Method Detail

bind

public void bind(DataBind b,
        String value)
          throws SQLException

Description copied from interface: ScalarType

Convert (if necessary) and bind the value to the preparedStatement.

value may need to be converted from the logical bean property type to the JDBC type.

Throws:

SQLException

read

public String read(DataReader dataReader)
            throws SQLException

Description copied from interface: ScalarType

Read the value from the resultSet and convert if necessary to the logical bean property value.

Throws:

SQLException

toJdbcType

public Object toJdbcType(Object value)

Description copied from interface: ScalarType

Convert the value as necessary to the JDBC type.

Note that this should also match the type as per the getJdbcType() method.

This is typically used when the matching type is used in a where clause and we use this to ensure it is an appropriate jdbc type.

toBeanType

public String toBeanType(Object value)

Description copied from interface: ScalarType

Convert the value as necessary to the logical Bean type.

The type as per the bean property.

This is used to automatically convert id values (typically from a string to a int, long or UUID).

formatValue

public String formatValue(String t)

Description copied from interface: ScalarType

Convert the type into a string representation.

Reciprocal of parse().

parse

public String parse(String value)

Description copied from interface: ScalarType

Convert the string value to the appropriate java object.

Mostly used to support CSV, JSON and XML parsing.

Reciprocal of formatValue().

parseDateTime

public String parseDateTime(long systemTimeMillis)

Description copied from interface: ScalarType

Convert the systemTimeMillis into the appropriate java object.

For non dateTime types this will throw an exception.

isDateTimeCapable

public boolean isDateTimeCapable()

Description copied from interface: ScalarType

Return true if the type can accept long systemTimeMillis input.

This is used to determine if is is sensible to use the ScalarType.parseDateTime(long) method.

This includes the Date, Calendar, sql Date, Time, Timestamp, JODA types as well as Long, BigDecimal and String (although it generally is not expected to parse systemTimeMillis to a String or BigDecimal).

jsonWrite

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

Specified by:

jsonWrite in interface ScalarType<String>

Overrides:

jsonWrite in class ScalarTypeBase<String>

jsonFromString

public String jsonFromString(String value,
                    JsonValueAdapter ctx)

Specified by:

jsonFromString in interface ScalarType<String>

Overrides:

jsonFromString in class ScalarTypeBase<String>

jsonToString

public String jsonToString(String value,
                  JsonValueAdapter ctx)

Specified by:

jsonToString in interface ScalarType<String>

Overrides:

jsonToString in class ScalarTypeBase<String>

readData

public Object readData(DataInput dataInput)
                throws IOException

Throws:

IOException

writeData

public void writeData(DataOutput dataOutput,
             Object v)
               throws IOException

Throws:

IOException
