Constructor Detail

EnumLiteral

public EnumLiteral(SQLStatement stmt,
                   org.datanucleus.store.mapped.mapping.JavaTypeMapping mapping,
                   Object value,
                   String parameterName)

Constructor for an Enum literal with a value.

Parameters:

stmt - the SQL statement

mapping - the mapping

value - the value

parameterName - Name of the parameter that this represents if any (as JDBC "?")

Overrides:

setJavaTypeMapping in class EnumExpression

getValue

public Object getValue()

Description copied from interface: SQLLiteral

Accessor to the literal value

Specified by:

getValue in interface SQLLiteral

Returns:

the value of the literal

isParameter

public boolean isParameter()

Overrides:

isParameter in class SQLExpression

setNotParameter

public void setNotParameter()
