Class RequiredSolrParams

java.lang.Object

All Implemented Interfaces:

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

public class RequiredSolrParams
extends SolrParams

This is a simple wrapper to SolrParams that will throw a 400 exception if you ask for a parameter that does not exist. Fields specified with

In short, any value you for from a RequiredSolrParams will return a valid non-null value or throw a 400 exception. (If you pass in null as the default value, you can get a null return value)

Since:

solr 1.2

RequiredSolrParams

public RequiredSolrParams(SolrParams params)

Method Detail

get

public String get(String param)

get the param from params, fail if not found *

Specified by:

get in class SolrParams

getFieldParam

public String getFieldParam(String field,
                            String param)

Description copied from class: SolrParams

returns the String value of the field parameter, "f.field.param", or the value for "param" if that is not set.

Overrides:

getFieldParam in class SolrParams

getFieldParams

public String[] getFieldParams(String field,
                               String param)

Description copied from class: SolrParams

returns the String values of the field parameter, "f.field.param", or the values for "param" if that is not set.

Overrides:

getFieldParams in class SolrParams

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

getParameterNamesIterator

public Iterator<String> getParameterNamesIterator()

returns an Iterator over the parameter names

Specified by:

getParameterNamesIterator in class SolrParams

toString

public String toString()

Description copied from class: SolrParams

Like SolrParams.toQueryString(), but only replacing enough chars so that the URL may be unambiguously pasted back into a browser. This method can be used to properly log query parameters without making them unreadable.

Characters with a numeric value less than 32 are encoded. &,=,%,+,space are encoded.

Overrides:

toString in class SolrParams
