Package org.simpleframework.xml.transform

Class DefaultMatcher

  • All Implemented Interfaces:
    Matcher
    class DefaultMatcher
extends java.lang.Object
implements Matcher
    The DefaultMatcher is a delegation object that uses several matcher implementations to correctly resolve both the stock Transform implementations and implementations that have been overridden by the user with a custom matcher. This will perform the resolution of the transform using the specified matcher, if this results in no transform then this will look for a transform within the collection of implementations.

    • Constructor Detail

      • DefaultMatcher

        public DefaultMatcher​(Matcher matcher)
        Constructor for the DefaultMatcher object. This performs resolution of Transform implementations using the specified matcher. If that matcher fails to resolve a suitable transform then the stock implementations are used.
        Parameters:
        matcher - this is the user specified matcher object

    • Method Detail

      • match

        public Transform match​(java.lang.Class type)
                throws java.lang.Exception
        This is used to match a Transform for the given type. If a transform cannot be resolved this this will throw an exception to indicate that resolution of a transform failed. A transform is resolved by first searching for a transform within the user specified matcher then searching the stock transforms.
        Specified by:
        match in interface Matcher
        Parameters:
        type - this is the type to resolve a transform object for
        Returns:
        this returns a transform used to transform the type
        Throws:
        java.lang.Exception

      • matchType

        private Transform matchType​(java.lang.Class type)
                     throws java.lang.Exception
        This is used to match a Transform for the given type. If a transform cannot be resolved this this will throw an exception to indicate that resolution of a transform failed. A transform is resolved by first searching for a transform within the user specified matcher then searching the stock transforms.
        Parameters:
        type - this is the type to resolve a transform object for
        Returns:
        this returns a transform used to transform the type
        Throws:
        java.lang.Exception
