Method Detail

getJavaType

public 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 String getJavaTypeForDatastoreMapping(int index)

Accessor for the name of the java-type actually used when mapping the particular datastore field. This java-type must have an entry in the datastore mappings.

Overrides:

getJavaTypeForDatastoreMapping in class TemporalMapping

Parameters:

index - requested datastore field index.

Returns:

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

getDefaultLengthAsString

protected int getDefaultLengthAsString()

Specified by:

getDefaultLengthAsString in class TemporalMapping

setObject

public void setObject(ExecutionContext ec,
                      Object preparedStatement,
                      int[] exprIndex,
                      Object value)

Description copied from class: JavaTypeMapping

Sets a value into datastoreStatement at position specified by exprIndex.

Overrides:

setObject in class SingleFieldMapping

Parameters:

ec - ExecutionContext

preparedStatement - a datastore object that executes statements in the database

exprIndex - the position of the value in the statement

value - the value

getObject

public Object getObject(ExecutionContext ec,
                        Object resultSet,
                        int[] exprIndex)

Description copied from class: JavaTypeMapping

Obtains a value from datastoreResults at position specified by exprIndex.

Overrides:

getObject in class SingleFieldMapping

Parameters:

ec - ExecutionContext

resultSet - an object returned from the datastore with values

exprIndex - the position of the value in the result

Returns:

the value
