public IFrameLinker()

Method Detail

getDescription

public String getDescription()

Description copied from class: Linker

Returns a human-readable String describing the Linker.

Specified by:

getDescription in class Linker

getCompilationExtension

protected String getCompilationExtension(TreeLogger logger,
                                         LinkerContext context)

Specified by:

getCompilationExtension in class SelectionScriptLinker

getHostedFilename

protected String getHostedFilename()

Overrides:

getHostedFilename in class SelectionScriptLinker

getModulePrefix

protected String getModulePrefix(TreeLogger logger,
                                 LinkerContext context,
                                 String strongName)
                          throws UnableToCompleteException

Description copied from class: SelectionScriptLinker

Compute the beginning of a JavaScript file that will hold the main module implementation.

Specified by:

getModulePrefix in class SelectionScriptLinker

Throws:

UnableToCompleteException

getModulePrefix

protected String getModulePrefix(TreeLogger logger,
                                 LinkerContext context,
                                 String strongName,
                                 int numFragments)
                          throws UnableToCompleteException

Description copied from class: SelectionScriptLinker

Compute the beginning of a JavaScript file that will hold the main module implementation. By default, calls SelectionScriptLinker.getModulePrefix(TreeLogger, LinkerContext, String).

Overrides:

getModulePrefix in class SelectionScriptLinker

strongName - strong name of the module being emitted

numFragments - the number of fragments for this module, including the main fragment (fragment 0)

Throws:

UnableToCompleteException

getModuleSuffix

protected String getModuleSuffix(TreeLogger logger,
                                 LinkerContext context)

Description copied from class: SelectionScriptLinker

Returns the suffix for the initial JavaScript fragment (deprecated version). The default returns null, which will cause SelectionScriptLinker.getModuleSuffix2(com.google.gwt.core.ext.TreeLogger, com.google.gwt.core.ext.LinkerContext, java.lang.String) to be called instead. Subclasses should switch to extending getModuleSuffix2.

Overrides:

getModuleSuffix in class SelectionScriptLinker

getScriptChunkSeparator

protected String getScriptChunkSeparator(TreeLogger logger,
                                         LinkerContext context)

Description copied from class: SelectionScriptLinker

Some subclasses support "chunking" of the primary fragment. If chunking will be supported, this function should be overridden to return the string which should be inserted between each chunk.

Overrides:

getScriptChunkSeparator in class SelectionScriptLinker

getSelectionScriptTemplate

protected String getSelectionScriptTemplate(TreeLogger logger,
                                            LinkerContext context)

Specified by:

getSelectionScriptTemplate in class SelectionScriptLinker

modifyPrimaryJavaScript

protected String modifyPrimaryJavaScript(String js)
