True if the instance can be printed as a single table of values, false otherwise.

Definition at line 574 of file Constructor.cc.

◆ read()

bool libdap::Constructor::read ( )
override

Read the elements of Constructor marked for transmission.

Iterate over the top level members of the Constructor and read all of them that have the 'send_p' property set to true. Assume the read() methods correctly set the 'read_p' property. Once done, set 'read_p' for the Constructor itself (but not for the members, that is left up to their individual read() methods).

Returns
returns false; the return value is a relic.

◆ serialize() [2/2]

void libdap::Constructor::serialize ( D4StreamMarshaller & m,
DMR & dmr,

override

Serialize a Constructor.

Todo
See notebook for 8/21/14
Parameters
m
dmrUnused
evalUnused
filterUnused
Exceptions
Erroris thrown if the value needs to be read and that operation fails.

Definition at line 479 of file Constructor.cc.

◆ set_in_selection()

void libdap::Constructor::set_in_selection ( bool state)
override

Set the in_selection property.

Set the in_selection property for this variable and all of its children.

Parameters
stateSet the property value to state.

Definition at line 656 of file Constructor.cc.

◆ set_read_p()

void libdap::Constructor::set_read_p ( bool state)
override

Set the 'read_p' property for the Constructor and its members.

This method sets read_p for all of the Constructor. The read() method is much more selective and only sets read_p for the Constructor itself, leaving the value of the property of the members up to their read() methods. Calling this with false will clear the property of all the member variables.

Parameters
stateSet the read_p property to this state.

Definition at line 140 of file Constructor.cc.

◆ set_send_p()

void libdap::Constructor::set_send_p ( bool state)
override

Definition at line 121 of file Constructor.cc.

◆ set_var_index()

void libdap::Constructor::set_var_index ( BaseType * bt,
int i )

Set the ith element of d_vars to a variable object.

Note
This method only sets the ith element to a BaseType object. The user should be responsible to release or allocate the resource properly. Use this method cautionally.
Parameters
btA pointer to the variable that is assigned to the ith element.
iThe index of the variable to be set.

Returns
A const reference to the vector of BaseType pointers.

Definition at line 110 of file Constructor.h.

◆ width()

unsigned int libdap::Constructor::width ( bool constrained = false) const
override

This version of width simply returns the same thing as width() for simple types and Arrays. For Structure it returns the total size if constrained is false, or the size of the elements in the current projection if true.

Parameters
constrainedIf true, return the size after applying a constraint.
Returns
The number of bytes used by the variable.
Deprecated
Use width_ll()

Definition at line 156 of file Constructor.cc.

override

Get the width of the Constructor's fields.
