Method Detail

sharedInstance

public static DataExpressionParser sharedInstance()

Returns the shared DataExpressionParser instance.

getName

public java.lang.String getName()

Description copied from class: ExpressionParser

gets the name of this bindingParser

Overrides:

getName in class ExpressionParser

isBinding

public boolean isBinding(ExpressionContext context,
                         java.lang.String attrURI,
                         java.lang.String attrName,
                         java.lang.String attrText)

Overrides:

isBinding in class ExpressionParser

Following copied from class: oracle.cabo.share.expl.ExpressionParser

Parameters:

context - the binding context

attrURI - the attribute namespace

attrName - the attribute name

attrText - the attribute string value

Returns:

true if the value for the specified attribute is not a literal and needs to be parsed into a BoundValue by ExpressionParser.parseExpression(oracle.cabo.share.expl.ExpressionContext, java.lang.String, java.lang.Class).

parseExpression

public java.lang.Object parseExpression(ExpressionContext context,
                                        java.lang.String attrText,
                                        java.lang.Class attrType)
                                 throws ExplException

Returns the parsed binding as a bound value or literal. If the namespace is a data bound namespace, then a bound value is parsed, otherwise a literal is parsed.

Overrides:

parseExpression in class ExpressionParser

Parameters:

context - the binding context

attrText - the attribute string value

attrType - the type of the parsed literal or the return type of the parsed bound value

Returns:

the parsed binding as a bound value or literal
