public SortingParams()

方法详细资料

by

public SortingParams by(java.lang.String pattern)

Sort by weight in keys.

Takes a pattern that is used in order to generate the key names of the weights used for sorting. Weight key names are obtained substituting the first occurrence of * with the actual value of the elements on the list.

The pattern for a normal key/value pair is "field*" and for a value in a hash "field*->fieldname".

参数:

pattern -

返回:

the SortingParams Object

by

public SortingParams by(byte[] pattern)

Sort by weight in keys.

Takes a pattern that is used in order to generate the key names of the weights used for sorting. Weight key names are obtained substituting the first occurrence of * with the actual value of the elements on the list.

The pattern for a normal key/value pair is "field*" and for a value in a hash "field*->fieldname".

参数:

pattern -

返回:

the SortingParams Object

nosort

public SortingParams nosort()

No sorting.

This is useful if you want to retrieve a external key (using GET) but you don't want the sorting overhead.

getParams

public java.util.Collection<byte[]> getParams()

desc

public SortingParams desc()

Get the Sorting in Descending Order.

返回:

the sortingParams Object

asc

public SortingParams asc()

Get the Sorting in Ascending Order. This is the default order.

返回:

the SortingParams Object

limit

public SortingParams limit(int start,
                           int count)

Limit the Numbers of returned Elements.

参数:

start - is zero based

count -

返回:

the SortingParams Object

alpha

public SortingParams alpha()

Sort lexicographicaly. Note that Redis is utf-8 aware assuming you set the right value for the LC_COLLATE environment variable.

返回:

the SortingParams Object

get

public SortingParams get(java.lang.String... patterns)

Retrieving external keys from the result of the search.

Takes a pattern that is used in order to generate the key names of the result of sorting. The key names are obtained substituting the first occurrence of * with the actual value of the elements on the list.

The pattern for a normal key/value pair is "field*" and for a value in a hash "field*->fieldname".

To get the list itself use the char # as pattern.

Takes a pattern that is used in order to generate the key names of the result of sorting. The key names are obtained substituting the first occurrence of * with the actual value of the elements on the list.

The pattern for a normal key/value pair is "field*" and for a value in a hash "field*->fieldname".
