Method Detail

getCodes

public Code[] getCodes()

Specified by:

getCodes in interface Code

init

public void init()

Specified by:

init in interface Code

setCodes

public void setCodes(Code[] newcodes)

Specified by:

setCodes in interface Code

get

public java.lang.Object get(java.lang.Object[] scopes)

Retrieve the first value in the stacks of scopes that matches the give name. The method wrappers are cached and guarded against the type or number of scopes changing.

Methods will be found using the object handler, called here with another lookup on a guard failure and finally coerced to a final value based on the ObjectHandler you provide.

Parameters:

scopes - An array of scopes to interrogate from right to left.

Returns:

The value of the field or method

getWrapper

protected Wrapper getWrapper(java.lang.String name,
                             java.lang.Object[] scopes)

execute

public java.io.Writer execute(java.io.Writer writer,
                              java.lang.Object scope)

Specified by:

execute in interface Code

execute

public java.io.Writer execute(java.io.Writer writer,
                              java.lang.Object[] scopes)

The default behavior is to run the codes and append the captured text.

Specified by:

execute in interface Code

Parameters:

writer - The writer to write the output to

scopes - The scopes to evaluate the embedded names against.

identity

public void identity(java.io.Writer writer)

Specified by:

identity in interface Code

runIdentity

protected void runIdentity(java.io.Writer writer)

appendText

protected java.io.Writer appendText(java.io.Writer writer)

runCodes

protected java.io.Writer runCodes(java.io.Writer writer,
                                  java.lang.Object[] scopes)

append

public void append(java.lang.String text)

Specified by:

append in interface Code

addScope

protected java.lang.Object[] addScope(java.lang.Object next,
                                      java.lang.Object[] scopes)

Allocating new scopes is currently the only place where we are activtely allocating memory within the templating system. It is possible that recycling these might lend some additional benefit or using the same one in each thread. The only time this grows is when there are recursive calls to the same scope. In most non-degenerate cases we won't encounter that. Also, since we are copying the results across these boundaries we don't have to worry about threads.
