Field Detail

DBG

org.apache.log4j.Category DBG

The debugging class

---

ident

IdentNode ident

The identifier of the loop variable

---

expr

Node expr

The expression we are looping through

---

block

BlockNode block

The block to execute for each statement

Constructor Detail

ForEachNode

public ForEachNode(IdentNode ident,
                   Node expr,
                   BlockNode block)

Constructor.

Method Detail

getIdent

public IdentNode getIdent()

Get the ident we should use for the loop.

---

getExpression

public Node getExpression()

Get the expression we should use for the loop.

---

getBlock

public Node getBlock()

Get the block to use in the loop.

---

dump

public void dump()
          throws AspException

Dumps the visual representation of this script.

Specified by:

dump in interface Node

---

prepare

public void prepare(AspContext context)
             throws AspException

Prepares this statement for execution. Calls prepare on the block of statements contained within the for loop.

Specified by:

prepare in interface Node

---

execute

public java.lang.Object execute(AspContext context)
                         throws AspException

Executes this node.

Specified by:

execute in interface Node

---

executeJavaObjectNode

private void executeJavaObjectNode(JavaObjectNode javaObj,
                                   AspContext context)
                            throws AspException

Internal function which handles the enumeration of JavaObjectNode objects. XXX This is probably a bad idea, and should be moved somewhere else (like a new class: JavaArrayNode).

---

executeArrayNode

private void executeArrayNode(ArrayNode array,
                              AspContext context)
                       throws AspException

Internal function which handles the enumeration of ArrayNode object.

---

executeSimpleMap

private void executeSimpleMap(SimpleMap map,
                              AspContext context)
                       throws AspException

Internal function which handles the enumeration of SimpleMap object.
