Constructor Details

PgCompositeType

public PgCompositeType(String name)

Creates a new PostgreSQL composite type.

Parameters:

name - type name

Method Details

appendComments

public void appendComments(SQLScript script)

Description copied from class: PgStatement

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

Overrides:

appendComments in class PgStatement

Parameters:

script - the SQL script to append comments to

appendAlterComments

public void appendAlterComments(PgStatement newObj,
 SQLScript script)

Description copied from class: PgStatement

Appends ALTER comment SQL if the comment has changed.

Overrides:

appendAlterComments in class PgStatement

Parameters:

newObj - the new statement to compare comments with

script - the SQL script to append ALTER comments to

getAttr

public AbstractColumn getAttr(String name)

Returns an attribute by name.

Parameters:

name - attribute name

Returns:

attribute or null if not found

getAttrs

public List<AbstractColumn> getAttrs()

Returns an unmodifiable list of all attributes.

Returns:

list of attributes

addAttr

public void addAttr(AbstractColumn attr)

Adds an attribute to this composite type.

Parameters:

attr - attribute to add

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 AbstractType

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.

Parameters:

hasher - the hasher instance to use for hash computation
