Method Summary

Modifier and Type	Method	Description
java.math.BigDecimal	get(Backend backend, java.sql.ResultSet resultSet, int[] pos, boolean mapNull, java.lang.Integer size)	Gets the object from a result set. Must be implemented if DataType.isPredefined() returns false.
java.lang.String	getJavaType()	Gets the name of the Java type.
SqlType	getSqlType(int index)	Gets the SQL type.
java.lang.Object[]	set(Backend backend, java.sql.PreparedStatement statement, int pos, java.math.BigDecimal object, boolean mapNull, java.lang.Integer size)	Sets the object into a prepared statement. Must be implemented if DataType.isPredefined() returns false.
java.math.BigDecimal	valueOf(java.lang.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).

Method Detail

getJavaType

public java.lang.String getJavaType()

Description copied from interface: DataType

Gets the name of the Java type.

Returns:

the type

getSqlType

public SqlType getSqlType(int index)

Description copied from interface: DataType

Gets the SQL type.

Parameters:

index - the column index

Returns:

the SQL type

valueOf

public java.math.BigDecimal valueOf(java.lang.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 java.lang.Object[] set(Backend backend,
                              java.sql.PreparedStatement statement,
                              int pos,
                              java.math.BigDecimal object,
                              boolean mapNull,
                              java.lang.Integer size)
                       throws java.sql.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:

java.sql.SQLException - if failed

get

public java.math.BigDecimal get(Backend backend,
                                java.sql.ResultSet resultSet,
                                int[] pos,
                                boolean mapNull,
                                java.lang.Integer size)
                         throws java.sql.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:

java.sql.SQLException - if failed
