StackTypesValidator (Soot - a J*va Optimization Framework 4.6.0-SNAPSHOT API)

java.lang.Object
- java.lang.Enum<StackTypesValidator>
- - soot.baf.toolkits.base.StackTypesValidator

All Implemented Interfaces:

Serializable, Comparable<StackTypesValidator>, BodyValidator, Validator<Body>
```
public enum StackTypesValidator
extends Enum<StackTypesValidator>
implements BodyValidator
```
Checks if the locals and the operand stack will contain the correct types for each instruction in the BafBody. NOTE: This validator assumes that each local will hold a single Type throughout the method. However, that is actually a stronger requirement than necessary for bytecode. In fact, after running the LocalPacker pass, there will likely be cases that are reported by this validator which are actually safe for bytecode.

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`boolean`	`isBasicValidator()` Basic validators run essential checks and are run always if validate is called. If this method returns false and the caller of the validator respects this property, the checks will only be run if the debug or validation option is activated.
`static StackTypesValidator`	`v()`
`void`	`validate(Body body, List<ValidationException> exceptions)` Validates the given body and saves all validation errors in the given list.
`static StackTypesValidator`	`valueOf(String name)` Returns the enum constant of this type with the specified name.
`static StackTypesValidator[]`	`values()` Returns an array containing the constants of this enum type, in the order they are declared.

```
public static final StackTypesValidator INSTANCE
```
- Method Detail
  - values
```
public static StackTypesValidator[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (StackTypesValidator c : StackTypesValidator.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static StackTypesValidator valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - v

    Description copied from interface: BodyValidator
    
    Basic validators run essential checks and are run always if validate is called.
    If this method returns false and the caller of the validator respects this property,
    the checks will only be run if the debug or validation option is activated.
    
    Specified by:
    
    isBasicValidator in interface BodyValidator
    
    Specified by:
    
    isBasicValidator in interface Validator<Body>
    
    Returns:
    
    whether this validator is a basic validator
  - validate
```
public void validate(Body body,
                     List<ValidationException> exceptions)
```
    Description copied from interface: BodyValidator
    
    Validates the given body and saves all validation errors in the given list.
    
    Specified by:
    
    validate in interface BodyValidator
    
    Specified by:
    
    validate in interface Validator<Body>
    
    Parameters:
    
    body - the body to check
    
    exceptions - the list of exceptions
