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: 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

appendAlterComments

public void appendAlterComments(AbstractStatement newObj,
 SQLScript script)

Description copied from class: AbstractStatement

Appends ALTER comment SQL if the comment has changed.

Overrides:

appendAlterComments in class AbstractStatement

Parameters:

newObj - the new statement to compare comments with

script - the SQL script to append ALTER comments to

getAttr

public PgColumn getAttr(String name)

Returns an attribute by name.

Parameters:

name - attribute name

Returns:

attribute or null if not found

getAttrs

public List<Pair<String,String>> getAttrs()

Description copied from interface: ICompositeType

Returns list of all attributes.

Specified by:

getAttrs in interface ICompositeType

Returns:

list of attributes

addAttr

public void addAttr(PgColumn attr)

Adds an attribute to this composite type.

Parameters:

attr - attribute to add

getAttrType

public String getAttrType(String attrName)

Description copied from interface: ICompositeType

Returns the type of the specified attribute.

Specified by:

getAttrType in interface ICompositeType

Parameters:

attrName - the attribute name

Returns:

the attribute type, or null if not found

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
