Detailed Description

Range state with memory management.

This class is derived from RangeState and exists to provide memory management for the c-style string members. For each c-style string member of RangeState, this class adds a std::string member to hold the string memory.

Definition at line 175 of file RangeState.h.

Hypertable::RangeStateManaged::RangeStateManaged ( const RangeState & rs )

inline

Constructor initialized with RangeState object.

Calls range_state_assignment_operator to initialize state with members of rs

Parameters

rs	Reference to RangeState object to copy

Definition at line 184 of file RangeState.h.

Definition at line 189 of file RangeState.h.

Member Function Documentation

void RangeStateManaged::clear ( )

overridevirtual

Clears state.

This method sets state to RangeState::STEADY and all other members to 0, except timestamp, which it leaves intact

Note: This method does not clear the timestamp member

Reimplemented from Hypertable::RangeState.

Definition at line 160 of file RangeState.cc.

void Hypertable::RangeStateManaged::clear_old_boundary_row ( )

inline

Clears old_boundary_row.

Clears m_old_boundary_row and sets old_boundary_row to 0.

Definition at line 305 of file RangeState.h.

void Hypertable::RangeStateManaged::clear_source ( )

inline

Clears source member.

Clears m_source and sets source to 0.

Definition at line 323 of file RangeState.h.

void Hypertable::RangeStateManaged::clear_split_point ( )

inline

Clears split point.

Clears m_split_point and sets split_point to 0.

Definition at line 287 of file RangeState.h.

void Hypertable::RangeStateManaged::clear_transfer_log ( )

inline

Clears transfer log.

Clears m_transfer_log and sets transfer_log to 0.

Definition at line 269 of file RangeState.h.

void RangeStateManaged::decode_internal	(	uint8_t	version,
		const uint8_t **	bufp,
		size_t *	remainp
	)

overrideprivatevirtual

Reads serialized representation of object from a buffer.

Parameters

version	Encoding version
bufp	Address of destination buffer pointer (advanced by call)
remainp	Address of integer holding amount of serialized object remaining

See also: encode_internal() for encoding format

Reimplemented from Hypertable::RangeState.

Definition at line 165 of file RangeState.cc.

RangeStateManaged& Hypertable::RangeStateManaged::operator= ( const RangeStateManaged & other )

inline

Assignment operator.

Casts other to RangeState type and calls range_state_assignment_operator

Parameters

other Right-hand side of assignment

Definition at line 198 of file RangeState.h.

RangeStateManaged& Hypertable::RangeStateManaged::operator= ( const RangeState & rs )

inline

Assignment operator with RangeState object.

Copies state from rs and for each c-style string member of rs, copies the contents to the corresponding std::string member of this class and then points the base class member to the std::string memory. For example, the transfer_log member is assigned as follows:

if (rs.transfer_log) {
  m_transfer_log = rs.transfer_log;
  transfer_log = m_transfer_log.c_str();
}
else
  clear_transfer_log();

Parameters

rs	Right-hand side of assignment

Definition at line 220 of file RangeState.h.

void Hypertable::RangeStateManaged::set_old_boundary_row ( const std::string & obr )

inline

Sets old boundary row.

Copies obr to m_old_boundary_row and sets old_boundary_row pointing to m_old_boundary_row.c_str()

Parameters

obr	old boundary row

Definition at line 297 of file RangeState.h.

void Hypertable::RangeStateManaged::set_source ( const std::string & src )

inline

Sets source server name.

Copies src to m_source and sets source pointing to m_source.c_str()

Parameters

src	Source server name

Definition at line 315 of file RangeState.h.

void Hypertable::RangeStateManaged::set_split_point ( const std::string & sp )

inline

Sets split point.

Copies tl to m_split_point and sets split_point pointing to m_split_point.c_str()

Parameters

sp	split point

Definition at line 279 of file RangeState.h.

void Hypertable::RangeStateManaged::set_transfer_log ( const std::string & tl )

inline

Sets transfer log.

Copies tl to m_transfer_log and sets transfer_log pointing to m_transfer_log.c_str()

Parameters

tl	Transfer log

Definition at line 261 of file RangeState.h.
