      public StringIsNotEmptyColumnConstraint()

  • Method Details

    • getName

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

    • accepts

      public boolean accepts(String 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<String>
      Parameters:
      value - the column value to be tested.
      context - provides additional information about the table and its data. This allows the filter to base its decision on information other than just the column value.
      Returns:
      true if the column value passes the constraint, false otherwise

    • getColumnType

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

    • getEditor

      public ColumnConstraintEditor<String> getEditor(ColumnData<String> 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<String>
      Parameters:
      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)
      Returns:
      A columnConstraintEditor for editing the constraints value.

    • getGroup

      public 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<String>
      Returns:
      the group this constraint belongs to.

    • getConstraintValueString

      public 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<String>
      Returns:
      the "value" of the constraint in string form.

    • parseConstraintValue

      public ColumnConstraint<String> parseConstraintValue(String constraintValueString, Object dataSource)
      Description copied from interface: ColumnConstraint
      Parses the constraint value string for deserialization purposes.
      Specified by:
      parseConstraintValue in interface ColumnConstraint<String>
      Parameters:
      constraintValueString - the value of the constraint in string form.
      dataSource - the DataSource from the Table.
      Returns:
      a new ColumnConstraint
