Constructor Details

PgDomain

public PgDomain(String name)

Creates a new PostgreSQL domain.

Parameters:

name - domain name

Method Details

getStatementType

public DbObjType getStatementType()

Description copied from interface: IStatement

Gets the type of this database object.

Specified by:

getStatementType in interface IStatement

Returns:

the database object type

getCreationSQL

public void getCreationSQL(SQLScript script)

Description copied from interface: IStatement

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 interface IStatement

Parameters:

script - the SQL script to append creation statements to

appendAlterSQL

public ObjectState appendAlterSQL(IStatement newCondition,
 SQLScript script)

Description copied from interface: IStatement

Fill script with object changes and return change type

Specified by:

appendAlterSQL in interface IStatement

Parameters:

newCondition - new object state

script - script to collect changes

Returns:

object change type

appendComments

public void appendComments(SQLScript script)

Description copied from class: AbstractStatement

Appends comment SQL to the script if this statement has comments.

Overrides:

appendComments in class AbstractStatement

Parameters:

script - the SQL script to append comments to

setDataType

public void setDataType(String dataType)

setCollation

public void setCollation(String collation)

setDefaultValue

public void setDefaultValue(String defaultValue)

setNotNull

public void setNotNull(boolean notNull)

getConstraint

public PgConstraint getConstraint(String name)

Returns a constraint by name.

Parameters:

name - constraint name

Returns:

constraint or null if not found

addConstraint

public void addConstraint(PgConstraint constraint)

Adds a constraint to this domain.

Parameters:

constraint - constraint to add

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

Parameters:

hasher - the hasher instance to use for hash computation

compare

public boolean compare(IStatement obj)

Description copied from class: AbstractStatement

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

Specified by:

compare in interface IStatement

Overrides:

compare in class AbstractStatement
