Method Detail

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.

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

getJavaTypeForDatastoreMapping

public java.lang.String getJavaTypeForDatastoreMapping(int index)

Accessor for the name of the java-type actually used when mapping the particular datastore field. Returns java.io.Serializable

Overrides:

getJavaTypeForDatastoreMapping in class SingleFieldMapping

Parameters:

index - requested datastore field index.

Returns:

the name of java-type for the requested datastore field.

newLiteral

public ScalarExpression newLiteral(QueryExpression qExpr,
                                   java.lang.Object literal)

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:

qExpr - The Query statement

literal - The object

Returns:

A Scalar Expression

newScalarExpression

public ScalarExpression newScalarExpression(QueryExpression qExpr,
                                            LogicSetExpression expr)

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:

qExpr - The Query statement

expr - the alias for the table

Returns:

A Scalar Expression
