Modifier and Type	Method	Description
void	addDescriptor(int sqlTypeCode, DdlType ddlType)	Add a mapping from the given type code to the given DdlType.
void	addDescriptor(DdlType ddlType)	Add a mapping from the type code of the given DdlType to the given DdlType.
void	addDescriptorIfAbsent(int sqlTypeCode, DdlType ddlType)	Add a mapping from the given type code to the given DdlType, if there is no mapping already present for the given type code.
void	addDescriptorIfAbsent(DdlType ddlType)	Add a mapping from the type code of the given DdlType to the given DdlType, if there is no mapping already present for that type code.
DdlType	getDescriptor(int sqlTypeCode)	Returns the registered DdlType for the given SQL type code.
Integer	getSqlTypeCode(String rawTypeName)	Returns the SqlTypes type code for the given DDL raw type name, or null if the type code cannot be determined from the registrations.
String	getTypeName(int typeCode, Long size, Integer precision, Integer scale)	Get the SQL type name for the specified JDBC type code and size, filling in the placemarkers $l, $p, and $s with the given length, precision, and scale.
String	getTypeName(int typeCode, Dialect dialect)	Get the SQL type name for the specified JDBC type code, filling in the placemarkers $l, $p, and $s with the default length, precision, and scale for the given SQL dialect.
String	getTypeName(int typeCode, Size size)	Get the SQL type name for the specified JDBC type code and size, filling in the placemarkers $l, $p, and $s with the length, precision, and scale determined by the given size object.
boolean	isTypeNameRegistered(String typeName)	Determines if there is a registered DdlType whose raw type name matches the given type name, taking into account DDL types registered by Hibernate.

Method Detail

addDescriptor

public void addDescriptor(DdlType ddlType)

Add a mapping from the type code of the given DdlType to the given DdlType.

addDescriptor

public void addDescriptor(int sqlTypeCode,
                          DdlType ddlType)

Add a mapping from the given type code to the given DdlType.

addDescriptorIfAbsent

public void addDescriptorIfAbsent(DdlType ddlType)

Add a mapping from the type code of the given DdlType to the given DdlType, if there is no mapping already present for that type code.

addDescriptorIfAbsent

public void addDescriptorIfAbsent(int sqlTypeCode,
                                  DdlType ddlType)

Add a mapping from the given type code to the given DdlType, if there is no mapping already present for the given type code.

getSqlTypeCode

public Integer getSqlTypeCode(String rawTypeName)

Returns the SqlTypes type code for the given DDL raw type name, or null if the type code cannot be determined from the registrations.

getDescriptor

public DdlType getDescriptor(int sqlTypeCode)

Returns the registered DdlType for the given SQL type code.

Note that the "long" types Types.LONGVARCHAR, Types.LONGNVARCHAR, and Types.LONGVARBINARY are considered synonyms for their non-LONG counterparts, with the only difference being that a different default length is used by default: Length.LONG instead of Length.DEFAULT.

getTypeName

public String getTypeName(int typeCode,
                          Dialect dialect)

Get the SQL type name for the specified JDBC type code, filling in the placemarkers $l, $p, and $s with the default length, precision, and scale for the given SQL dialect.

Parameters:

typeCode - the JDBC type code

dialect - the dialect which determines the default length, precision, and scale

Returns:

a SQL column type

getTypeName

public String getTypeName(int typeCode,
                          Size size)

Get the SQL type name for the specified JDBC type code and size, filling in the placemarkers $l, $p, and $s with the length, precision, and scale determined by the given size object. The returned type name should be of a SQL type large enough to accommodate values of the specified size.

Parameters:

typeCode - the JDBC type code

size - an object which determines the length, precision, and scale

Returns:

the associated type name with the smallest capacity that accommodates the given size, if available, and the default type name otherwise

getTypeName

public String getTypeName(int typeCode,
                          Long size,
                          Integer precision,
                          Integer scale)

Get the SQL type name for the specified JDBC type code and size, filling in the placemarkers $l, $p, and $s with the given length, precision, and scale. The returned type name should be of a SQL type large enough to accommodate values of the specified size.

Parameters:

typeCode - the JDBC type code

size - the SQL length, if any

precision - the SQL precision, if any

scale - the SQL scale, if any

Returns:

the associated type name with the smallest capacity that accommodates the given size, if available, and the default type name otherwise

isTypeNameRegistered

public boolean isTypeNameRegistered(String typeName)

Determines if there is a registered DdlType whose raw type name matches the given type name, taking into account DDL types registered by Hibernate.

Parameters:

typeName - the type name.

Returns:

true if there is a DDL type with the given raw type name
