A normal surface filter that simply combines other filters.
This filter will combine, using boolean and or or, all of the filters that are immediate children of this packet. This packet may have children that are not normal surface filters; such children will simply be ignored.
If there are no immediate child filters, a normal surface will be accepted if this is an and filter and rejected if this is an or filter.
|
inherited |
The type of object being pointed to.
|
inline |
Creates a new surface filter that accepts all normal surfaces.
This will be an and filter.
|
inline |
Creates a new surface filter that is a clone of the given surface filter.
cloneMe | the surface filter to clone. |
|
overridevirtual |
Decides whether or not the given normal surface is accepted by this filter.
The default implementation simply returns true
.
surface | the normal surface under investigation. |
true
if and only if the given surface is accepted by this filter. Reimplemented from regina::SurfaceFilter.
|
inlineoverridevirtualinherited |
Determines if this packet depends upon its parent.
This is true if the parent cannot be altered without invalidating or otherwise upsetting this packet.
true
if and only if this packet depends on its parent. Implements regina::Packet.
|
inherited |
Returns a detailed text representation of this object.
This text may span many lines, and should provide the user with all the information they could want. It should be human-readable, should not contain extremely long lines (which cause problems for users reading the output in a terminal), and should end with a final newline. There are no restrictions on the underlying character set.
|
inlinevirtualinherited |
Returns the unique integer ID corresponding to the filtering method that is this particular subclass of SurfaceFilter.
|
inlinevirtualinherited |
Returns a string description of the filtering method that is this particular subclass of SurfaceFilter.
|

|
inlineoverrideprotectedvirtual |
Makes a newly allocated copy of this packet.
This routine should not insert the new packet into the tree structure, clone the packet's associated tags or give the packet a label. It should also not clone any descendants of this packet.
You may assume that the new packet will eventually be inserted into the tree beneath either the same parent as this packet or a clone of that parent.
parent | the parent beneath which the new packet will eventually be inserted. |
Reimplemented from regina::SurfaceFilter.
|
inline |
Sets whether this is an and or an or combination.
value | true if this is to be an and combination, or false if this is to be an or combination. |
|
inherited |
Returns a short text representation of this object.
This text should be human-readable, should fit on a single line, and should not end with a newline. Where possible, it should use plain ASCII characters.
__str__()
.
|
inline |
Determines whether this is an and or an or combination.
true
if this is an and combination, or false
if this is an or combination.
|
inherited |
Returns a short text representation of this object using unicode characters.
Like str(), this text should be human-readable, should fit on a single line, and should not end with a newline. In addition, it may use unicode characters to make the output more pleasant to read. This string will be encoded in UTF-8.
|
inlineoverridevirtual |
Writes a detailed text representation of this object to the given output stream.
This may be reimplemented by subclasses, but the parent Packet class offers a reasonable default implementation.
out | the output stream to which to write. |
Reimplemented from regina::Packet.
|
inlineoverridevirtualinherited |
Writes a short text representation of this object to the given output stream.
This must be reimplemented by subclasses.
out | the output stream to which to write. |
Implements regina::Packet.
|
overrideprotectedvirtual |
Writes a chunk of XML containing the details of this filter.
You may assume that the filter opening tag (including the filter type) has already been written, and that the filter closing tag will be written immediately after this routine is called. This routine need only write the additional details corresponding to this particular subclass of SurfaceFilter.
out | the output stream to which the XML should be written. |
Reimplemented from regina::SurfaceFilter.
|
overrideprotectedvirtualinherited |
Writes a chunk of XML containing the data for this packet only.
You may assume that the packet opening tag (including the packet type and label) has already been written, and that all child packets followed by the corresponding packet closing tag will be written immediately after this routine is called. This routine need only write the internal data stored in this specific packet.
out | the output stream to which the XML should be written. |
Implements regina::Packet.
