Detailed Description

A helper class for validating identity constraints.

This class represents a field node from the key-sequence as defined in the validation rules at http://www.w3.org/TR/xmlschema11-1/#d0e32243.

Definition at line 73 of file qxsdidchelper_p.h.

Constructors and Destructors

FieldNode() [1/2]

FieldNode::FieldNode

(

)

Creates an empty field node.

Definition at line 51 of file qxsdidchelper.cpp.

{
}

FieldNode() [2/2]

FieldNode::FieldNode	(	const QXmlItem &	item,
		const QString &	data,
		const SchemaType::Ptr &	type
	)

Creates a field node that is bound to a xml node.

Parameters

item	The xml node the field is bound to.
data	The string content of that field.
type	The type that is bound to that field.

Definition at line 55 of file qxsdidchelper.cpp.

    : m_item(item)
    , m_data(data)
    , m_type(type)
{
}

Functions

isEmpty()

bool FieldNode::isEmpty

(

)

const

Returns whether this field is empty.

A field can be empty, if the xpath expression selects an absent attribute or element.

Definition at line 62 of file qxsdidchelper.cpp.

{
    return m_item.isNull();
}

isEqualTo()

bool FieldNode::isEqualTo	(	const FieldNode &	other,
		const NamePool::Ptr &	namePool,
		const ReportContext::Ptr &	context,
		const SourceLocationReflection *const	reflection
	)		const

Returns whether this field is equal to the other field.

Equal means that both have the same type and there content is equal in the types value space.

Definition at line 67 of file qxsdidchelper.cpp.

{
    if (m_type != other.m_type)
        return false;

    const DerivedString<TypeString>::Ptr string = DerivedString<TypeString>::fromLexical(namePool, m_data);
    const DerivedString<TypeString>::Ptr otherString = DerivedString<TypeString>::fromLexical(namePool, other.m_data);

    return XsdSchemaHelper::constructAndCompare(string, AtomicComparator::OperatorEqual, otherString, m_type, context, reflection);
}

item()

QXmlItem FieldNode::item

(

)

const

Returns the xml node item the field is bound to.

Definition at line 78 of file qxsdidchelper.cpp.

{
    return m_item;
}
