    java.lang.Object
      org.springframework.beans.support.MutableSortDefinition

All Implemented Interfaces:
  Serializable, SortDefinition

    public class MutableSortDefinition

extends Object
implements SortDefinition, Serializable

Mutable implementation of the `SortDefinition` interface. Supports toggling the ascending value on setting the same property again.

Constructor Summary
`MutableSortDefinition()` Create an empty MutableSortDefinition, to be populated via its bean properties.
`MutableSortDefinition(boolean toggleAscendingOnSameProperty)` Create a new MutableSortDefinition.
`MutableSortDefinition(SortDefinition source)` Copy constructor: create a new MutableSortDefinition that mirrors the given sort definition.
`MutableSortDefinition(String property, boolean ignoreCase, boolean ascending)` Create a MutableSortDefinition for the given settings.

Method Summary
`boolean` `equals(Object other)`
`String` `getProperty()` Return the name of the bean property to compare.
`int` `hashCode()`
`boolean` `isAscending()` Return whether to sort ascending (true) or descending (false).
`boolean` `isIgnoreCase()` Return whether upper and lower case in String values should be ignored.
`boolean` `isToggleAscendingOnProperty()` Return whether to toggle the ascending flag if the same property gets set again (that is, `setProperty(java.lang.String)` gets called with already set property name again).
`void` `setAscending(boolean ascending)` Set whether to sort ascending (true) or descending (false).
`void` `setIgnoreCase(boolean ignoreCase)` Set whether upper and lower case in String values should be ignored.
`void` `setProperty(String property)` Set the property to compare.
`void` `setToggleAscendingOnProperty(boolean toggleAscendingOnProperty)` Set whether to toggle the ascending flag if the same property gets set again (that is, `setProperty(java.lang.String)` gets called with already set property name again).

Constructor Detail

### MutableSortDefinition

    public MutableSortDefinition()

  Create an empty MutableSortDefinition, to be populated via its bean properties.

  See Also:
    `setProperty(java.lang.String)`, `setIgnoreCase(boolean)`, `setAscending(boolean)`

### MutableSortDefinition

    public MutableSortDefinition(SortDefinition source)

  Copy constructor: create a new MutableSortDefinition that mirrors the given sort definition.

  Parameters:
    `source` - the original sort definition

### MutableSortDefinition

    public MutableSortDefinition(String property,
                                 boolean ignoreCase,
                                 boolean ascending)

  Create a MutableSortDefinition for the given settings.

  Parameters:
    `property` - the property to compare
    `ignoreCase` - whether upper and lower case in String values should be ignored
    `ascending` - whether to sort ascending (true) or descending (false)

### MutableSortDefinition

    public MutableSortDefinition(boolean toggleAscendingOnSameProperty)

  Create a new MutableSortDefinition.

  Parameters:
    `toggleAscendingOnSameProperty` - whether to toggle the ascending flag if the same property gets set again (that is, `setProperty` gets called with already set property name again).

Method Detail

### setProperty

    public void setProperty(String property)

  Set the property to compare.

  If the property was the same as the current, the sort is reversed if "toggleAscendingOnProperty" is activated, else simply ignored.

  See Also:
    `setToggleAscendingOnProperty(boolean)`

### getProperty

    public String getProperty()

  Description copied from interface: `SortDefinition`
  Return the name of the bean property to compare. Can also be a nested bean property path.

  Specified by:
    `getProperty` in interface `SortDefinition`

### setIgnoreCase

    public void setIgnoreCase(boolean ignoreCase)

  Set whether upper and lower case in String values should be ignored.

### isIgnoreCase

    public boolean isIgnoreCase()

  Description copied from interface: `SortDefinition`
  Return whether upper and lower case in String values should be ignored.

  Specified by:
    `isIgnoreCase` in interface `SortDefinition`

### setAscending

    public void setAscending(boolean ascending)

  Set whether to sort ascending (true) or descending (false).

### isAscending

    public boolean isAscending()

  Description copied from interface: `SortDefinition`
  Return whether to sort ascending (true) or descending (false).

  Specified by:
    `isAscending` in interface `SortDefinition`

### setToggleAscendingOnProperty

    public void setToggleAscendingOnProperty(boolean toggleAscendingOnProperty)

  Set whether to toggle the ascending flag if the same property gets set again (that is, `setProperty(java.lang.String)` gets called with already set property name again).

  This is particularly useful for parameter binding through a web request, where clicking on the field header again might be supposed to trigger a resort for the same field but opposite order.

### isToggleAscendingOnProperty

    public boolean isToggleAscendingOnProperty()

  Return whether to toggle the ascending flag if the same property gets set again (that is, `setProperty(java.lang.String)` gets called with already set property name again).

### equals

    public boolean equals(Object other)

  Overrides:
    `equals` in class `Object`

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `Object`
