Constructor Detail

Heap_v10_2

public Heap_v10_2()

No arg constructor, required by Formatable.

Method Detail

getTypeFormatId

public int getTypeFormatId()

Return my format identifier.

This identifier was used for Heap in all Derby versions prior to 10.3. Databases hard upgraded to a version 10.3 and later will write the new format, see Heap. Databases created in 10.3 and later will also write the new format, see Heap.

Specified by:

getTypeFormatId in interface TypedFormat

Overrides:

getTypeFormatId in class Heap

Returns:

The identifier. (A UUID stuffed in an array of 16 bytes).

See Also:

TypedFormat.getTypeFormatId()

writeExternal

public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException

Store the stored representation of the column value in the stream.

For more detailed description of the format see documentation at top of file.

Specified by:

writeExternal in interface java.io.Externalizable

Overrides:

writeExternal in class Heap

Throws:

java.io.IOException

Externalizable.writeExternal(java.io.ObjectOutput)
