Constructor Details

PgPolicy

public PgPolicy(String name)

Creates a new PostgreSQL policy.

Parameters:

name - policy name

Method Details

setCheck

public void setCheck(String check)

getCreationSQL

public void getCreationSQL(SQLScript script)

Description copied from class: PgStatement

Generates the SQL statements needed to create this database object. This is an abstract method that must be implemented by subclasses to provide the specific CREATE SQL for each object type.

Specified by:

getCreationSQL in class PgStatement

Parameters:

script - the SQL script to append creation statements to

appendAlterSQL

public ObjectState appendAlterSQL(PgStatement newCondition,
 SQLScript script)

Description copied from class: PgStatement

Fill script with object changes and return change type

Specified by:

appendAlterSQL in class PgStatement

Parameters:

newCondition - new object state

script - script to collect changes

Returns:

object change type

compare

public boolean compare(PgStatement obj)

Description copied from class: PgStatement

This method does not account for nested child PgStatements. Shallow version of PgStatement.equals(Object)

Overrides:

compare in class AbstractPolicy

computeHash

public void computeHash(Hasher hasher)

Description copied from interface: IHashable

Computes the hash of the implementing object using the provided hasher. The implementation should call appropriate put methods on the hasher for all fields that should contribute to the hash value.

Specified by:

computeHash in interface IHashable

Overrides:

computeHash in class AbstractPolicy

Parameters:

hasher - the hasher instance to use for hash computation

isSubElement

public boolean isSubElement()

Description copied from class: PgStatement

Checks if this statement is a sub-element of another statement.

Overrides:

isSubElement in class PgStatement

Returns:

true if this is a sub-element

getContainingSchema

public AbstractSchema getContainingSchema()

Description copied from interface: ISearchPath

Gets the schema that contains this object.

Specified by:

getContainingSchema in interface ISearchPath

Returns:

the containing schema
