Method Detail

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.

Overrides:

newLiteral in class SqlTimestampMapping

Parameters:

qs - The Query statement

value - The object

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

Overrides:

getJavaType in class SqlTimestampMapping

Returns:

The java type

getDefaultLength

public int getDefaultLength(int index)

Method to return the default length of this type in the datastore. java.util.Date requires 28 characters ("dow mon dd hh:mm:ss zzz yyyy")

Overrides:

getDefaultLength in class SingleFieldMapping

Parameters:

index - The index position

Returns:

The default length
