Class SimpleFormat

java.lang.Object

com.sleepycat.persist.impl.Format

com.sleepycat.persist.impl.SimpleFormat

All Implemented Interfaces:

RawType, Serializable

Direct Known Subclasses:

SimpleFormat.FBigDec, SimpleFormat.FBigInt, SimpleFormat.FBool, SimpleFormat.FByte, SimpleFormat.FChar, SimpleFormat.FDate, SimpleFormat.FDouble, SimpleFormat.FFloat, SimpleFormat.FInt, SimpleFormat.FLong, SimpleFormat.FShort, SimpleFormat.FString

public abstract class SimpleFormat
extends Format

Format for simple types, including primitives. Additional methods are included to optimize the handling of primitives. Other classes such as PrimitiveArrayFormat and ReflectAccessor take advantage of these methods.

Method Detail

isSimple

public boolean isSimple()

Description copied from interface: RawType

Returns whether this is a simple type: primitive, primitive wrapper, BigInteger, BigDecimal, String or Date.

If true is returned, RawType.isPrimitive() can be called for more information, and a raw value of this type is represented as a simple type object (not as a RawObject).

If false is returned, this is a complex type, an array type (see RawType.isArray()), or an enum type, and a raw value of this type is represented as a RawObject.

Specified by:

isSimple in interface RawType

Overrides:

isSimple in class Format

Returns:

whether this is a simple type.

isPrimitive

public boolean isPrimitive()

Description copied from interface: RawType

Returns whether this type is a Java primitive: char, byte, short, int, long, float or double.

If true is returned, this is also a simple type. In other words, primitive types are a subset of simple types.

If true is returned, a raw value of this type is represented as a non-null instance of the primitive type's wrapper class. For example, an int raw value is represented as an Integer.

Specified by:

isPrimitive in interface RawType

Overrides:

isPrimitive in class Format

Returns:

whether this is a Java primitive.

readObject

public Object readObject(Object o,
                         EntityInput input,
                         boolean rawAccess)

Description copied from class: Format

Called after newInstance() to read the rest of the data bytes and fill in the object contents. If the object was read completely by newInstance(), this method does nothing. Is public only in order to implement the Reader interface. Note that this method should only be called directly in raw conversion mode or during conversion of an old format. Normally it should be called via the getReader method and the Reader interface.
