OIDMapping

public OIDMapping()

Method Detail

setObject

public void setObject(ObjectManager om,
                      java.lang.Object ps,
                      int[] param,
                      java.lang.Object value)

Mutator for the OID in the datastore

Overrides:

setObject in class SingleFieldMapping

Parameters:

om - The ObjectManager managing this object

ps - The Prepared Statement

param - Param numbers in the PreparedStatement for this object

value - The OID value to use

getObject

public java.lang.Object getObject(ObjectManager om,
                                  java.lang.Object rs,
                                  int[] param)

Accessor for the OID object from the result set

Overrides:

getObject in class SingleFieldMapping

Parameters:

om - ObjectManager managing this object

rs - The ResultSet

param - Array of param numbers for this object

Returns:

The OID object

getSampleValue

public java.lang.Object getSampleValue(ClassLoaderResolver clr)

Description copied from class: JavaTypeMapping

Return a sample value of the mapping type to be used for internal evaluation of type and conversion.

Specified by:

getSampleValue in class JavaTypeMapping

Parameters:

clr - TODO

Returns:

The sample value.

newLiteral

public ScalarExpression newLiteral(QueryExpression qs,
                                   java.lang.Object value)

Description copied from class: JavaTypeMapping

Creates a literal from an value. A string literal is enclosed in single quotes. for example: "literal". A string literal that includes a single quote is represented by two single quotes. for example: "literal''s". An exact numeric literal is a numeric value without a decimal point, such as 57, -957, +62. An approximate numeric literal is a numeric value in scientific notation, such as 7E3, -57.9E2, or a numeric value with a decimal, such as 7., -95.7, +6.2.

Specified by:

newLiteral in class JavaTypeMapping

Parameters:

qs - The Query statement

value - The object

Returns:

A Scalar Expression

newScalarExpression

public ScalarExpression newScalarExpression(QueryExpression qs,
                                            LogicSetExpression te)

Description copied from class: JavaTypeMapping

Creates a expression from a field name/table. e.g. tablename.fieldname; tablealias.fieldalias

Specified by:

newScalarExpression in class JavaTypeMapping

Parameters:

qs - The Query statement

te - the alias for the table

Returns:

A Scalar Expression

getJavaType

public java.lang.Class getJavaType()

Description copied from class: JavaTypeMapping

Accessor for the java type being mapped. This is the java type that the mapping represents. Some examples :

• if the field is of type "MyClass" then the mapping will be OIDMapping (or subclass) the javaType will be OID, and the type will be MyClass.
• if the field is of type "int" then the mapping will be IntegerMapping, the javaType will be Integer, and the type will be int.

The "java type" is the java-type name used in the plugin.xml mapping file

Specified by:

getJavaType in class JavaTypeMapping

Returns:

The java type
