public Class MutableSortDefinition

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

See Also

setProperty, setIgnoreCase, setAscending

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

Parameters

source:SortDefinition

the original sort definition

Create a MutableSortDefinition for the given settings.

Parameters

property:String

the property to compare

ignoreCase:boolean

whether upper and lower case in String values should be ignored

ascending:boolean

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

Create a new MutableSortDefinition.

Parameters

toggleAscendingOnSameProperty:boolean

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

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters

other:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

Annotations

@Override

Implements org.springframework.beans.support.SortDefinition.getProperty.

Doc from org.springframework.beans.support.SortDefinition.getProperty.

Return the name of the bean property to compare. Can also be a nested bean property path.

Annotations

@Override

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns:int

a hash code value for this object

Annotations

@Override

Implements org.springframework.beans.support.SortDefinition.isAscending.

Doc from org.springframework.beans.support.SortDefinition.isAscending.

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

Annotations

@Override

Implements org.springframework.beans.support.SortDefinition.isIgnoreCase.

Doc from org.springframework.beans.support.SortDefinition.isIgnoreCase.

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

Annotations

@Override

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

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

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

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

Set whether to toggle the ascending flag if the same property gets set again (that is, setProperty 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.
