pninexus.h5cpp
¶
pninexus.io.h5cpp
is a thin wrapper around the h5cpp C++
library where every
namespace in the C++ library has a counterpart as a sub-package of
pninexus.io.h5cpp
- class pninexus.h5cpp.Path¶
This class represents an HDF5 path. A path in HDF5 is a list of link names which should be followed starting from a particular node to access another node. A path is absolute if the first node should be the root group of a particular file. In its string representation a absolute path can be identified by a leading
`/
.There are two passiblities how to construct a path:
either use the default constructor
path = Path()
or construct from a string representation
path = Path("sensors/temperature/data")
- absolute¶
Read-write property either set a path to absolute or to check whether a path is absolute.
from pninexus import h5cpp path = h5cpp.Path("/run_001/sensors/temperature") print(path) #output: /run_0001/sensors/temperature print(path.absolute) #this should print True path.absolute = False print(path) #output: run_0001/sensors/temperature
- name¶
Read-only property returning the last element of a path (basically the name of the last link in the chain)
- Return type:
str
- parent¶
Read-only property returning a path except for the last last element
path = h5cpp.Path("/run_0001/sensors/temperature") print(path.parent) #output: /run_0001/sensors
- size¶
Read-only property returning the number of elements (link names) in this path.
- Return type:
int
- append(name)¶
Append a an additional name to the end of the path
- Parameters:
name (str) – the link name to add
- __add__(other)¶
Paths can be concatenated using the + operator.
p1 = Path("/run_0001") p2 = Path("sensors/temperature/data") print(p1+p2) #output: /run_0001/sensors/temperature/data
- __eq__(other)¶
Return self==value.
Paths can be checked for equality. Two paths are considered equal if they store the same link names in the same order.
- class pninexus.h5cpp.IteratorConfig¶
Class providing configuration information for link, node and attribute iteration.
- index¶
read-write property to set and retrieve the index to use for the iteration.
- Parameters:
index (IterationIndex) – index to use for iteration
- Return type:
- order¶
read-write property to set and retrieve the iteration order
- Parameters:
order (IterationOrder) – order value
- Return type:
- link_access_list¶
read-write attribute to set and retrieve the link access property list which should be used for iteration.
- Parameters:
lapl (h5cpp.property.LinkAccessList) – link access property list
- Return type:
