Class PackageMatcher

java.lang.Object
org.simpleframework.xml.transform.PackageMatcher
All Implemented Interfaces:
Matcher
class PackageMatcher extends Object implements Matcher
The PackageMatcher object is used to match the stock transforms to Java packages. This is used to match useful types from the java.lang and java.util packages as well as other Java packages. This matcher groups types by their package names and attempts to search the stock transforms for a suitable match. If no match can be found this throws an exception.

    • match

      public Transform match(Class type) throws Exception
      This method attempts to perform a resolution of the transform based on its package prefix. This allows this matcher to create a logical group of transforms within a single method based on the types package prefix. If no transform can be found then this will throw an exception.
      Specified by:
      match in interface Matcher
      Parameters:
      type - this is the type to resolve a transform for
      Returns:
      the transform that is used to transform that type
      Throws:
      Exception

    • matchEnum

      private Transform matchEnum(Class type)
      This is used to resolve Transform implementations that are Enum implementations. If the type is not an enumeration then this will return null.
      Parameters:
      type - this is the type to resolve a stock transform for
      Returns:
      this will return a transform for the specified type

    • matchLanguage

      private Transform matchLanguage(Class type) throws Exception
      This is used to resolve Transform implementations that relate to the java.lang package. If the type does not resolve to a valid transform then this method will throw an exception to indicate that no stock transform exists for the specified type.
      Parameters:
      type - this is the type to resolve a stock transform for
      Returns:
      this will return a transform for the specified type
      Throws:
      Exception

    • matchMath

      private Transform matchMath(Class type) throws Exception
      This is used to resolve Transform implementations that relate to the java.math package. If the type does not resolve to a valid transform then this method will throw an exception to indicate that no stock transform exists for the specified type.
      Parameters:
      type - this is the type to resolve a stock transform for
      Returns:
      this will return a transform for the specified type
      Throws:
      Exception

    • matchUtility

      private Transform matchUtility(Class type) throws Exception
      This is used to resolve Transform implementations that relate to the java.util package. If the type does not resolve to a valid transform then this method will throw an exception to indicate that no stock transform exists for the specified type.
      Parameters:
      type - this is the type to resolve a stock transform for
      Returns:
      this will return a transform for the specified type
      Throws:
      Exception

    • matchSQL

      private Transform matchSQL(Class type) throws Exception
      This is used to resolve Transform implementations that relate to the java.sql package. If the type does not resolve to a valid transform then this method will throw an exception to indicate that no stock transform exists for the specified type.

      type - this is the type to resolve a stock transform for
      Returns:
      this will return a transform for the specified type
      Throws:
      Exception

    • matchFile

      private Transform matchFile(Class type) throws Exception
      This is used to resolve Transform implementations that relate to the java.io package. If the type does not resolve to a valid transform then this method will throw an exception to indicate that no stock transform exists for the specified type.
