Detailed Description

Basic DDS value types for use in user data types.

As part of the finalization of the DDS standard, a number of DDS-specific primitive types will be introduced. By using these types, you will ensure that your data is serialized consistently across platforms even if the built-in types have different sizes on those platforms.

In this version of RTI Connext Micro, the DDS primitive types are defined using the OMG's Common Data Representation (CDR) standard.

Typedef Documentation

typedef CDR_Char DDS_Char

Defines IDL char data typeAn 8-bit quantity that encodes a single byte charater from any byte-oriented code set.

typedef CDR_Wchar DDS_Wchar

Defines IDL wchar data typeAn 16-bit quantity that encodes a wide character from any character set.

typedef CDR_Octet DDS_Octet

Defines IDL octet data typeAn 8-bit quantity that is guaranteed not to undergo any conversion when transmitted by the middleware.

typedef CDR_Short DDS_Short

Defines IDL short data typeA 16-bit signed short integer value.

typedef CDR_UnsignedShort DDS_UnsignedShort

Defines IDL unsigned short data typeA 16-bit unsigned short integer value.

typedef CDR_Long DDS_Long

Defines IDL long data typeA 32-bit signed long integer value.

typedef CDR_UnsignedLong DDS_UnsignedLong

Defines IDL unsigned long data typeA 32-bit unsigned long integer value.

typedef CDR_LongLong DDS_LongLong

Defines IDL long long data typeA 64-bit signed long long integer value.

Since some architectures do not support long long (8 bytes long), RTI has defined character arrays that match the expected size of these types.

typedef CDR_UnsignedLongLong DDS_UnsignedLongLong

Defines IDL unsigned long long data typeAn 64-bit unsigned long long integer value.

Since some architectures do not support (unsigned) long long (8 byte long), RTI has defined character arrays that match the expected size of these types.

typedef CDR_Float DDS_Float

Defines IDL float data typeA 32-bit floating point value.

typedef CDR_Double DDS_Double

Defines IDL double data typeA 64-bit floating point value.

typedef CDR_LongDouble DDS_LongDouble

Defines IDL long double data typeA 16-byte floating point value.

typedef CDR_Boolean DDS_Boolean

Defines IDL boolean data typeAn 8-bit boolean value that is used to denote a data item that can only take one of the values DDS_BOOLEAN_TRUE (1) or DDS_BOOLEAN_FALSE (0).

typedef CDR_Enum DDS_Enum

Defines IDL enum data typeEncoded as unsigned long value. The first enum identifier has the numeric value zero (0). Successive enum identifiers take ascending numeric values, in order of declaration from left to right.

typedef CDR_String DDS_String

IDL string type representation.

Has a range of ISO Latin-1 (except ASCII NULL) and a variable length.

typedef CDR_Wstring DDS_Wstring

Defines IDL wstring data typeEach character composing the string is a 16-bit quantity that encodes a wide character from any character set.
