    • Constructor Detail

      • ComparisonFilter

        public ComparisonFilter()
        Default constructor (necessary for the ExternalizableLite interface).

      • toExpression

        public String toExpression()
        Description copied from interface: Filter
        Return a string expression for this filter.
        Returns:
        a string expression for this filter
      • getOperator

        protected String getOperator()
      • getValue

        public C getValue()
        Get the object to compare the reflection result with.
        Returns:
        the object to compare the reflection result with
      • toStringValue

        protected String toStringValue()
        Return the string representation of the value.
        Returns:
        the string representation of the value
      • equals

        public boolean equals​(Object o)
        Compare the ComparisonFilter with another object to determine equality. Two ComparisonFilter objects are considered equal iff they belong to exactly the same class and their extractor and value are equal.
        Overrides:
        equals in class Object
        Returns:
        true iff this ComparisonFilter and the passed object are equivalent ComparisonFilters
      • hashCode

        public int hashCode()
        Determine a hash value for the ComparisonFilter object according to the general Object.hashCode() contract.
        Overrides:
        hashCode in class Object
        Returns:
        an integer hash value for this ComparisonFilter object
      • toString

        public String toString()
        Return a human-readable description for this Filter.
        Overrides:
        toString in class Object
        Returns:
        a String description of the Filter

                          throws IOException
        Restore the contents of this object by loading the object's state from the passed DataInput object.
        Specified by:
        readExternal in interface ExternalizableLite
        Overrides:
        readExternal in class ExtractorFilter<T,​E>
        Parameters:
        in - the DataInput stream to read data from in order to restore the state of this object
        Throws:
        IOException - if an I/O exception occurs
        NotActiveException - if the object is not in its initial state, and therefore cannot be deserialized into
