# manipulators(3bobcat)

Manipulators defined in the FBB namespace

## NAME

FBB::Manipulators - Manipulators defined in the FBB namespace

## DESCRIPTION

Various manipulators are defined within the **FBB** namespace. This manual page provides an overview of the manipulators that are currently defined in the **FBB** namespace.

## MANIPULATORS

- o

  **FBB::center**:\
   defined in *bobcat/align* This manipulator can be specified when constructing an **FBB::Align** object to indicate that a table column should center its content.

-

  - o

  **FBB::decindent**:\
   defined in *bobcat/indent* This manipulator reduces the indentation level.

-

  - o

  **FBB::def**:\
   defined in *bobcat/table* This manipulator \`completes’ a **Table** object to a full rectangular object. It can be inserted into a **Table** object.

-

  - o

  **FBB::eoi**:\
   defined in *bobcat/eoi* Inserting this manipulator indicates \`end of input’ of streams initialized with classes derived from *std::streambuf* receiving information from external sources. Examples (non-exhaustive list) are found in the classes **EncryptBuf, HMacBuf, OfdBuf, Process**. Usually classes supporting the *eoi* manipulator also offer a member *eoi* performing the same actions as the manipulator.

-

  - o

  **FBB::err**:\
   defined in *bobcat/msg* Generates an error message.

-

  - o

  **FBB::errnodescr**:\
   defined in *bobcat/exception* Inserts the textual description of the current *::errno* value into the *ostream* into which the manipulator is inserted. If *errno == 0* nothing is inserted.

-

  - o

  **FBB::fatal**:\
   defined in *bobcat/msg* Generates a fatal message, followed by an **Exception(1)** exception.

-

  - o

  **FBB::fs**:\
   defined in *bobcat/tablebuf* Starts the definition of the next element in a table.

-

  - o

  **FBB::info**:\
   defined in *bobcat/msg* Generates an informational message.

-

  - o

  **FBB::incindent**:\
   defined in *bobcat/indent* This manipulator will increment the indentation level.

-

  - o

  **FBB::indent**:\
   defined in *bobcat/indent* This manipulator inserts the currently defined number of indentation blanks into an *ostream*.

-

  - o

  **FBB::indentdec**:\
   defined in *bobcat/indent* This manipulator will insert, then reduce the indentation level.

-

  - o

  **FBB::indentinc**:\
   defined in *bobcat/indent* This manipulator will insert, then increment the indentation level.

-

  - o

  **FBB::lm**:\
   defined in *bobcat/ofoldbuf* This manipulator sets the left margin of **FBB::OFoldStream** objects.

-

  - o

  **FBB::mlm**:\
   defined in *bobcat/ofoldbuf* This manipulator modifies (alters) the left margin of **FBB::OFoldStream** objects.

-

  - o

  **FBB::nlindent**:\
   defined in *bobcat/indent* This manipulator will insert a newline, then indent.

-

  - o

  **FBB::rs**:\
   defined in *bobcat/tablebuf* Starts the definition of the next row in a table.

-

  - o

  **FBB::spool**:\
   defined in *bobcat/msg* Generates a (partial) informational message.

-

  - o

  **FBB::warning**:\
   defined in *bobcat/msg* Generates a warning message.
