Regular Notation with Parameter List: $page.setTitle( "My Home
Page" )
例:
通常表記: $customer.getAddress()
正式表記: ${purchase.getTotal()}
通常表記(パラメータリスト付き): $page.setTitle( "My Home Page" )
VTL Properties can be used as a shorthand notation for VTL Methods
that take get and set. Either
$object.getMethod() or $object.setMethod() can be
abbreviated as $object.Method. It is generally preferable to
use a Property when available. The main difference between Properties
and Methods is that you can specify a parameter list to a Method.
$ref - The LHS of the assignment must be a variable
reference or a property reference.
arg - The RHS of the assignment, arg is parsed
if enclosed in double quotes, and not parsed if enclosed in single
quotes. If the RHS evaluates to null, it is not
assigned to the LHS.
arg - May be one of the following: a reference to a
list (i.e. object array, collection, or map), an array list, or
the range operator.
statement - What is output each time Velocity finds a
valid item in the list denoted above as arg. This output is
any valid VTL and is rendered each iteration of the loop.
Examples of the #foreach(), omitting the statement block :
Reference: #foreach ( $item in $items )
Array list: #foreach ( $item in ["Not", $my, "fault"] )
Range operator: #foreach ( $item in [1..3] )
#foreach() の例を示します(statement ブロックは省略しています):
リファレンス: #foreach ( $item in $items )
配列リスト: #foreach ( $item in ["Not", $my, "fault"] )
範囲演算子: #foreach ( $item in [1..3] )
Velocity provides an easy way to get the loop counter so that you
can do something like the following:
Velocity は、以下のようにループ回数を取得する簡単な方法を提供します:
#foreach( $customer in $customerList )
$velocityCount
$customer.Name
#end
]]>
The default name for the loop counter variable reference, which is
specified in the velocity.properties file, is $velocityCount. By
default the counter starts at 1, but this can be set to either 0 or
1 in the velocity.properties file. Here's what the loop
counter properties section of the velocity.properties
file appears:
$arg1 $arg2 [ ... ] - Arguments to the VM. There can be
any number of arguments, but the number used at invocation must
match the number specified in the definition.
[ VM VTL code... ] - Any valid VTL code, anything you
can put into a template, can be put into a VM.
