Method Detail
-
getName
public java.lang.String getName()
Return name of this Velocimacro.
-
getType
public int getType()
Velocimacros are always LINE type directives.
-
setName
public void setName(java.lang.String name)
sets the directive name of this VM- Parameters:
name
-
-
setArgArray
public void setArgArray(java.lang.String[] arr)
sets the array of arguments specified in the macro definition- Parameters:
arr
-
-
setNodeTree
public void setNodeTree(SimpleNode tree)
- Parameters:
tree
-
-
getNumArgs
public int getNumArgs()
returns the number of ars needed for this VM- Returns:
- The number of ars needed for this VM
-
render
public boolean render(InternalContextAdapter context, java.io.Writer writer, Node node) throws java.io.IOException, MethodInvocationException, MacroOverflowException
Description copied from class:Directive
How this directive is to be rendered- Specified by:
render
in classDirective
- Returns:
- True if the directive rendered successfully.
- Throws:
java.io.IOException
MethodInvocationException
MacroOverflowException
-
render
public boolean render(InternalContextAdapter context, java.io.Writer writer, Node node, Renderable body) throws java.io.IOException, MethodInvocationException, MacroOverflowException
Renders the macro using the context.- Parameters:
context
- Current rendering contextwriter
- Writer for outputnode
- AST that calls the macro- Returns:
- True if the directive rendered successfully.
- Throws:
java.io.IOException
MethodInvocationException
MacroOverflowException
-
init
public void init(RuntimeServices rs)
Initialize members of VelocimacroProxy. called from MacroEntry
-
checkArgs
public void checkArgs(InternalContextAdapter context, Node node, boolean hasBody)
check if we are calling this macro with the right number of arguments. If we are not, and strictArguments is active, then throw TemplateInitException. This method is called during macro render, so it must be thread safe.
