public final class TypeMap
extends Object

Various mappings for schema types, e.g. to their corresponding Java object types, and Java native types. These are the official SQL type to Java type mappings. These don't quite correspond to the way the peer system works so we'll have to make some adjustments.

 -------------------------------------------------------
 SQL Type      | Java Type            | Peer Type
 -------------------------------------------------------
 CHAR          | String               | String
 VARCHAR       | String               | String
 LONGVARCHAR   | String               | String
 NUMERIC       | java.math.BigDecimal | java.math.BigDecimal
 DECIMAL       | java.math.BigDecimal | java.math.BigDecimal
 BIT           | boolean OR Boolean   | Boolean
 TINYINT       | byte OR Byte         | Byte
 SMALLINT      | short OR Short       | Short
 INTEGER       | int OR Integer       | Integer
 BIGINT        | long OR Long         | Long
 REAL          | float OR Float       | Float
 FLOAT         | double OR Double     | Double

 A couple variations have been introduced to cover cases
 that may arise, but are not covered above
 BOOLEANCHAR   | boolean OR Boolean   | String

Returns the java type which corresponds to the schema type provided. Where possible, primitive types are used.

Parameters:

schemaType - the schema type.

Returns:

name of the native java type

getJavaObjectType

public static JavaType getJavaObjectType(SchemaType schemaType)

Returns the java type which corresponds to the schema type provided. Only Object types are used.

Parameters:

schemaType - the schema type.

Returns:

the corresponding java Type.

getResultSetGetter

Parameters:

schemaType - the schema type

Returns:

the result set getter method.

isBooleanInt

public static boolean isBooleanInt(SchemaType type)

Returns true if the type is boolean in the java object and a numeric (1 or 0) in the db.

Parameters:

type - The type to check.

Returns:

true if the type is BOOLEANINT

isBooleanChar

public static boolean isBooleanChar(SchemaType type)

Returns true if the type is boolean in the java object and a String "Y" or "N" in the db.

Parameters:

type - The type to check.

Returns:

Returns:

true if the type is BIT

isTextType

public static boolean isTextType(SchemaType type)

Returns true if values for the type need to be quoted.

Parameters:

type - The type to check.

Returns:

true if values for the type need to be quoted.
