Method Detail

size

public java.lang.Integer size()

Specified by:

size in interface TypeIO<java.lang.Long>

convert

public MemArray convert(java.lang.Long obj,
                        MemDataArray tmpBuf)

Description copied from interface: TypeIO

Convert object to memory. Implementation may choose between creating new instance of memory and writing to existing buffer, which one is faster. This is intended for representing a db key as memory chunk. If the type is variable-size (size() returns null), the size should be set through casting tmpBuf as MemDataBuffer.

Specified by:

convert in interface TypeIO<java.lang.Long>

Parameters:

obj - the object to convert.

tmpBuf - the buffer that may be written to and returned as the result.

Returns:

memory

writeObject

public void writeObject(java.lang.Long obj,
                        MemDataArray buf)

Description copied from interface: TypeIO

Write object to memory. If the type is var-size, the size should be set through casting the buf as MemDataBuffer.

Specified by:

writeObject in interface TypeIO<java.lang.Long>

readObject

public java.lang.Long readObject(MemDataArray buf)

Description copied from interface: TypeIO

Read object from memory.

Specified by:

readObject in interface TypeIO<java.lang.Long>

isApplicable

Description copied from interface: TypeIO

Reccommended to override using instanceof!

Specified by:

dataType

public java.lang.Class<java.lang.Long> dataType()

Specified by:

dataType in interface TypeIO<java.lang.Long>
