All Implemented Interfaces:

io.zenoh.query.IntoParameters
```
public final class Parameters
 implements IntoParameters
                    
```
Parameters of the Selector.
A thin facade over the shared string-backed implementation (io.zenoh.jni.query.Parameters), which mirrors Rust's zenoh::query::Parameters exactly. The string form follows the a=b;c=d|e;f=g format:
- parameters are separated by ; (empty chunks are skipped),
- the parameter name and value are separated by the first =,
- in the absence of =, the parameter value is considered to be the empty string,
- the value is taken verbatim (no percent-decoding),
- a duplicated parameter name is allowed: get returns the FIRST occurrence, and the duplicates survive round-tripping until an insert/remove normalizes the string.

Modifier and Type	Method	Description
`String`	`toString()`
`Parameters`	`into()`
`final Boolean`	`isEmpty()`	Returns empty if no parameters were provided.
`final Boolean`	`containsKey(String key)`	Returns true if the key is contained.
`final String`	`get(String key)`	Returns the value of the key if present (the first occurrence wins).
`final String`	`getOrDefault(String key, String default)`	Returns the value of the key if present, or if not, the default value provided.
`final List<String>`	`values(String key)`	Returns the values of the key if present.
`final String`	`insert(String key, String value)`	Inserts the key-value pair into the parameters, returning the old value in case of it being already present.
`final String`	`remove(String key)`	Removes the key parameter, returning its value.
`final Unit`	`extend(IntoParameters parameters)`	Extends the parameters with the parameters provided, overwriting any conflicting params.
`final Unit`	`extend(Map<String, String> parameters)`	Extends the parameters with the parameters provided, overwriting any conflicting params.
`final Map<String, String>`	`toMap()`	Returns a map with the key value pairs of the parameters.
`Boolean`	`equals(Object other)`

  - toString
```
 String toString()
```
  - into
```
 Parameters into()
```
  - isEmpty
```
 final Boolean isEmpty()
```
    Returns empty if no parameters were provided.
  - containsKey
```
 final Boolean containsKey(String key)
```
    Returns true if the key is contained.
  - get
```
 final String get(String key)
```
    Returns the value of the key if present (the first occurrence wins).
  - getOrDefault
```
 final String getOrDefault(String key, String default)
```
    Returns the value of the key if present, or if not, the default value provided.
  - values
```
 final List<String> values(String key)
```
    Returns the values of the key if present.
    Example:
    var parameters = Parameters.from("a=1;b=2;c=1|2|3"); assertEquals(List.of("1", "2", "3"), parameters.values("c"))
  - insert
```
 final String insert(String key, String value)
```
    Inserts the key-value pair into the parameters, returning the old value in case of it being already present.
  - remove
```
 final String remove(String key)
```
    Removes the key parameter, returning its value.
  - extend
```
 final Unit extend(IntoParameters parameters)
```
    Extends the parameters with the parameters provided, overwriting any conflicting params.
  - extend
```
 final Unit extend(Map<String, String> parameters)
```
    Extends the parameters with the parameters provided, overwriting any conflicting params.
  - toMap
```
 final Map<String, String> toMap()
```
    Returns a map with the key value pairs of the parameters. For a duplicated key the last occurrence wins (unlike get).
  - equals
```
 Boolean equals(Object other)
```
  - hashCode
```
 Integer hashCode()
```
