Method Detail

analyze

public boolean analyze(ISourceLocation location,
              Collection<ICompilerProblem> problems)

Description copied from class: TranscoderBase

Analyze the attributes

Overrides:

analyze in class ImageTranscoder

Parameters:

location - Source location from where the embed came from

problems - Any problems discovered in the EmbedNode

Returns:

false if analyze failed

checkAttributeValues

protected boolean checkAttributeValues(ISourceLocation location,
                           Collection<ICompilerProblem> problems)

Description copied from class: TranscoderBase

Verify the attributes are valid for the specific transcoder

Overrides:

checkAttributeValues in class ScalableTranscoder

Returns:

false if contains invalid attributes

setAttribute

protected boolean setAttribute(EmbedAttribute attribute)

Description copied from class: TranscoderBase

Stores the supported attribute of the transcoder

Overrides:

setAttribute in class ImageTranscoder

Returns:

false if a non-supported attribute

doTranscode

protected Map<String,ICharacterTag> doTranscode(Collection<ITag> tags,
                                    Collection<ICompilerProblem> problems)

Description copied from class: TranscoderBase

Transcode the embedded asset

Overrides:

doTranscode in class ImageTranscoder

Parameters:

tags - The collection of transcoded asset tags

problems - The collection of compiler problems to which this method will add problems.

Returns:

map of symbol name to character asset tags. null if error
