Uses of Expression in org.apache.commons.jelly

Methods in org.apache.commons.jelly that return Expression

Expression

TagLibrary.createExpression(ExpressionFactory factory, TagScript tagScript, java.lang.String attributeName, java.lang.String attributeValue) Allows taglibs to use their own expression evaluation mechanism

Uses of Expression in org.apache.commons.jelly.expression

Classes in org.apache.commons.jelly.expression that implement Expression

class	CompositeExpression CompositeExpression is a Composite expression made up of several Expression objects which are concatenated into a single String.
class	ConstantExpression ConstantExpression represents a constant expression.
class	ExpressionSupport ExpressionSupport an abstract base class for Expression implementations which provides default implementations of some of the typesafe evaluation methods.

Methods in org.apache.commons.jelly.expression that return Expression

Expression	ExpressionFactory.createExpression(java.lang.String text) Creates a new expression for the given text
static Expression	CompositeExpression.parse(java.lang.String text, ExpressionFactory factory) Parses the given String to be either a ConstantExpresssion, an Expression denoted as "${foo}" or some String with embedded expresssions such as "abc${something}def${else}xyz" which results in a CompositeExpression being returned.

Methods in org.apache.commons.jelly.expression with parameters of type Expression
