Class AtLeastColumnConstraint<T extends java.lang.Comparable<T>>

java.lang.Object

docking.widgets.table.constraint.SingleValueColumnConstraint<T>

docking.widgets.table.constraint.AtLeastColumnConstraint<T>

Type Parameters:

T - the column type.

All Implemented Interfaces:

ColumnConstraint<T>, java.lang.Comparable<ColumnConstraint<T>>

Constructor	Description
AtLeastColumnConstraint(java.lang.String name, T minValue, EditorProvider<T> editorProvider, java.lang.String group)	Constructs a new AtLeastColumnConstraint with a minimum value, constraint name, and group
AtLeastColumnConstraint(T minValue, EditorProvider<T> editorProvider)	Constructs a new AtLeastColumnConstraint with a default name, default group and a minimum value.

Method Summary

Modifier and Type	Method	Description
boolean	accepts(T value, TableFilterContext context)	Compares value against the current constraint value to determine acceptance; true if value satisfies the constraints' value, false otherwise
SingleValueColumnConstraint<T>	copy(T newValue)	subclasses must override to generate new versions of themselves but with new comparison value.

Constructor Detail

AtLeastColumnConstraint

public AtLeastColumnConstraint(T minValue,
                               EditorProvider<T> editorProvider)

Constructs a new AtLeastColumnConstraint with a default name, default group and a minimum value.

Parameters:

minValue - the value for which all acceptable column values must be greater than or equal.

editorProvider - an object that can provide a ConstraintEditor for this constraint type.

AtLeastColumnConstraint

public AtLeastColumnConstraint(java.lang.String name,
                               T minValue,
                               EditorProvider<T> editorProvider,
                               java.lang.String group)

Constructs a new AtLeastColumnConstraint with a minimum value, constraint name, and group

Parameters:

name - the name of the constraint. For some types T, the default "At Least" may not be best.

minValue - the value for which all acceptable column values must be greater than or equal.

editorProvider - an object that can provide a ConstraintEditor for this constraint type.

group - the name of the group used to organize the list of constraints for a column.

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

Parameters:

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.

Returns:

true if the column value passes the constraint, false otherwise

copy

public SingleValueColumnConstraint<T> copy(T newValue)

Description copied from class: SingleValueColumnConstraint

subclasses must override to generate new versions of themselves but with new comparison value.

Specified by:

copy in class SingleValueColumnConstraint<T extends java.lang.Comparable<T>>

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.
