Constructor	Description
BinaryType()	Creates the datatype for Binary.

Method Summary

Modifier and Type	Method	Description
Binary<? extends Serializable>	get(Backend backend, ResultSet resultSet, int[] pos, boolean mapNull, Integer size)	Gets the object from a result set. Must be implemented if DataType.isPredefined() returns false.
String	getJavaType()	Gets the name of the Java type.
SqlType	getSqlType(Backend backend, int index)	Gets the SQL type. For predefined types, the type must be the same for all backends and the backend argument may be null. Application specific types, however, can use different sql types for different backends and for those types the backend argument is always valid.
boolean	isJavaTypeGenerified()	Returns whether the inner type describes a generified java type. Implies DataType.isModelProvidingInnerType().
boolean	isMutable()	Returns whether type is a mutable java object. Mutable objects may change their state and must implement Freezable.
Object[]	set(Backend backend, PreparedStatement statement, int pos, Binary<? extends Serializable> object, boolean mapNull, Integer size)	Sets the object into a prepared statement. Must be implemented if DataType.isPredefined() returns false.
Binary<? extends Serializable>	valueOf(String str)	Parses a string and converts to the value of this type. The method is used to parse a literal (for example the default value defined in the model).

Constructor Details

BinaryType

public BinaryType()

Creates the datatype for Binary.

Method Details

getJavaType

public String getJavaType()

Description copied from interface: DataType

Gets the name of the Java type.

Returns:

the type

isJavaTypeGenerified

public boolean isJavaTypeGenerified()

Description copied from interface: DataType

Returns whether the inner type describes a generified java type.
Implies DataType.isModelProvidingInnerType().

Specified by:

isJavaTypeGenerified in interface DataType<Binary<? extends Serializable>>

Overrides:

isJavaTypeGenerified in class AbstractDataType<Binary<? extends Serializable>>

Returns:

true if javaType<T>, else simple type

getSqlType

public SqlType getSqlType(Backend backend,
 int index)

Description copied from interface: DataType

Gets the SQL type.
For predefined types, the type must be the same for all backends and the backend argument may be null.
Application specific types, however, can use different sql types for different backends and for those types the backend argument is always valid.

Parameters:

backend - the backend, not used by predefined types

index - the column index

Returns:

the SQL type

isMutable

public boolean isMutable()

Description copied from interface: DataType

Returns whether type is a mutable java object.
Mutable objects may change their state and must implement Freezable.

Specified by:

isMutable in interface DataType<Binary<? extends Serializable>>

Overrides:

isMutable in class AbstractDataType<Binary<? extends Serializable>>

Returns:

true if mutable and freezable

valueOf

public Binary<? extends Serializable> valueOf(String str)

Description copied from interface: DataType

Parses a string and converts to the value of this type.
The method is used to parse a literal (for example the default value defined in the model).

Notice: the method doesn't use any locale, so the results are always the same regardless of the JVM's locale.

Parameters:

str - the source string

Returns:

the value

set

public Object[] set(Backend backend,
 PreparedStatement statement,
 int pos,
 Binary<? extends Serializable> object,
 boolean mapNull,
 Integer size)
             throws SQLException

Description copied from interface: DataType

Sets the object into a prepared statement.
Must be implemented if DataType.isPredefined() returns false. Not invoked by framework otherwise.

Parameters:

backend - the database backend

statement - the prepared statement

pos - the position of the first SQL value

object - the object, may be null

mapNull - true if map null-values to non-null values

size - the optional size specified in the model

Returns:

the values stored in the prepared statement

Throws:

SQLException - if failed

get

public Binary<? extends Serializable> get(Backend backend,
 ResultSet resultSet,
 int[] pos,
 boolean mapNull,
 Integer size)
                                   throws SQLException

Description copied from interface: DataType

Gets the object from a result set.
Must be implemented if DataType.isPredefined() returns false. Not invoked by framework otherwise.

Parameters:

backend - the database backend

resultSet - the result set

pos - the column positions in the result set

mapNull - true if unmap null-values from non-null values

size - the optional size specified in the model

Returns:

the object or null if column(s) IS NULL

Throws:

SQLException - if failed
