ScalarTypeBase

public ScalarTypeBase(Class<T> type,
              boolean jdbcNative,
              int jdbcType)

Method Detail

getLength

public int getLength()

Just return 0.

Specified by:

getLength in interface ScalarType<T>

isJdbcNative

public boolean isJdbcNative()

Description copied from interface: ScalarType

Return true if the type is native to JDBC.

If it is native to JDBC then its values/instances do not need to be converted to and from an associated JDBC type.

Specified by:

isJdbcNative in interface ScalarType<T>

getJdbcType

public int getJdbcType()

Description copied from interface: ScalarType

Return the type as per java.sql.Types that this maps to.

This type should be consistent with the toJdbcType() method in converting the type to the appropriate type for binding to preparedStatements.

Specified by:

getJdbcType in interface ScalarType<T>

getType

public Class<T> getType()

Description copied from interface: ScalarType

Return the type that matches the bean property type.

This represents the 'logical' type rather than the JDBC type this maps to.

Specified by:

getType in interface ScalarType<T>

format

public String format(Object v)

Description copied from interface: ScalarType

Convert the type into a string representation.

This assumes the value is of the correct type.

This is so that ScalarType also implements the StringFormatter interface.

Specified by:

format in interface StringFormatter

Specified by:

format in interface ScalarType<T>

isDbNull

public boolean isDbNull(Object value)

Return true if the value is null.

getDbNullValue

public Object getDbNullValue(Object value)

Returns the value that was passed in.

loadIgnore

public void loadIgnore(DataReader dataReader)

Description copied from interface: ScalarType

Ignore the reading of this value. Typically this means moving the index position in the ResultSet.

Specified by:

loadIgnore in interface ScalarDataReader<T>

Specified by:

loadIgnore in interface ScalarType<T>

accumulateScalarTypes

public void accumulateScalarTypes(String propName,
                         CtCompoundTypeScalarList list)

Description copied from interface: ScalarDataReader

Accumulate all the scalar types used by an immutable compound value type.

Specified by:

accumulateScalarTypes in interface ScalarDataReader<T>

jsonWrite

public void jsonWrite(WriteJsonBuffer buffer,
             T value,
             JsonValueAdapter ctx)

Specified by:

jsonWrite in interface ScalarType<T>

jsonToString

public String jsonToString(T value,
                  JsonValueAdapter ctx)

Specified by:

jsonToString in interface ScalarType<T>

jsonFromString

public T jsonFromString(String value,
               JsonValueAdapter ctx)

Specified by:

jsonFromString in interface ScalarType<T>
