getContext

public IEglContext getContext()

setContext

public void setContext(IEglContext context)

initialiseRoot

public boolean initialiseRoot(URI root)

Sets the root of this template factory, unless it has already been set.

Parameters:

root - The new root.

Returns:

true if the root was set as a result of this call, false if the root had already been initialized.

setRoot

public void setRoot(URI root)

getTemplateRoot

public String getTemplateRoot()

setTemplateRoot

public void setTemplateRoot(String path)
                     throws EglRuntimeException

Throws:

EglRuntimeException

resolveRoot

protected URI resolveRoot(String path)
                   throws EglRuntimeException

Throws:

EglRuntimeException

resolveTemplate

public URI resolveTemplate(String path)
                    throws EglRuntimeException

Throws:

EglRuntimeException

name

protected String name(String path)

load

public EglTemplate load(File file)
                 throws EglRuntimeException

Loads an EglTemplate for the EGL code stored in the indicated file. Subclasses should override #createTemplate(String, URI), rather than this method, unless they wish to alter the way in which a file is transformed into an EglTemplateSpecification

Throws:

EglRuntimeException

load

protected EglTemplate load(String code,
                           File file)
                    throws EglRuntimeException

Loads an EglTemplate for the given EGL code as though it were contained in the given File. Used for parsing "dirty" code (which has not yet been saved to disk). Subclasses should override #createTemplate(String, URI), rather than this method, unless they wish to alter the way in which a dirty resource is transformed into an EglTemplateSpecification

Throws:

EglRuntimeException

load

public EglTemplate load(String path)
                 throws EglRuntimeException

Loads an EglTemplate for the EGL code stored in the file at path. Subclasses should override #createTemplate(String, URI), rather than this method, unless they wish to alter the way in which a path is transformed into an EglTemplateSpecification

Throws:

EglRuntimeException

load

public EglTemplate load(URI resource)
                 throws EglRuntimeException

Loads an EglTemplate for the EGL code stored in the given resource. Subclasses should override #createTemplate(String, URI), rather than this method, unless they wish to alter the way in which a resource is transformed into an EglTemplateSpecification

Throws:

EglRuntimeException

load

protected EglTemplate load(String code,
                           URI resource)
                    throws EglRuntimeException

Loads an EglTemplate for the given EGL code as though it were contained in the given URI. Used for parsing "dirty" code (which has not yet been saved to disk). Subclasses should override #createTemplate(String, URI), rather than this method, unless they wish to alter the way in which a dirty resource is transformed into an EglTemplateSpecification

Throws:

EglRuntimeException

load

protected final EglTemplate load(EglTemplateSpecification spec)
                          throws EglRuntimeException

Loads an EglTemplate from the given EglTemplateSpecification. Subclasses should override #createTemplate(String, URI), rather than this method, unless they wish to alter the way in which IOExceptions are handled, in which case they should override handleFailedLoad(String, Exception).

Throws:

EglRuntimeException

handleFailedLoad

protected EglTemplate handleFailedLoad(String name,
                                       Exception e)
                                throws EglRuntimeException

Throws:

EglRuntimeException

prepare

public final EglTemplate prepare(String code)
                          throws Exception

Prepares an EGL template that will execute the given EGL source code. Subclasses should override #createTemplate(String), rather than this method, as this method may, in the future, acquire additional responsibilities, such as exception handling.

Throws:

Exception

createTemplate

protected EglTemplate createTemplate(EglTemplateSpecification spec)
                              throws Exception

Creates a template from the given specification. Subclasses may override to create different types of template.

Throws:

Exception

copyState

public void copyState(IEolContext delegate)

getContextForNewTemplate

protected IEglContext getContextForNewTemplate()

This method should be called when creating a new template from createTemplate(EglTemplateSpecification). The rationale is that in some cases this factory's context is not safe to be used directly, so a proxy or modifications may be needed instead.

Returns:

An appropriate context to be used for a new EglTemplate instance.

toString

public String toString()

Overrides:

toString in class Object
