Detailed Description

Properties that govern how data of a certain type will be serialized on the network.

Constructor & Destructor Documentation

DynamicDataTypeSerializationProperty_t ( boolean  use_42e_compatible_alignment,
int  max_size_serialized,
int  min_size_serialized,
boolean  trim_to_size 
)

The constructor.

Member Data Documentation

boolean use_42e_compatible_alignment = false

Use RTI Connext 4.2e-compatible alignment for large primitive types.

In RTI Connext 4.2e, the default alignment for large primitive types – long, com.rti.dds.infrastructure.long, double, and com.rti.dds.infrastructure.LongDouble – was not RTPS-compliant. This compatibility mode allows applications targeting post-4.2e versions of RTI Connext to interoperate with 4.2e-based applications, regardless of the data types they use.

If this flag is not set, all data will be serialized in an RTPS-compliant manner, which for the types listed above, will not be interoperable with RTI Connext 4.2e.

int max_size_serialized = 0xffffffff

The maximum number of bytes that objects of a given type could consume when serialized on the network.

This value is used to set the sizes of certain internal middleware buffers.

The effective value of the maximum serialized size will be the value of this field or the size automatically inferred from the type's com.rti.dds.typecode.TypeCode, whichever is smaller.

int min_size_serialized = 0xffffffff

The minimum number of bytes that objects of a given type could consume when serialized on the network.

This value is used to set the sizes of certain internal middleware buffers.

Default: 0xFFFFFFFF, a sentinel that indicates that this value must be equal to the value specified in max_size_serialized.

boolean trim_to_size = false

Controls the growth of the serialization buffer in a DynamicData object.

If set to 0 (default): The buffer will not be reallocated unless the serialized size of the incoming sample is greater than the current buffer size.

If set to 1: The buffer of a DynamicData object obtained from the sample pool will be reallocated to just fit the size of the serialized data of the incoming sample. The new size cannot be smaller than min_size_serialized.
