Method Details

getFloat

public float getFloat(ResultSet resultSet, int columnIndex, JdbcTypeMapper.Context context, float defaultValue) throws SQLException

Description copied from class: JdbcTypeMapper.DataTypeMapping

Get a float value from the current row in the given ResultSet and column and convert to the target type. If the source value is null, return the given default value. A Context object is provided for additional context or "settings" regarding how to perform the conversion (for example, the source time zone). Only mappings that can logically be converted to a float need implement this method.

Overrides:

getFloat in class JdbcTypeMapper.FloatDataTypeMapping

Parameters:

resultSet - from which to extract the value.

columnIndex - ResultSet column from which to extract the value (1-based).

context - conversion context information.

defaultValue - value to return in case the source value is null.

Returns:

the converted value

Throws:

SQLException - if an error occurs

getObject

public Float getObject(ResultSet resultSet, int columnIndex, JdbcTypeMapper.Context context, Float defaultValue) throws SQLException

Description copied from class: JdbcTypeMapper.DataTypeMapping

Get a value from the current row in the given ResultSet and column and convert to the target type. If the source value is null, return the given default value. A Context object is provided for additional context or "settings" regarding how to perform the conversion (for example, the source time zone).

Overrides:

getObject in class JdbcTypeMapper.FloatDataTypeMapping

Parameters:

resultSet - from which to extract the value.

columnIndex - ResultSet column from which to extract the value (1-based).

context - conversion context information.

defaultValue - value to return in case the source value is null.

Returns:

the converted value

Throws:

SQLException - if an error occurs

bindFloat

public void bindFloat(PreparedStatement stmt, int parameterIndex, JdbcTypeMapper.Context context, float value) throws SQLException

Description copied from class: JdbcTypeMapper.DataTypeMapping

Bind the given float value to the given prepared statement. Implementations should avoid boxing and bind QueryConstants.NULL_FLOAT values as SQL NULL.

Overrides:

bindFloat in class JdbcTypeMapper.FloatDataTypeMapping

Parameters:

stmt - statement to which to bind the given value

parameterIndex - parameter index to bind

context - context information for the binding

value - value to bind

Throws:

SQLException - if an error occurs

bindObject

public void bindObject(PreparedStatement stmt, int parameterIndex, JdbcTypeMapper.Context context, Float value) throws SQLException

Description copied from class: JdbcTypeMapper.DataTypeMapping

Bind the given value to the given prepared statement. All concrete implementations must provide this method. If the given value is null or matches the Deephaven null-equivalent, it should be bound as SQL NULL.

Overrides:

bindObject in class JdbcTypeMapper.FloatDataTypeMapping

Parameters:

stmt - statement to which to bind the given value

parameterIndex - parameter index to bind

context - context information for the binding

value - value to bind

Throws:

SQLException - if an error occurs
