com.webobjects.eoaccess.EOSQLExpressionFactory.createExpression()
net.sf.saxon.sxpath.XPathEvaluator.createExpression()
Prepare (compile) an XPath expression for subsequent evaluation. @param expression The XPath expression to be compiled, supplied as a string. @return an XPathExpression object representing the prepared expression @throws XPathException if the syntax of the expression is wrong, or if it references namespaces,variables, or functions that have not been declared.
net.sf.saxon.xpath.XPathEvaluator.createExpression()
Prepare an XPath expression for subsequent evaluation. @param expression The XPath expression to be evaluated, supplied as a string. @return an XPathExpression object representing the prepared expression @throws net.sf.saxon.trans.XPathException if the syntax of the expression is wrong, or if it references namespaces,variables, or functions that have not been declared. @deprecated since Saxon 8.9 - use {@link #compile(String)}

org.apache.camel.spi.Language.createExpression()
org.apache.commons.jelly.TagLibrary.createExpression()
Allows taglibs to use their own expression evaluation mechanism
org.apache.commons.jexl2.JexlEngine.createExpression()
An overridable through covariant return Expression creator. @param text the script text @param tree the parse AST tree @return the script instance
org.camunda.bpm.engine.impl.el.ExpressionManager.createExpression()
org.codehaus.aspectwerkz.definition.expression.ExpressionNamespace.createExpression()
Creates an new strongly typed leaf expression. @param expression @param type @return the expression
org.jboss.security.xacml.core.model.policy.ObjectFactory.createExpression()
Create an instance of {@link JAXBElement }{@code <}{@link ExpressionType }{@code>}}
org.pdf4j.saxon.sxpath.XPathEvaluator.createExpression()
Prepare (compile) an XPath expression for subsequent evaluation. @param expression The XPath expression to be compiled, supplied as a string. @return an XPathExpression object representing the prepared expression @throws XPathException if the syntax of the expression is wrong, or if it references namespaces,variables, or functions that have not been declared.
org.sql.generation.api.grammar.builders.booleans.BooleanBuilder.createExpression()
org.sql.generation.api.grammar.builders.booleans.InBuilder.createExpression()
org.sql.generation.api.grammar.builders.definition.TableElementListBuilder.createExpression()
org.sql.generation.api.grammar.builders.modification.ColumnSourceByValuesBuilder.createExpression()

org.sql.generation.api.grammar.builders.modification.UpdateBySearchBuilder.createExpression()
org.sql.generation.api.grammar.builders.query.QueryBuilder.createExpression()
org.sql.generation.api.grammar.builders.query.QuerySpecificationBuilder.createExpression()
org.w3c.dom.xpath.XPathEvaluator.createExpression()
Creates a parsed XPath expression with resolved namespaces. This is useful when an expression will be reused in an application since it makes it possible to compile the expression string into a more efficient internal form and preresolve all namespace prefixes which occur within the expression. @param expression The XPath expression string to be parsed. @param resolver The resolver permits translation ofprefixes within the XPath expression into appropriate namespace URIs . If this is specified as null, any namespace prefix within the expression will result in DOMException being thrown with the code NAMESPACE_ERR. @return The compiled form of the XPath expression. @exception XPathException INVALID_EXPRESSION_ERR: Raised if the expression is not legal according to the rules of the XPathEvaluatori @exception DOMException NAMESPACE_ERR: Raised if the expression contains namespace prefixes which cannot be resolved by the specified XPathNSResolver.
