Class JellyContextAdapter
java.lang.Object
|
+--org.apache.commons.jelly.tags.velocity.JellyContextAdapter
- All Implemented Interfaces:
- org.apache.velocity.context.Context
- public class JellyContextAdapter
- extends java.lang.Object
- implements org.apache.velocity.context.Context
Adapts a JellyContext for use as a Velocity Context. This context
can be used in either read-only or read-write mode. When used as a
read-only adapter, items put or removeed from the
Velocity context are not permitted to propogate to the JellyContext,
which is the default behavior. The adapter can also be used in a
read-write mode. This permits changes made by Velocity to propogate
to the JellyContext.

JellyContextAdapter
public JellyContextAdapter(org.apache.commons.jelly.JellyContext jellyContext)
- Constructor.
- Parameters:
jellyContext
- The JellyContext to adapt
setReadOnly
public void setReadOnly(boolean readOnly)
- Sets the read-only flag for this adapter. If the read-only flag
is set, changes to the Velocity Context will not be propogated to
the JellyContext. Turning the read-only flag off enables changes
to propogate.
- Parameters:
readOnly
- If this parameter is true, the adapter
becomes read-only. Setting the parameter to false the
adapter becomes read-write.
isReadOnly
public boolean isReadOnly()
- Tests if the adapter is read-only.
- Returns:
- true if the adpater is read-only; otherwise
returns false.
