Constructor Details

PgJdbcType

public PgJdbcType(long oid,
 String typeName,
 long typelem,
 long typarray,
 String parentSchema,
 String elemname,
 long lastSysOid)

Creates a new JDBC type representation. Array types have names beginning with underscore and have 0 in typarray column. Vector types have non-zero typarray values and are not converted to simple arrays.

Parameters:

oid - the type OID

typeName - the type name

typelem - the element type OID for arrays

typarray - the array type OID

parentSchema - the schema containing this type

elemname - the element type name for arrays

lastSysOid - the last system OID for dependency checking

Method Details

getSchemaQualifiedName

public String getSchemaQualifiedName(String targetSchemaName)

Returns the schema-qualified type name, applying aliases for pg_catalog types.

Parameters:

targetSchemaName - the target schema name for qualification comparison

Returns:

the qualified type name

getSchemaQualifiedName

public String getSchemaQualifiedName()

Returns the schema-qualified type name with empty target schema.

Returns:

the qualified type name

getFullName

public String getFullName(String targetSchemaName)

Returns the full type name with schema qualification and array notation. If the type's schema differs from targetSchemaName, the returned name is schema-qualified. Array types have "[]" appended to the end.

Parameters:

targetSchemaName - the target schema name for qualification comparison

Returns:

the full type name with array notation if applicable

getFullName

public String getFullName()

Returns the full type name with empty target schema.

Returns:

the full type name with array notation if applicable

toReference

public ObjectReference toReference()

Returns the ObjectReference representation containing the type's schema and name.

Returns:

the ObjectReference for this type

addTypeDepcy

public void addTypeDepcy(AbstractStatement st)

Adds this type as a dependency to the specified statement if it's a user type.

Parameters:

st - the statement to add the dependency to
