-
typeFor
public static ScalarTypeJsonMap typeFor(boolean postgres, int dbType)
Return the ScalarType for the requested dbType and postgres.
-
isMutable
public boolean isMutable()
Map is a mutable type. Use the isDirty() method to check for dirty state.- Specified by:
isMutable
in interfaceScalarType<Map>
- Overrides:
isMutable
in classScalarTypeBase<Map>
-
isDirty
public boolean isDirty(Object value)
Return true if the value should be considered dirty (and included in an update).- Specified by:
isDirty
in interfaceScalarType<Map>
- Overrides:
isDirty
in classScalarTypeBase<Map>
-
read
public Map 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
-
bind
public void bind(DataBind b, Map 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
-
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 Map 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(Map v)
Description copied from interface:ScalarType
Convert the type into a string representation.Reciprocal of parse().
-
parse
public Map 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().
-
convertFromMillis
public Map convertFromMillis(long dateTime)
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.convertFromMillis(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).
-
readData
public Map readData(DataInput dataInput) throws IOException
Description copied from interface:ScalarType
Read the value from binary input.- Throws:
IOException
-
writeData
public void writeData(DataOutput dataOutput, Map map) throws IOException
Description copied from interface:ScalarType
Write the value to binary output.- Throws:
IOException
-
jsonWrite
public void jsonWrite(com.fasterxml.jackson.core.JsonGenerator writer, Map value) throws IOException
Description copied from interface:ScalarType
Write the value to the JsonGenerator.- Throws:
IOException
-
jsonRead
public Map jsonRead(com.fasterxml.jackson.core.JsonParser parser) throws IOException
Description copied from interface:ScalarType
Read the value from JsonParser.- Throws:
IOException
-
getDocType
public DocPropertyType getDocType()
Description copied from interface:ScalarType
Return the type this maps to for JSON document stores.
