pdk.flow.xml.XmlTypeInfo

contains functions to operate with XML TypeInfo variables

This functions are based on Java org.w3c.dom package classes.

You can always rely on Java documentation and examples!

Constants

Name	Description	Value
DERIVATION_EXTENSION	If the document's schema is an XML Schema [XML Schema Part 1] , this constant represents the derivation by extension.	2
DERIVATION_LIST	If the document's schema is an XML Schema [XML Schema Part 1] , this constant represents the list.	8
DERIVATION_RESTRICTION	If the document's schema is an XML Schema [XML Schema Part 1] , this constant represents the derivation by restriction if complex types are involved, or a restriction if simple types are involved.	1
DERIVATION_UNION	If the document's schema is an XML Schema [XML Schema Part 1] , this constant represents the union if simple types are involved.	4

Functions

• getTypeNamespace

• isDerivedFrom

---

getConstantName

Returns name of the constant by value.

Arguments:

• constantValue :: pdk.core.Integer

Result:

• output :: pdk.core.String

Possible exceptions

• NullPointerException - throws if the constantValue is NULL

---

getConstantValue

Returns value of the constant by name.

Arguments:

• constantName :: pdk.core.String

Result:

• output :: pdk.core.Integer

Possible exceptions

• NullPointerException - throws if the constantName is NULL

---

getTypeName

The name of a type declared for the associated element or attribute, or null if unknown.

Arguments:

• type :: pdk.net.xml.TypeInfo

Result:

• output :: pdk.core.String

Possible exceptions

• NullPointerException - throws if the type is NULL

---

getTypeNamespace

The namespace of the type declared for the associated element or attribute or null if the element does not have declaration or if no namespace information is available.

Arguments:

• type :: pdk.net.xml.TypeInfo

Result:

• output :: pdk.core.String

Possible exceptions

• NullPointerException - throws if the type is NULL

---

isDerivedFrom

This method returns if there is a derivation between the reference type definition, i.e. the TypeInfo on which the method is being called, and the other type definition, i.e. the one passed as parameters.

Arguments:

• type :: pdk.net.xml.TypeInfo
• typeNamespaceArg :: pdk.core.String - the namespace of the other type definition.
• typeNameArg :: pdk.core.String - the name of the other type definition.
• derivationMethod :: pdk.core.String - the type of derivation and conditions applied between two types, as described in the list of constants provided in this interface.

Result:

• output :: pdk.core.Boolean - If the document's schema is a DTD or no schema is associated with the document, this method will always return false . If the document's schema is an XML Schema, the method will return true if the reference type definition is derived from the other type definition according to the derivation parameter. If the value of the parameter is 0 (no bit is set to 1 for the derivationMethod parameter), the method will return true if the other type definition can be reached by recursing any combination of {base type definition}, {item type definition}, or {member type definitions} from the reference type definition.

Possible exceptions

• NullPointerException - throws if the type , typeNamespaceArg , typeNameArg or derivationMethod is NULL
