Class MappedColumnConstraint<T,​M>

  • Type Parameters:
    T - The column type.
    M - the converted (mapped) type.
    All Implemented Interfaces:
    ColumnConstraint<T>, java.lang.Comparable<ColumnConstraint<T>>

    public class MappedColumnConstraint<T,​M>
    extends java.lang.Object
    implements ColumnConstraint<T>
    Class that maps one type of column constraint into another. Typically, these are created automatically based on ColumnTypeMapper that are discovered by the system. For example, if you have a column type of "Foo", and you create a ColumnTypeMapper, then all the string constraints would now be available that column.
    • Constructor Detail

      • MappedColumnConstraint

        public MappedColumnConstraint​(ColumnTypeMapper<T,​M> mapper,
                                      ColumnConstraint<M> delegate)
        Constructs a new Mapped ColumnConstraint
        mapper - a mapper from from the column type to a mapped type.
        delegate - the column constraint of the mapped type.
    • Method Detail

      • accepts

        public boolean accepts​(T value,
                               TableFilterContext context)
        Description copied from interface: ColumnConstraint
        Compares value against the current constraint value to determine acceptance; true if value satisfies the constraints' value, false otherwise
        Specified by:
        accepts in interface ColumnConstraint<T>
        value - the column value to be tested.
        context - provides additional information about the the table and its data. This allows the filter to base its decision on information other than just the column value.
        true if the column value passes the constraint, false otherwise
      • getName

        public java.lang.String getName()
        Description copied from interface: ColumnConstraint
        Returns the name of the constraint
        Specified by:
        getName in interface ColumnConstraint<T>
        the name of the constraint.
      • getColumnType

        public java.lang.Class<T> getColumnType()
        Description copied from interface: ColumnConstraint
        Returns the column type that this constraint can be used to filter.
        Specified by:
        getColumnType in interface ColumnConstraint<T>
        the column type
      • getEditor

        public ColumnConstraintEditor<T> getEditor​(ColumnData<T> columnDataSource)
        Description copied from interface: ColumnConstraint
        Returns a ColumnConstraintEditor which will provide gui components for users to edit the constraint values.
        Specified by:
        getEditor in interface ColumnConstraint<T>
        columnDataSource - This provides the constraint with access to the column data in the table model as well as the DataProvider of the table (if it has one)
        A columnConstraintEditor for editing the constraints value.
      • getGroup

        public java.lang.String getGroup()
        Description copied from interface: ColumnConstraint
        Returns a "group" string that is used to logically group column constraints for presentation to the user
        Specified by:
        getGroup in interface ColumnConstraint<T>
        the group this constraint belongs to.
      • getConstraintValueString

        public java.lang.String getConstraintValueString()
        Description copied from interface: ColumnConstraint
        Returns the "value" of the constraint in string form

        This is used for serializing the constraint.

        Specified by:
        getConstraintValueString in interface ColumnConstraint<T>
        the "value" of the constraint in string form.
      • parseConstraintValue

        public ColumnConstraint<T> parseConstraintValue​(java.lang.String valueString,
                                                        java.lang.Object dataSource)
        Description copied from interface: ColumnConstraint
        Parses the constraint value string for deserialization purposes.
        Specified by:
        parseConstraintValue in interface ColumnConstraint<T>
        valueString - the value of the constraint in string form.
        dataSource - the DataSource from the Table.
        a new ColumnConstraint
      • copy

        public ColumnConstraint<T> copy​(ColumnConstraint<M> newDelegate)
        Creates a copy of this class using the same mapper but with a different mapped delegate.
        newDelegate - the new M type delegate column constraint.
        a copy of this class using the same mapper but with a different mapped delegate.
      • getDelegate

        public ColumnConstraint<M> getDelegate()
        Returns the delegate constraint (current value for this mapped constraint)
        the delegate constraint.
