Method Summary

Modifier and Type	Method	Description
protected Expression	annealDeclaration(ElementDeclExp exp)	This method is called after this class finishes augmenting ElementDeclExp.
protected Expression	annealExpression(Expression contentType)	performs final wrap-up and returns a fully created Expression object that represents this element.
protected Expression	castExpression(Expression halfCastedExpression, Expression newChildExpression)	combines half-made expression and newly found child expression into the expression.
protected State	createChildState(StartTagInfo tag)	creates appropriate child state object for this element
protected Expression	defaultExpression()	computes default expression.
protected Expression	initialExpression()	sets initial pattern
boolean	isGlobal()	Returns true if this element declaration is a global element declaration.
protected void	onIdentityConstraint(IdentityConstraint idc)	this method is called when an identity constraint declaration is found.
protected Expression	resolveTypeRef(java.lang.String typeQName)	If this element declaration has @type, then this method is called to resolve it.

Method Detail

createChildState

protected State createChildState(StartTagInfo tag)

Description copied from class: SimpleState

creates appropriate child state object for this element

Overrides:

createChildState in class ExpressionWithChildState

initialExpression

protected Expression initialExpression()

Description copied from class: ExpressionWithChildState

sets initial pattern

Overrides:

initialExpression in class ExpressionWithChildState

resolveTypeRef

protected Expression resolveTypeRef(java.lang.String typeQName)

If this element declaration has @type, then this method is called to resolve it. Since the type refered to may not be processed yet, a late binding is needed here.

castExpression

protected Expression castExpression(Expression halfCastedExpression,
                                    Expression newChildExpression)

Description copied from class: ExpressionWithChildState

combines half-made expression and newly found child expression into the expression.

Say this container has three child expression exp1,exp2, and exp3. Then, the expression of this state will be made by the following method invocations.

   annealExpression(
     castExpression(
       castExpression(
         castExpression(null,exp1), exp2), exp3 ) )
 

Specified by:

castExpression in class ExpressionWithChildState

defaultExpression

protected Expression defaultExpression()

Description copied from class: ExpressionWithChildState

computes default expression. this method is called before annealExpression when no child expression is given during parsing. return null to signal an error.

Overrides:

defaultExpression in class ExpressionWithChildState

annealExpression

protected Expression annealExpression(Expression contentType)

Description copied from class: ExpressionWithChildState

performs final wrap-up and returns a fully created Expression object that represents this element.

Overrides:

annealExpression in class ExpressionWithChildState

annealDeclaration

protected Expression annealDeclaration(ElementDeclExp exp)

This method is called after this class finishes augmenting ElementDeclExp. Derived classes can override this method and modify an ElementDeclExp further.

isGlobal

public boolean isGlobal()

Returns true if this element declaration is a global element declaration.

onIdentityConstraint

protected void onIdentityConstraint(IdentityConstraint idc)

this method is called when an identity constraint declaration is found.
