Criteria (Concourse Java API)

Object
- Criteria

All Implemented Interfaces:

Symbol
```
public class Criteria
extends Object
implements Symbol
```
A Criteria is an object that is used to encapsulate the semantics of a complex query. Any any given time, objects of this class can exist in one of two modes: building or built. When a Criteria is built, it is guaranteed to represent a fully and well formed query that can be processed. On the other hand, when a Criteria is building it is in an incomplete state.
This class is the public interface to Criteria construction. It is meant to be used in a chained manner, where the caller initially calls where() and continues to construct the Criteria using the options available from each subsequently returned state.

  - parse
```
public static Criteria parse(String ccl)
```
    Return a Criteria object that expresses the same as the ccl statement.
    
    Parameters:
    
    ccl - the CCL statement to parse
    
    Returns:
    
    an equivalanet Criteria object
  - where
```
public static StartState where()
```

    Returns:
    
    the Criteria builder
  - at
```
public Criteria at(Timestamp timestamp)
```
    Return this Criteria with each expression (e.g. {key} {operator} {values}) pinned to the specified timestamp. NOTE: Any timestamps that are pinned to any expressions within this Criteria will be replaced by the specified timestamp.
    
    Parameters:
    
    timestamp - the Timestamp to which the returned Criteria is pinned
    
    Returns:
    
    this Criteria pinned to timestamp

```
    Overrides:
    
    equals in class Object
  - getCclString
```
public String getCclString()
```
    Return a CCL string that is equivalent to this object.
    
    Returns:
    
    an equivalent CCL string

```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object

```
public String toString()
```
    Overrides:
    
    toString in class Object
  - add
```
protected void add(Symbol symbol)
```
    Add a Symbol to this Criteria.
    
    Parameters:
    
    symbol -
  - close
