Function Documentation

getFieldNames()

std::vector< std::string > ros::message::getFieldNames

(

const std::string &

messageType

)

Return the names of fields of the message type (non-recursive).

Parameters

messageType

Type of the message.

Returns

The names of the fields.

Definition at line 172 of file rosmsg_cpp.cpp.

getFieldTypes()

std::vector< std::string > ros::message::getFieldTypes

(

const std::string &

messageType

)

Return the types of fields of the message type (non-recursive).

Parameters

messageType

Type of the message.

Returns

The types of the fields.

Definition at line 188 of file rosmsg_cpp.cpp.

getFullDef()

std::string ros::message::getFullDef

(

const std::string &

messageType

)

Return the full recursive definition of the message type - the same as genpy generates.

Parameters

messageType

Type of the message.

Returns

The definition. If the definition could not be found, empty string is returned.

Definition at line 146 of file rosmsg_cpp.cpp.

getMD5Sum()

std::string ros::message::getMD5Sum

(

const std::string &

messageType

)

Return the MD5 sum of the message type - the same as genpy generates.

Parameters

messageType

Type of the message.

Returns

The MD5 sum. If the message could not be found, empty string is returned.

Definition at line 154 of file rosmsg_cpp.cpp.

getMD5Text()

std::string ros::message::getMD5Text

(

const std::string &

messageType

)

Return the exact text from which the MD5 sum of the message is computed.

Parameters

messageType

Type of the message.

Returns

The MD5 sum source text.

Note

This function might be slow (a few seconds at worst).
