Modifier and Type	Method	Description
protected void	addMessage(String message)
protected abstract void	doGenerate(File file, String targetName, boolean overwrite, boolean merge)	Store result of processing template in the given file.

Method Details

resolveFile

protected File resolveFile(String path)
                    throws EglRuntimeException

Throws:

EglRuntimeException

store

public void store(String path)
           throws EglRuntimeException

Deprecated.

Use generate(path) instead, or generate(path, false, false), if you really know what you are doing :-)

This processes the template and stores the result in the given file, provided that this file does not exist yet. This method is here for backward compatibility only.

Parameters:

path -

Throws:

EglRuntimeException

store

public void store(String path,
 boolean overwrite)
           throws EglRuntimeException

Deprecated.

Use generate(path) instead, or generate(path, overwrite, false), if you really know what you are doing :-)

This processes the template and stores the result in the given file. If overwrite is false, an existing file will prevent the result from being written. If overwrite is true, any existing file will be overwritten, not respecting protected regions. This method is here for backward compatibility only.

Parameters:

path -

overwrite -

Throws:

EglRuntimeException

generate

public final void generate(String path)
                    throws EglRuntimeException

The preferred way of generating code from a persistent template, this stores the generation result in the given file, maintaining any protected regions.

Parameters:

path -

Throws:

EglRuntimeException

generate

public File generate(String path,
 boolean overwrite,
 boolean merge)
              throws EglRuntimeException

Fully parameterised version of generate, usually only used internally. Setting overwrite to false implies merge is ignored.

Parameters:

path -

overwrite -

merge -

Returns:

The output file.

Throws:

EglRuntimeException

name

protected String name(String path)

doGenerate

protected abstract void doGenerate(File file,
 String targetName,
 boolean overwrite,
 boolean merge)
                            throws EglRuntimeException

Store result of processing template in the given file. Subclasses should override to implement the specific semantics of 'storing' to a file. The result of processing the template will be available from EglTemplate.contents.

Parameters:

path -

targetName -

overwrite -

merge -

Throws:

EglRuntimeException

addMessage

protected void addMessage(String message)
