Constructor Detail

AbstractAttribute

public AbstractAttribute(XmlNode parent,
                         java.lang.String name,
                         boolean required,
                         boolean supported)

Constructs attribute.

Parameters:

parent - parent of constructed attribute

name - name of constructed attribute

required - if true this attribute is required; otherwise this attribute is optional

supported - if true this attribute is supported; otherwise this attribute is unsupported

Method Detail

getParent

public XmlNode getParent()

Description copied from interface: Attribute

Gets parent node of attribute.

Specified by:

getParent in interface Attribute

Returns:

parent node of attribute

getName

public java.lang.String getName()

Description copied from interface: Attribute

Gets name of attribute.

Specified by:

getName in interface Attribute

Returns:

name of attribute

getFullName

public java.lang.String getFullName()

Description copied from interface: Attribute

Gets full name of attribute (full path from root node up to node's parent and node's name).

Specified by:

getFullName in interface Attribute

Returns:

full name of attribute (full path from root node up to node's parent and node's name)

isRequired

public boolean isRequired()

Description copied from interface: Attribute

Returns true if attribute is mandatory; false otherwise (attribute is optional).

Specified by:

isRequired in interface Attribute

Returns:

true if attribute is mandatory; false otherwise (attribute is optional)

isSupported

public boolean isSupported()

Description copied from interface: Attribute

Returns true if attribute is supported; false otherwise (attribute is not supported). This approach enables to load test even if there are unknown (not supported) attributes.

Specified by:

isSupported in interface Attribute

Returns:

true if attribute is supported; false otherwise (attribute is not supported)

setSupported

public void setSupported(boolean supported)

Sets whenever this attribute is supported or not.

Specified by:

setSupported in interface Attribute

Parameters:

supported - if true this attribute is supported; otherwise this attribute is unsupported

getLoadedValue

public java.lang.String getLoadedValue()

Description copied from interface: Attribute

Gets loaded attribute's value. If attribute has not string baseType loaded value can be different from value. For example if we have integer attribute, loaded value is a10, but value is null (a10 is not valid integer). This approach enables to load test even if there are errors.

Specified by:

getLoadedValue in interface Attribute

Returns:

loaded attribute's value

setLoadedValue

protected void setLoadedValue(java.lang.String loadedValue)

Sets new loaded value.

Parameters:

loadedValue - new loaded value

See Also:

getLoadedValue()

getLoadingProblem

public QTIParseException getLoadingProblem()

Description copied from interface: Attribute

Gets parse exception (if there were problem while loading) or null.

Specified by:

getLoadingProblem in interface Attribute

Returns:

parse exception (if there were problem while loading) or null

setLoadingProblem

protected void setLoadingProblem(QTIParseException loadingProblem)

Sets new loading problem.

Parameters:

loadingProblem - loading problem.

See Also:

getLoadingProblem()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toXmlString

public java.lang.String toXmlString(boolean printDefaultValue)

Description copied from interface: Attribute

Gets attribute converted to string (name="value"). If value is not defined or is same as defaultValue (and printDefaultValue is false), returns empty (but not null) string.

Specified by:

toXmlString in interface Attribute

Parameters:

printDefaultValue - if true, default value is printed; otherwise default value is not printed

Returns:

attribute converted to string (name="value")

validate

Description copied from interface: Validatable

Validates this object.

Specified by:
