org.apache.xalan.extensions.ExpressionContext

Packages that use ExpressionContext

Package	Description
org.apache.xalan.extensions	Implementation of Xalan Extension Mechanism.
org.apache.xalan.lib	Extension elements and functions shipped with Xalan-Java, including EXSLT functions.
org.apache.xalan.lib.sql	Provides extension functions for connecting to a JDBC data source, executing a query, and working incrementally through a "streamable" result set.

Uses of ExpressionContext in org.apache.xalan.lib

Methods in org.apache.xalan.lib with parameters of type ExpressionContext

Modifier and Type	Method and Description
static Node	Extensions.checkEnvironment(ExpressionContext myContext) Return a Node of basic debugging information from the EnvironmentCheck utility about the Java environment.
static NodeList	ExsltDynamic.closure(ExpressionContext myContext, NodeList nl, String expr) The dyn:closure function creates a node set resulting from transitive closure of evaluating the expression passed as the second argument on each of the nodes passed as the first argument, then on the node set resulting from that and so on until no more nodes are found.
static int	NodeInfo.columnNumber(ExpressionContext context) columnNumber returns the column number of the current context node.
static XObject	Extensions.evaluate(ExpressionContext myContext, String xpathExpr) Returns the result of evaluating the argument as a string containing an XPath expression.
static XObject	ExsltDynamic.evaluate(ExpressionContext myContext, String xpathExpr) The dyn:evaluate function evaluates a string as an XPath expression and returns the resulting value, which might be a boolean, number, string, node set, result tree fragment or external object.
static int	NodeInfo.lineNumber(ExpressionContext context) lineNumber returns the line number of the current context node.
static NodeList	ExsltDynamic.map(ExpressionContext myContext, NodeList nl, String expr) The dyn:map function evaluates the expression passed as the second argument for each of the nodes passed as the first argument, and returns a node set of those values.
static double	ExsltDynamic.max(ExpressionContext myContext, NodeList nl, String expr) The dyn:max function calculates the maximum value for the nodes passed as the first argument, where the value of each node is calculated dynamically using an XPath expression passed as a string as the second argument.
static double	ExsltDynamic.min(ExpressionContext myContext, NodeList nl, String expr) The dyn:min function calculates the minimum value for the nodes passed as the first argument, where the value of each node is calculated dynamically using an XPath expression passed as a string as the second argument.
static NodeSet	Extensions.nodeset(ExpressionContext myProcessor, Object rtf) This method is an extension that implements as a Xalan extension the node-set function also found in xt and saxon.
static NodeSet	ExsltCommon.nodeSet(ExpressionContext myProcessor, Object rtf) The exsl:node-set function converts a result tree fragment (which is what you get when you use the content of xsl:variable rather than its select attribute to give a variable value) into a node set.
static String	NodeInfo.publicId(ExpressionContext context) publicId returns the public identifier of the current context node.
static double	ExsltDynamic.sum(ExpressionContext myContext, NodeList nl, String expr) The dyn:sum function calculates the sum for the nodes passed as the first argument, where the value of each node is calculated dynamically using an XPath expression passed as a string as the second argument.
static String	NodeInfo.systemId(ExpressionContext context) systemId returns the system id of the current context node.
