Constructor Detail

ASTStringLiteral

public ASTStringLiteral(int id)
Parameters:
id -

ASTStringLiteral

public ASTStringLiteral(Parser p,
                        int id)
Parameters:
p -
id -
Method Detail

init

public Object init(InternalContextAdapter context,
                   Object data)
            throws TemplateInitException
init : we don't have to do much. Init the tree (there shouldn't be one) and then see if interpolation is turned on.

Specified by:
init in interface Node
Overrides:
init in class SimpleNode
Parameters:
context -
data -
Returns:
Init result.
Throws:
TemplateInitException
See Also:
Node.init(org.apache.velocity.context.InternalContextAdapter, java.lang.Object)

adjTokenLineNums

public void adjTokenLineNums(Node node)
Adjust all the line and column numbers that comprise a node so that they are corrected for the string literals position within the template file. This is neccessary if an exception is thrown while processing the node so that the line and column position reported reflects the error position within the template and not just relative to the error position within the string literal.


unescape

public static String unescape(String string)
Since:
1.6

jjtAccept

public Object jjtAccept(ParserVisitor visitor,
                        Object data)
Specified by:
jjtAccept in interface Node
Overrides:
jjtAccept in class SimpleNode
Returns:
The Node execution result object.
See Also:
SimpleNode.jjtAccept(org.apache.velocity.runtime.parser.node.ParserVisitor, java.lang.Object)

isConstant

public boolean isConstant()
Check to see if this is an interpolated string.

Returns:
true if this is constant (not an interpolated string)
Since:
1.6

value

public Object value(InternalContextAdapter context)
renders the value of the string literal If the properties allow, and the string literal contains a $ or a # the literal is rendered against the context Otherwise, the stringlit is returned.

Specified by:
value in interface Node
Overrides:
value in class SimpleNode
Parameters:
context -
Returns:
result of the rendering.
See Also:
Node.value(org.apache.velocity.context.InternalContextAdapter)
