Package docking.widgets.table.constraint

Class SingleValueColumnConstraint<T>

java.lang.Object
docking.widgets.table.constraint.SingleValueColumnConstraint<T>
Type Parameters:
T - the column type
All Implemented Interfaces:
ColumnConstraint<T>, Comparable<ColumnConstraint<T>>
Direct Known Subclasses:
AtLeastColumnConstraint, AtLeastDateColumnConstraint, AtMostColumnConstraint, AtMostDateColumnConstraint
public abstract class SingleValueColumnConstraint<T> extends Object implements ColumnConstraint<T>
Abstract base class for single value constraints such as "At Most" or "At Least"

  • Field Details

    • name

      protected final String name
      This constraints' name

      It sometimes makes grammatical sense to set a more useful name than the default; while 'at least' makes sense for a number-based constraint, 'after' reads better for date-based constraints.

    • editorProvider

      protected EditorProvider<T> editorProvider

  • Constructor Details

    • SingleValueColumnConstraint

      protected SingleValueColumnConstraint(String name, T constraintValue, EditorProvider<T> editorProvider, String group)
      Constructor
      Parameters:
      name - the name of the constraint.
      constraintValue - the value of this constraint to be compared with column values.
      editorProvider - the editor provider that generates the appropriate editors for constraints of this type.
      group - the group of the constraint for visual grouping when presenting to the user.

  • Method Details

    • 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<T>
      Returns:
      the group this constraint belongs to.

    • getName

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

    • getConstraintValue

      public final T getConstraintValue()
      Returns the constraint value
      Returns:
      the constraint value

    • copy

      public abstract SingleValueColumnConstraint<T> copy(T newValue)
      subclasses must override to generate new versions of themselves but with new comparison value.
      Parameters:
      newValue - the new value to compare column values against.
      Returns:
      a new ColumnConstraint that is the same type as this constraint but with a new comparison value.

    • 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>
      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.

    • 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<T>
      Returns:
      the "value" of the constraint in string form.

    • parseConstraintValue

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

    • getColumnType

      public 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>
      Returns:
      the column type

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public boolean equals(Object o)
      Overrides:
      equals in class Object
