Method Detail

getQualifiedName

protected QualifiedName getQualifiedName(java.lang.String property)

Returns the property name converted to a qualified name.

Parameters:

property - the property to convert.

Returns:

the property name converted to a qualified name.

getDescriptionValue

protected java.lang.Object getDescriptionValue(QualifiedName qualifiedName,
                                               java.lang.Object value)

Returns the given property's Eclipse value converted to EMF's corresponding basic value.

Parameters:

qualifiedName - the name of the property for which this value applies.

value - the value to convert.

Returns:

the given property's Eclipse value converted to EMF's corresponding basic value.

contentDescription

public java.util.Map<java.lang.String,java.lang.Object> contentDescription(URI uri,
                                                                           java.io.InputStream inputStream,
                                                                           java.util.Map<?,?> options,
                                                                           java.util.Map<java.lang.Object,java.lang.Object> context)
                                                                    throws java.io.IOException

This implementation delegates to the platform's content description support,

Specified by:

contentDescription in interface ContentHandler

Overrides:

contentDescription in class ContentHandlerImpl

Parameters:

uri - the URI for which to determine the content description.

inputStream - the input stream associated with the given URI.

options - a map of options to direct what kind of description is needed.

context - a map of contextual information that content handlers use to store partially computed results.

Returns:

a map of properties that describe the content of the given URI's corresponding input stream.

Throws:

java.io.IOException - if there is a problem reading the stream.

getCharset

protected java.lang.String getCharset(URI uri,
                                      java.io.InputStream inputStream,
                                      java.util.Map<?,?> options,
                                      java.util.Map<java.lang.Object,java.lang.Object> context)
                               throws java.io.IOException

This implementation only gets called when platform's content describer throws an exception, i.e., when the resource doesn't exist. For platform resource URIs, it determines the character set from the workspace.

Overrides:

getCharset in class ContentHandlerImpl

Parameters:

uri - the URI of the input stream.

inputStream - the input stream.

options - any options that might influence the interpretation of the content.

context - a cache for previously computed information.

Returns:

the character set of the input stream.

Throws:

java.io.IOException - if there is a problem loading the content.

Since:

2.9

getLineDelimiter

protected java.lang.String getLineDelimiter(URI uri,
                                            java.io.InputStream inputStream,
                                            java.util.Map<?,?> options,
                                            java.util.Map<java.lang.Object,java.lang.Object> context)
                                     throws java.io.IOException

This implementation only gets called when platform's content describer throws an exception, i.e., when the resource doesn't exist. For platform resource URIs, it determines the line delimiter from the project/workspace preferences.

Overrides:

getLineDelimiter in class ContentHandlerImpl

Parameters:

uri - the URI of the input stream.

inputStream - the input stream.

options - any options that might influence the interpretation of the content.

context - a cache for previously computed information.

Returns:

the line delimiter of the input stream.

Throws:

java.io.IOException - if there is a problem loading the content.

Since:
