StcsProps
-
Return all properties when reading an STC-S document?
- Description:
- This is a boolean attribute which controls what is returned
by the
astRead
function when it is used to read from an StcsChan.
If StcsProps is set non-zero, then a KeyMap containing all the
properties read from the STC-S document will be returned by
astRead.
If StcsProps is set to zero (the default), then the properties
will not be returned.
- Type:
- Integer (boolean).
- Class Applicability:
-
StcsChan
-
All StcsChans have this attribute.
- Notes:
- Other attributes such as StcsCoords and StcsArea can be used to
specify other Objects to be returned by
astRead.
If more than one of these attributes is set non-zero, then the
actual Object returned by
astRead
will be a KeyMap containing the requested Objects. In this
case, the properties KeyMap will be stored in the returned KeyMap
using the key "PROPS". If StcsProps is the only attribute to be
set non-zero, then the Object returned by
astRead
will be the properties KeyMap itself.
- The KeyMap containing the properties will have entries for one or
more of the following keys: "TIME_PROPS", "SPACE_PROPS", "SPECTRAL_PROPS"
and "REDSHIFT_PROPS". Each of these entries will be another KeyMap
containing the properties of the corresponding STC-S sub-phrase.
