Method Details

cast

public static <T> T cast(Object obj)

Returns a given object as a typed one.

cast

public static <T,
R> Marshaller<T,R> cast(Marshaller<?,?> marshaller)

Returns a given marshaller as a typed one.

cast

public static <K,
V> Map<K,V> cast(Map<?,?> map)

Returns a given map as a typed one.

nativeOrByteArray

public static <T> Class<T> nativeOrByteArray(Class<?> clazz)

Returns same class if natively supported, else byte[].

columnClassByName

@Nullable
public static @Nullable Class<?> columnClassByName(String className)

Returns the class with the given binary name if a column can have it, or null if it cannot. The answer does not depend on the node classpath.

Use this for a name from an untrusted source instead of Class.forName(java.lang.String), which would load and initialize any class the caller can name.

marshaller

public static <T> Marshaller<T,?> marshaller(Class<T> clazz)

Returns noop marshaller if natively supported, else ByteArrayMarshaller.

columnType

public static ColumnType columnType(Class<?> clazz)

Return corresponding column type if natively supported, else byte_array.
