Description

This component provides a mechanism to perform a first-pass split of a formatting string into its component parts in a way that is compatible with [format.string] and [time.format] in the Standard. No validation is performed by this component and further type-specific processing will be required prior to use.

Note a default-initialized FormatSpecificationParser has the following defaults:

sections: e_SECTIONS_NONE
filler: zero-terminated empty string
numFillerCharacters: 1 (the null termination)
fillerDisplayWidth: 1
alignment: e_ALIGN_DEFAULT
sign: e_SIGN_DEFAULT
alternativeFlag: false
zeroPaddingFlag: false
rawWidth: e_DEFAULT
rawPrecision: e_DEFAULT
postprocessedWidth: e_DEFAULT
postprocessedPrecision: e_DEFAULT
localeSpecificFlag: false

This component is for use within bslfmt only.
