RequiredSolrParams (Solr 7.2.1 API)

java.lang.Object
- org.apache.solr.common.params.SolrParams
- - org.apache.solr.common.params.RequiredSolrParams

All Implemented Interfaces:

Serializable, MapSerializable, MapWriter
```
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

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`check(String... params)`
`String`	`get(String param)` get the param from params, fail if not found
`String`	`get(String param, String def)` returns the value of the param, or def if not set
`boolean`	`getBool(String param, boolean def)` Returns the boolean value of the param, or def if not set
`boolean`	`getFieldBool(String field, String param, boolean def)` Returns the boolean value of the field param, or the value for param, or def if neither is set.
`float`	`getFieldFloat(String field, String param, float def)` Returns the float value of the field param, or the value for param, or def if neither is set.
`int`	`getFieldInt(String field, String param, int def)` Returns the int value of the field param, or the value for param, or def if neither is set.
`String`	`getFieldParam(String field, String param)` returns the String value of the field parameter, "f.field.param", or the value for "param" if that is not set.
`String`	`getFieldParam(String field, String param, String def)` returns the String value of the field parameter, "f.field.param", or the value for "param" if that is not set.
`String[]`	`getFieldParams(String field, String param)` returns the String values of the field parameter, "f.field.param", or the values for "param" if that is not set.
`float`	`getFloat(String param, float def)` Returns the float value of the param, or def if not set
`int`	`getInt(String param, int def)` Returns the int value of the param, or def if not set
`Iterator<String>`	`getParameterNamesIterator()` returns an Iterator over the parameter names
`String[]`	`getParams(String param)` returns an array of the String values of a param, or null if none
`String`	`toString()` Like `SolrParams.toQueryString()`, but only replacing enough chars so that the URL may be unambiguously pasted back into a browser.
