                 PrefixedName[] names)

Method Detail

newInstance

public StructValidator newInstance()

Sequence content specification is always stateful; can not use a shared instance... so let's create new instance:

Specified by:

newInstance in class StructValidator

tryToValidate

public java.lang.String tryToValidate(PrefixedName elemName)

Description copied from class: StructValidator

Method called when a new (start) element is encountered within the scope of parent element this validator monitors.

Specified by:

tryToValidate in class StructValidator

Returns:

Null if element is valid in its current position; error message if not.

fullyValid

public java.lang.String fullyValid()

Description copied from class: StructValidator

Method called when the end element of the scope this validator validates is encountered. It should make sure that the content model is valid, and if not, to construct an error message.

Specified by:

fullyValid in class StructValidator

Returns:

Null if the content model for the element is valid; error message if not.

expElem

private java.lang.String expElem(int step)

concatNames

static final java.lang.String concatNames(PrefixedName[] names)
