Method Detail

getStatus

public ParseStatus getStatus()

The status of parsing the page.

getTitle

public String getTitle()

The title of the page.

getOutlinks

public Outlink[] getOutlinks()

The outlinks of the page.

getContentMeta

The original Metadata retrieved from content

getParseMeta

public Metadata getParseMeta()

Other content properties. This is the place to find format-specific properties. Different parser implementations for different content types will populate this differently.

setParseMeta

public void setParseMeta(Metadata parseMeta)

setOutlinks

public void setOutlinks(Outlink[] outlinks)

getMeta

public String getMeta(String name)

Get a metadata single value. This method first looks for the metadata value in the parse metadata. If no value is found it the looks for the metadata in the content metadata.
