List of registerFunction() Examples

Examples of registerFunction()

ca.nengo.math.impl.DefaultFunctionInterpreter.registerFunction()
@see ca.nengo.math.FunctionInterpreter#registerFunction(java.lang.String,ca.nengo.math.Function)
chrriis.dj.nativeswing.swtimpl.components.JWebBrowser.registerFunction()
Register a function to the web browser which can be called from Javascript. @param function the function to add.
com.alibaba.druid.sql.visitor.SQLEvalVisitor.registerFunction()
org.apache.pig.PigServer.registerFunction()
Defines an alias for the given function spec. This is useful for functions that require arguments to the constructor. @param function - the new function alias to define. @param functionSpec - the name of the function and any arguments.It should have the form: classname('arg1', 'arg2', ...) @deprecated Use {@link #registerFunction(String,FuncSpec)}
org.boris.jxll.Addin.registerFunction()
org.jaxen.SimpleFunctionContext.registerFunction()
Register a new function.
By registering a new function, any XPath expression that utilizes this FunctionContext may refer-to and use the new function.

Functions may exist either in an namespace or not. Namespace prefix-to-URI resolution is the responsibility of a {@link NamespaceContext}. Within this FunctionContext functions are only referenced using the URI, not the prefix.

The namespace URI of a function may be null to indicate that it exists without a namespace.
@param namespaceURI The namespace URI of the function tobe registered with this context. @param localName The non-prefixed local portion of thefunction to be registered with this context. @param function A {@link Function} implementation objectto be used when evaluating the function.
org.jaxen.XPathFunctionContext.registerFunction()
org.springframework.expression.spel.support.StandardEvaluationContext.registerFunction()
