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
