Method Detail

isKnownImmutable

public boolean isKnownImmutable(Class<?> cls)

Specified by:

isKnownImmutable in interface KnownImmutable

checkImmutable

public CheckImmutableResponse checkImmutable(Class<?> cls)

Description copied from interface: TypeManager

Check if the type is immutable using reflection.

Specified by:

checkImmutable in interface TypeManager

recursiveCreateScalarDataReader

public ScalarDataReader<?> recursiveCreateScalarDataReader(Class<?> cls)

Description copied from interface: TypeManager

Create ScalarDataReader's for the Immutable compound type.

Specified by:

recursiveCreateScalarDataReader in interface TypeManager

recursiveCreateScalarTypes

public ScalarType<?> recursiveCreateScalarTypes(Class<?> cls)

Description copied from interface: TypeManager

Create ScalarTypes for this Immutable Value Object type.

Specified by:

recursiveCreateScalarTypes in interface TypeManager

add

public void add(ScalarType<?> scalarType)

Register a custom ScalarType.

Specified by:

add in interface TypeManager

logAdd

protected void logAdd(ScalarType<?> scalarType)

getCompoundType

public CtCompoundType<?> getCompoundType(Class<?> type)

Description copied from interface: TypeManager

Return the Internal CompoundType handler for a given compound type.

Specified by:

getCompoundType in interface TypeManager

getScalarType

public ScalarType<?> getScalarType(int jdbcType)

Return the ScalarType for the given jdbc type as per java.sql.Types.

Specified by:

getScalarType in interface TypeManager

Parameters:

jdbcType - as per java.sql.Types

getScalarType

public <T> ScalarType<T> getScalarType(Class<T> type)

This can return null if no matching ScalarType is found.

Specified by:

getScalarType in interface TypeManager

getScalarDataReader

public ScalarDataReader<?> getScalarDataReader(Class<?> propertyType,
                                      int sqlType)

getScalarDataReader

public ScalarDataReader<?> getScalarDataReader(Class<?> type)

getScalarType

public <T> ScalarType<T> getScalarType(Class<T> type,
                              int jdbcType)

Return a ScalarType for a given class.

Used for java.util.Date and java.util.Calendar which can be mapped to different jdbcTypes in a single system.

Specified by:

getScalarType in interface TypeManager

convert

public Object convert(Object value,
             int toJdbcType)

Convert the Object to the required datatype. The

Parameters:

value - the Object value

toJdbcType - the type as per java.sql.Types.

createEnumScalarType

public ScalarType<?> createEnumScalarType(Class<?> enumType)

Create a ScalarType for an Enum that has additional mapping.

The reason for this is that often in a DB there will be short codes used such as A,I,N rather than the ACTIVE, INACTIVE, NEW. So there really needs to be a mapping from the nicely named enumeration values to the typically much shorter codes used in the DB.

Specified by:

createEnumScalarType in interface TypeManager

initialiseCustomScalarTypes

protected void initialiseCustomScalarTypes(BootupClasses bootupClasses)

Automatically find any ScalarTypes by searching through the class path.

In avaje.properties define a list of packages in which ScalarTypes are found. This will search for any class that implements the ScalarType interface and register it with this TypeManager.

initialiseScalarConverters

protected void initialiseScalarConverters(BootupClasses bootupClasses)

initialiseCompoundTypes

protected void initialiseCompoundTypes(BootupClasses bootupClasses)

createCompoundScalarDataReader

protected CtCompoundType createCompoundScalarDataReader(Class<?> compoundTypeClass,
                                            CompoundType<?> compoundType,
                                            String info)

initialiseJodaTypes

protected void initialiseJodaTypes()

Detect if Joda classes are in the classpath and if so register the Joda data types.

initialiseStandard

protected void initialiseStandard(int platformClobType,
                      int platformBlobType)

Register all the standard types supported. This is the standard JDBC types plus some other common types such as java.util.Date and java.util.Calendar.
