Method Detail

startKeyValuePair

void startKeyValuePair()

Prepares key and value writers to write new values. Must be invoked before writing data to these fields.

endKeyValuePair

void endKeyValuePair()

Finalizes writing values to key and value writers. Must be invoked after the values for the fields are written.

getKeyWriter

FieldWriter getKeyWriter()

getValueWriter

FieldWriter getValueWriter()
