Class RecordMapping

java.lang.Object

com.devexperts.qd.ng.RecordMapping

public abstract class RecordMapping
extends Object

Base class for record mappings. Record mapping maps record field indices onto specific getters and setters. Actual implementation of this class store the indices of the corresponding data record fields and provide a set of methods like T getXXX(RecordCursor cursor) and void setXXX(RecordCursor cursor, T value) for them.

Constructor Detail

RecordMapping

protected RecordMapping(DataRecord record)

Creates record mapping for a specified record.

Method Detail

putNonDefaultPropertyName

protected void putNonDefaultPropertyName(String localName,
                                         String propertyName)

Defines non-default property name in descendant classes constructors.

getNonDefaultPropertyName

public String getNonDefaultPropertyName(String localName)

Returns field property name that corresponding to its local name in case when it is not default.

Returns:

non-default local name or null if default.

getEventSymbolByQDSymbol

public Object getEventSymbolByQDSymbol(String qdSymbol)

getQDSymbolByEventSymbol

public String getQDSymbolByEventSymbol(Object symbol)

getRecord

public final DataRecord getRecord()
