StringBufferMapping

public StringBufferMapping()
Method Detail

getJavaTypeForDatastoreMapping

public java.lang.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 SingleFieldMapping
Parameters:
index - requested datastore field index.
Returns:
the name of java-type for the requested datastore field.

setObject

public void setObject(ExecutionContext ec,
                      java.lang.Object preparedStatement,
                      int[] exprIndex,
                      java.lang.Object value)
Delegates to StringMapping the storage with giving a String

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 java.lang.Object getObject(ExecutionContext ec,
                                  java.lang.Object resultSet,
                                  int[] exprIndex)
Delegates to StringMapping the retrieval of a String and constructs a StringBuffer out of it

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

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

Overrides:
getJavaType in class StringMapping
Returns:
The java type
