Method Detail

initialize

protected void initialize()

Description copied from class: CharRDBMSMapping

Method to initialise the column mapping. Provides default length specifications for the CHAR column to fit the data being stored.

Overrides:

initialize in class CharRDBMSMapping

getTypeInfo

public SQLTypeInfo getTypeInfo()

Description copied from class: RDBMSMapping

Accessor for the (SQL) type info for this datastore type.

Overrides:

getTypeInfo in class CharRDBMSMapping

Returns:

The type info

getInsertionInputParameter

public String getInsertionInputParameter()

Description copied from class: RDBMSMapping

Accessor for the string to put in any retrieval datastore statement for this field. In RDBMS, this is typically a ? to be used in JDBC statements.

Overrides:

getInsertionInputParameter in class RDBMSMapping

Returns:

The input parameter

includeInFetchStatement

public boolean includeInFetchStatement()

Description copied from class: RDBMSMapping

Whether this mapping is included in the fetch statement.

Overrides:

includeInFetchStatement in class RDBMSMapping

Returns:

Whether to include in fetch statement

getUpdateInputParameter

public String getUpdateInputParameter()

Description copied from class: RDBMSMapping

Accessor for the string to put in any update datastore statements for this field. In RDBMS, this is typically a ? to be used in JDBC statements.

Overrides:

getUpdateInputParameter in class RDBMSMapping

Returns:

The input parameter.
