attribute name="name" type="xsd:string" use="required"/>
    <xsd:attribute name="id" type="xsd:string" />
  </xsd:complexType>
