Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`T`	`addConstraint(BooleanFormula constraint)` Add constraint to the context.
`void`	`close()` Closes the prover environment.
`Model`	`getModel()` Get a satisfying assignment.
`ImmutableList<Model.ValueAssignment>`	`getModelAssignments()` Get a list of satisfying assignments.
`boolean`	`isUnsat()` Check whether the conjunction of all formulas on the stack is unsatisfiable.
`void`	`pop()` Remove one formula from the environment stack.
`void`	`push()` Create backtracking point.
`default T`	`push(BooleanFormula f)` Push a backtracking point and add a formula to the environment stack, asserting it.

- Method Detail
  - push
```
@Nullable
default T push(BooleanFormula f)
```
    Push a backtracking point and add a formula to the environment stack, asserting it. The return value may be used to identify this formula later on in a query (this depends on the sub-type of the environment).
  - pop
```
void pop()
```
    Remove one formula from the environment stack.
  - addConstraint
```
@Nullable
T addConstraint(BooleanFormula constraint)
```
    Add constraint to the context.
  - push
```
void push()
```
    Create backtracking point.
  - isUnsat
```
boolean isUnsat()
         throws SolverException,
                InterruptedException
```
    Check whether the conjunction of all formulas on the stack is unsatisfiable.
    
    Throws:
    
    SolverException
    
    InterruptedException
  - getModel
```
Model getModel()
        throws SolverException
```
    Get a satisfying assignment. This should be called only immediately after an isUnsat() call that returned false. A model might contain additional symbols with their evaluation, if a solver uses its own temporary symbols. There should be at least an value-assignment for each free symbol.
    
    Throws:
    
    SolverException
  - getModelAssignments
```
ImmutableList<Model.ValueAssignment> getModelAssignments()
                                                  throws SolverException
```
    Get a list of satisfying assignments. This is equivalent to ImmutableList.copyOf(getModel()), but removes the need for calling Model.close().
    Note that if you need to iterate multiple times over the model it may be more efficient to use this method instead of getModel() (depending on the solver).
    
    Throws:
    
    SolverException
  - close
```
void close()
```
    Closes the prover environment. The object should be discarded, and should not be used after closing.
