OPCBrowseTag.getDataType() => system.tag.addtag()

Ignition
1

Does anyone have a x-ref for Java data type to the string data type accepted by system.tag.addtag() ?

Possible basic values are Int1, Int2, Int4, Int8, Float4, Float8, Boolean, String, DataSet, and DateTime.
Possible array values are Int4Array, Int8Array, Float8Array, BooleanArray, StringArray, DateTimeArray.

Referencing DataType:

    Int1(0, Byte.class, Types.SMALLINT),
    Int2(1, Short.class, Types.SMALLINT),
    Int4(2, Integer.class, Types.INTEGER),
    Int8(3, Long.class, Types.BIGINT),
    Float4(4, Float.class, Types.FLOAT),
    Float8(5, Double.class, Types.DOUBLE),
    Boolean(6, Boolean.class, Types.BOOLEAN),
    String(7, String.class, Types.VARCHAR),
    DateTime(8, Date.class, Types.TIMESTAMP),
    DataSet(9, Dataset.class, Types.BLOB),
    Text(10, String.class, Types.LONGVARCHAR),
    Int1Array(17, Byte[].class, Types.SMALLINT),
    Int2Array(18, Short[].class, Types.SMALLINT),
    Int4Array(11, Integer[].class, Types.INTEGER),
    Int8Array(12, Long[].class, Types.BIGINT),
    Float4Array(19, Float[].class, Types.FLOAT),
    Float8Array(13, Double[].class, Types.DOUBLE),
    BooleanArray(14, Boolean[].class, Types.BOOLEAN),
    StringArray(15, String[].class, Types.VARCHAR),
    DateTimeArray(16, Date[].class, Types.TIMESTAMP),
