Detailed Description

This class encapsulates information about the standard structure namespaces and provides some utility methods connected to them.

This class encapsulates information about the standard structure namespaces and provides some utility methods connected to them. The main purpose of this class is to determine if the given role in the specified namespace belongs to the standard or known domain-specific namespace.

See ISO 32000-2 14.8.6, "Standard structure namespaces"

GetDefault()

static String iText.Kernel.Pdf.Tagging.StandardNamespaces.GetDefault ( )

inlinestatic

Gets the name of the default standard structure namespace.

Gets the name of the default standard structure namespace. When a namespace is not explicitly specified for a given structure element or attribute, it shall be assumed to be within this default standard structure namespace. According to ISO 32000-2 default namespace is PDF_1_7.

Returns

the name of the default standard structure namespace.

IsHnRole()

static bool iText.Kernel.Pdf.Tagging.StandardNamespaces.IsHnRole ( String  role )

inlinestatic

Checks if the given role matches the Hn role pattern.

Checks if the given role matches the Hn role pattern. To match this pattern, the given role shall always consist of the uppercase letter "H" and one or more digits, representing an unsigned integer greater than or equal to 1, without leading zeroes or any other prefix or postfix.

Parameters

role	a System.String that specifies a role to be checked against Hn role pattern.

Returns

true if the role matches, false otherwise.

IsKnownDomainSpecificNamespace()

static bool iText.Kernel.Pdf.Tagging.StandardNamespaces.IsKnownDomainSpecificNamespace ( PdfNamespace @  namespace )

inlinestatic

Checks if the given namespace is identified as the one that is common within broad ranges of documents types and doesn't require a role mapping for it's roles.

Parameters

namespace

a namespace to be checked, whether it defines a namespace of the known domain specific language.

Returns

true, if the given PdfNamespace belongs to the domain-specific namespace, false otherwise.

RoleBelongsToStandardNamespace()

static bool iText.Kernel.Pdf.Tagging.StandardNamespaces.RoleBelongsToStandardNamespace ( String  role, String  standardNamespaceName  )

inlinestatic

Checks if the given role is considered standard in the specified standard namespace.

Parameters

role	a role to be checked if it is standard in the given standard structure namespace.
standardNamespaceName	a System.String identifying standard structure namespace against which given role will be checked.

Returns

false if the given role doesn't belong to the standard roles of the given standard structure namespace or if the given namespace name is not standard; true otherwise.
