                                 boolean checkFullyPopulated)

TinyBeanPropertyRowMapper

Method Detail

newInstance

public static <T> TinyBeanPropertyRowMapper<T> newInstance(Class<T> mappedClass)

initBeanWrapper

protected void initBeanWrapper(org.springframework.beans.BeanWrapper bw)

mapRow

public T mapRow(ResultSet rs,
                int rowNumber)
         throws SQLException

Specified by:

mapRow in interface org.springframework.jdbc.core.RowMapper<T>

Throws:

SQLException

isCheckFullyPopulated

public boolean isCheckFullyPopulated()

Return whether we're strictly validating that all bean properties have been mapped from corresponding database fields.

setCheckFullyPopulated

public void setCheckFullyPopulated(boolean checkFullyPopulated)

Set whether we're strictly validating that all bean properties have been mapped from corresponding database fields.

Default is false, accepting unpopulated properties in the target bean.

isPrimitivesDefaultedForNullValue

public boolean isPrimitivesDefaultedForNullValue()

Return whether we're defaulting Java primitives in the case of mapping a null value from corresponding database fields.

setPrimitivesDefaultedForNullValue

public void setPrimitivesDefaultedForNullValue(boolean primitivesDefaultedForNullValue)

Set whether we're defaulting Java primitives in the case of mapping a null value from corresponding database fields.

Default is false, throwing an exception when nulls are mapped to Java primitives.

getColumnValue

protected Object getColumnValue(ResultSet rs,
                                int index,
                                PropertyDescriptor pd)
                         throws SQLException

Retrieve a JDBC object value for the specified column.

The default implementation calls JdbcUtils.getResultSetValue(ResultSet, int, Class). Subclasses may override this to check specific value types upfront, or to post-process values return from getResultSetValue.

Parameters:

rs - is the ResultSet holding the data

index - is the column index

pd - the bean property that each result object is expected to match (or null if none specified)

Returns:

the Object value

Throws:

SQLException - in case of extraction failure
