public StatementTablePermission(UUID tableUUID,
                                int privType)
```
    Constructor for StatementTablePermission. Creates an instance of table permission requested for the given access.
    
    Parameters:
    
    tableUUID - UUID of the table
    
    privType - Access privilege requested
- Method Detail
  - getPrivType
```
public int getPrivType()
```
    Return privilege access requested for this access descriptor
    
    Returns:
    
    Privilege access
  - getTableUUID
```
public UUID getTableUUID()
```
    Return table UUID for this access descriptor
    
    Returns:
    
    Table UUID
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Routine to check if another instance of access descriptor matches this. Used to ensure only one access descriptor for a table of given privilege is created. Otherwise, every column reference from a table may create a descriptor for that table.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    obj - Another instance of StatementPermission
    
    Returns:
    
    true if match
  - hashCode
```
public int hashCode()
```
    Return hash code for this instance

    Description copied from class: StatementPermission
    
    Get the PermissionsDescriptor for the passed authorization id for this object. This method gets called during the execution phase of create view/constraint/trigger. The return value of this method is saved in dependency system to keep track of views/constraints/triggers dependencies on required permissions. This happens in execution phase after it has been established that passed authorization id has all the permissions it needs to create that view/constraint/trigger. Which means that we can only get to writing into dependency system once all the required privileges are confirmed.
    
    Specified by:
    
    getPermissionDescriptor in class StatementPermission
    
    Parameters:
    
    authid - AuthorizationId
    
    dd - DataDictionary
    
    Returns:
    
    PermissionsDescriptor The PermissionsDescriptor for the passed authorization id on this object
    
    Throws:
    
    StandardException
