Class ModifiableSolrParams

java.lang.Object

org.apache.solr.common.params.SolrParams

org.apache.solr.common.params.ModifiableSolrParams

All Implemented Interfaces:

Serializable, Iterable<Map.Entry<String,String[]>>, MapSerializable, MapWriter, NavigableObject

Direct Known Subclasses:

SolrQuery

public class ModifiableSolrParams
extends SolrParams

This class is similar to MultiMapSolrParams except you can edit the parameters after it is initialized. It has helper functions to set/add integer and boolean param values.

Since:

solr 1.3

Constructor Detail

ModifiableSolrParams

public ModifiableSolrParams()

ModifiableSolrParams

public ModifiableSolrParams(Map<String,String[]> v)

Constructs a new ModifiableSolrParams directly using the provided Map<String,String[]>

ModifiableSolrParams

public ModifiableSolrParams(SolrParams params)

Constructs a new ModifiableSolrParams, copying values from an existing SolrParams

Method Detail

of

public static ModifiableSolrParams of(SolrParams params)

If the input params are of type MofifiableSolrParams, returns the input, otherwise, constructs a new ModifiableSolrParams, copying values from the given params. If params is null, returns an empty ModifiableSolrParams instance.

size

public int size()

getMap

public Map<String,String[]> getMap()

setNonNull

public ModifiableSolrParams setNonNull(String name,
                                       Object val)

set

public ModifiableSolrParams set(String name,
                                String... val)

Replace any existing parameter with the given name. if val==null remove key from params completely.

set

public ModifiableSolrParams set(String name,
                                int val)

set

public ModifiableSolrParams set(String name,
                                boolean val)

add

public ModifiableSolrParams add(String name,
                                String... val)

Add the given values to any existing name

Parameters:

name - Key

val - Array of value(s) added to the name. NOTE: If val is null or a member of val is null, then a corresponding null reference will be included when a get method is called on the key later.

Returns:

this

add

public void add(SolrParams params)

Add all of the params provided in the parameter to this params. Any current value(s) for the same key will be overridden.

remove

public String[] remove(String name)

remove a field at the given name

clear

public void clear()

clear all parameters

remove

public boolean remove(String name,
                      String value)

remove the given value for the given name

Returns:

true if the item was removed, false if null or not present

get

public String get(String param)

Description copied from class: SolrParams

Returns the first String value of a param, or null if not set. To get all, call SolrParams.getParams(String) instead.

Specified by:

get in class SolrParams

getParameterNamesIterator

public Iterator<String> getParameterNamesIterator()

Description copied from class: SolrParams

Returns an Iterator over the parameter names. If you were to call a getter for this parameter, you should get a non-null value. Since you probably want the value, consider using Java 5 for-each style instead for convenience since a SolrParams implements Iterable.

Specified by:

getParameterNamesIterator in class SolrParams

getParameterNames

public Set<String> getParameterNames()

getParams

public String[] getParams(String param)

Description copied from class: SolrParams

returns an array of the String values of a param, or null if no mapping for the param exists.

Specified by:

getParams in class SolrParams

iterator

public Iterator<Map.Entry<String,String[]>> iterator()

Description copied from class: SolrParams

Returns an Iterator of Map.Entry providing a multi-map view. Treat it as read-only.

Specified by:

iterator in interface Iterable<Map.Entry<String,String[]>>

Overrides:

iterator in class SolrParams
