构造器详细资料

CompoundComparator

public CompoundComparator()

Construct a CompoundComparator with initially no Comparators. Clients must add at least one Comparator before calling the compare method or an IllegalStateException is thrown.

CompoundComparator

public CompoundComparator(java.util.Comparator... comparators)

Construct a CompoundComparator from the Comparators in the provided array.

All Comparators will default to ascending sort order, unless they are InvertibleComparators.

参数:

comparators - the comparators to build into a compound comparator

InvertibleComparator

方法详细资料

addComparator

public void addComparator(java.util.Comparator<? extends T> comparator)

Add a Comparator to the end of the chain.

The Comparator will default to ascending sort order, unless it is a InvertibleComparator.

参数:

comparator - the Comparator to add to the end of the chain

InvertibleComparator

addComparator

public void addComparator(java.util.Comparator<? extends T> comparator,
                          boolean ascending)

Add a Comparator to the end of the chain using the provided sort order.

参数:

comparator - the Comparator to add to the end of the chain

ascending - the sort order: ascending (true) or descending (false)

setComparator

public void setComparator(int index,
                          java.util.Comparator<? extends T> comparator)

Replace the Comparator at the given index.

The Comparator will default to ascending sort order, unless it is a InvertibleComparator.

参数:

index - the index of the Comparator to replace

comparator - the Comparator to place at the given index

另请参阅:

InvertibleComparator

setComparator

public void setComparator(int index,
                          java.util.Comparator<T> comparator,
                          boolean ascending)

Replace the Comparator at the given index using the given sort order.

参数:

index - the index of the Comparator to replace

comparator - the Comparator to place at the given index

ascending - the sort order: ascending (true) or descending (false)

invertOrder

public void invertOrder()

Invert the sort order of each sort definition contained by this compound comparator.

invertOrder

public void invertOrder(int index)

Invert the sort order of the sort definition at the specified index.

参数:

index - the index of the comparator to invert

setAscendingOrder

public void setAscendingOrder(int index)

Change the sort order at the given index to ascending.

参数:

index - the index of the comparator to change

setDescendingOrder

public void setDescendingOrder(int index)

Change the sort order at the given index to descending sort.

参数:

index - the index of the comparator to change

getComparatorCount

public int getComparatorCount()

Returns the number of aggregated comparators.

compare

                   T o2)

指定者:

compare 在接口中 java.util.Comparator<T>

hashCode 在类中 java.lang.Object

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object
